Rockbox

Hi,

the random_folder_advance_config plugin fails to build the
folders on N900 / RaaA. I guess it suffers from the same
as the database update did in the past: It probably follows
starts over and over again in the /proc or /sys filesystem.

Scrolling the scrollwheel doesn't count as a button press for the Textviewer plugin's idle Timeout.

Hello,

empty menu items crash rockbox due to NULL pointer access.
Easily reproducable with the "LCD settings" in RaaA / SDL app build.

The resulting valgrind trace looks like this:
==22619== Invalid read of size 4
==22619== at 0x407FDA: do_menu (menu.c:555)
==22619== by 0x41B198: miscscrn (root_menu.c:323)
==22619== by 0x41B377: load_screen (root_menu.c:520)
==22619== by 0x41B72A: root_menu (root_menu.c:688)
==22619== by 0x406DFA: main (main.c:196)
==22619== Address 0x0 is not stack'd, malloc'd or (recently) free'd

Question:
Should we protect against "menu→submenus" being NULL or
should the menu system hide empty menus without any items at all?

Cheers,
Thomas

I’m using revision 29572 of android port. Host system is Samsung Galaxy 3 i5800, with 240×400 resolution display, with version 2.2 (Froyo) of Android.

The problem is as follows. When trying to start playback of OGG or SPX files, the playback does not start occasionally (the change is maybe less than 20% to have playback). By rewinding randomly it is possible to get it start playback. The same behaviour occurs when starting from bookmarks and from file explorer. The problem occurs with default config file.

Tried with MP3 and had the same problem. The problem may be with other codecs as well but I have not tried it so extensively.

If I set my Gigabeat F20 touchpad sensitivity to High, the touchpad and all buttons stop working - except for the long POWER action which shuts down in the normal manner.

I then need to reset settings on boot (or connect to a PC and edit them) to restore usability.

If other owners could try this out, I'd be interested - it may be that I have a stuck button under the touchpad, of course.

r29445 introduced problems with screendump on sansa e200 and e200v2 (and possibly more). Screendump works properly with r29444.

Steps to reproduce:

1. delete or backup existing .rockbox directory
2. install r29445 (or later)
3. reboot
4. navigate to System → Debug (Keep Out!) → Screendump and press select to enable
5. attach USB cable to trigger screendump

On e200, this results in:
*PANIC*
Stkov usb (0)

on e200v2, this results in a deadlock - no keypad response - backlight & button light never timeout. Upon reboot, multiple dump files exist.

On e200v2 only, when dircache is disabled, screendump will function properly.

Rockbox already exists for several years (fortunately), however it doesn't include a contacts list plugin by default, most likely because no one had coded one until now. As it's something that sometimes becomes handy, I decided to write my own, and as it's a simple enough plugin I've written it in LUA, to serve the purpose of a contacts plugin, to have a working example of a LUA plugin (that is not a game) and to explore the (im)possibilities of the LUA interpreter of Rockbox.

So this task will handle the development of a contacts plugin. Attached goes a BETA (but already very complete) version of the plugin. Just copy to your device (any location) and "play" the file.
The database where the contacts are stored is located at the root of your player, in a file called contacts.txt. The name and location of this file is subject to change in future versions, but the way contents are stored will probably keep being the same, so you can start adding your contacts (you can edit the file in the PC as long as you keep the format valid for LUA interpretation).

Key features (already implemented):
- View first, middle and last name of the contacts just after you open the plugin (fixed name order)
- Add contacts (lots of fields, I won't be adding more for now)
- Delete contacts (permanently and without confirmation, take care)
- View contact fields (after selecting it in the menu)
- View specific fields in their own screen (where you can also clear and, in the future, edit them)
- (Should be) Compatible with any Rockbox target that interprets LUA because the interface is entirely made of standard RB menus
- Works (at least) on my iPod Nano 2nd Gen
- Wonderful LACK OF warranty that it will work or that the plugin won't delete your contacts accidentally. Use keeping in mind this is a BETA version

To be implemented (for sure):
- Edit contacts
To be implemented (when I have time):
- Order the way names are displayed (e.g. first→middle→last to last→first→middle)
- Search for contacts by inputing part of any of the fields content
- Order contacts by categories (that's why there's a "Category" field on them)
To be implemented (if my programming skills allow it):
- Associate a image file to a contact, which will be shown when the contact is selected (and if someone codes it, why not a pictureflow of contacts?)
- Import and export contacts as vCards
- More configurable settings

Another additional note is that the current code of the plugin is not in agreement with the Rockbox coding style guidelines, I've tried to keep the number of chars in each line under 80, but there are lines where this is false. Also, the tabs are double-space instead of four spaces. This will be corrected when I finish the plugin.

Please test on your player and share the results, as well as any bugs or suggestions you might find.

Hi, this is a new codec based on the SC68 library
by Benjamin Gerard (sc68.atari.org).

Revision: 29484
Tested on: Sansa Fuze v2

Features:

1. 44 Khz Stereo sound.
2. Supports sc68 and sndh files.
3. Support for multi track and single track files.
4. Metadata parsing.
5. Fade out support.

** This codec needs the sc68 Replay folder to work, just put it in the root of
your player. you can find one here: http://aminet.net/package.php?package=mus/play/sc68.lha

Notes:

1.  This is a beta codec, some (big) songs may cause rockbox to crash.
2.  When compiling the sc68 library i had a lot of dependencies errors with
     missing includes.  It is compiling fine now on the vmware image, but not in cygwin.
     I still have to find the problem with that.
3.  Some songs doesn't work, specially some big sndh files.  I'm still working on it.
4.  Seek support is broken, i'm working on it.

Please feel free to make any comment or suggestion.

Split out from  FS#11748 .

This patch adds an option to prevent rewinding to the beginning of a track to avoid losing the current playback and resume position by accidentally pressing the Left key. Instead, Left always directly skips back to the previous track. This behavior can be enabled for all tracks or only for those tracks that can be autoresumed on automatic track change (which already is separately configurable).

I'm dropping this patch here for now because I see little chance right now of this being accepted into the trunk. Some developers have complained about the considerable configuration complexity of autoresume as it is, and although this additional behavior can be convenient, there is no ultimate need for it because the resume position prior to the rewind to 0:00 is preserved as long as another skip occurs within the first 15 seconds of the rewound track's playback (for example, by pressing Left again to skip to the previous track).

This change was originally contributed by Dave Slusher in  FS#11748 . I just added the configuration logic.

Patch relative to r29484.

I didn't like that the "Backlight on first keypress" function ignores the first keypress no matter which key was pressed. For example, I want the volume keys to work normally even when the backlight is off (that is, they should turn on the backlight *and* change the volume).

This patch restricts "Backlight on first keypress" to certain buttons only. in other words, these buttons work normally only when the backlight is on; otherwise, they just turn on the backlight. As a proof of concept, it changes the Clip and Clip+ behavior to filter out only the Home key when the backlight is off, allowing the other keys to function normally.

It works by allowing button-target.h to define the buttons that are filtered by the "Backlight on first keypress" function. If left undefined, the function filters all buttons when the backlight is off, as in the status quo.

[EDIT: Clarified that there is no overlap with  FS#9305  - Context sensitive backlight on key press]

decode_packet in wmaprodec.c returns -1 almost immediately, most likely due to being passed corrupted data by the ASF parser, although I have not confirmed that to be the case. I've seen similar issues in WMA Std. Theres probably some ASF feature we do not correctly implement.

recent %Tl and %T changes need adding to the manual… didnt want to fiddle with the table.

The change is now that both those tags accept as their first param a label which links them.

%T(foo, 0,50,25,25, volup)
%?Tl(foo, 1)<helllo|goodbye>

So that conditional will only go true when that foo region is pressed. the label is optional on both, if it is missing on the %Tl then it acts as now (timeout since last press on anywhere on the screen)

The interface of my Sansa Fuze and the file transfer freeze randomly when transferring large amounts of data. If the player runs in Bootloader USB mode everything is fine.

I guess this could break the vfat file system, making this a nasty bug. Disabling Key and Mouseemulation did not help. As long as this isn't fixed, a solution would be to start the player in Bootloader USB mode by default. I don't know if this is possible though, since I don't know the the technical details of rockbox very well.

Beside that everything works just great, keep up the good word!

PS.: I'm using Debian with different kernels. I couldn't see any differences between different kernel versions regarding this issue. Intels Linux USB drivers and the Linux USB stack in general usually work excellent as far as I know, therefore I would blame it on rockbox (no offense :)).

I suspect this bug has appeared since r29333, r29341, r29342 but I'm not 100% sure, it worked fine a few days back.

When I delete a file it goes well, but after I delete a file after first switching to another application or to the Android main screen deleting a file locks the main screen, it also locks up for other Android native screens like the keyboard you get when you create a directory.

I use Android 2.1 on a Cowon D3 device.

3.7.1, r29372, tested on Sansa e270

The idea is that when connected via USB, devices with button/wheel lights will indicate disk activity using the light, similar to a USB flash drive.

This works, sort of.
One real problem has been encountered:
The calls to buttonlight_on() and _off() seem to override the backlight_timeout_plugged setting, preventing the backlight from shutting off when this is enabled.

EQ settings changed via Touchscreen WPS action setting_inc & setting_dec are not reflected in the sound output of the device even though they display having been changed in the menus. The changes are also not written to the main config file on disk so they do not "stick" after Rockbox has been rebooted.

example syntax to toggle EQ on/off (display DOES get toggled):
%T(148,520,54,46,setting_dec,eq enabled)
%T(148,520,54,46,&setting_inc,eq enabled)
%xl(E,eq.bmp,0,0)
%V(148,520,54,46,-)
%?St(eq enabled)<%xd(E)|>

I'm not sure if this problem is specific to Android or if the problem applies to all targets.
APK Build: Feb 4, 2011

Bomberman like game with ai.
Not finished yet - lots of bugs and things to be done are known :)
Tested on Cowon D2 and also on some simulators with the same screen size (will work on other screen sizes too, but not now).
Somebody test it on iPod Video and on Zen Vision:M please.
Any suggestions greatly appreciated!
Hope the patch will work…

While the database initialisation is running, the tagcache queue can overflow due to system broadcast messages. This can be seen by running a simulator (it will crash with KERNEL_ASSERT after a while) or on a target by enabling KERNEL_OBJECT_CHECKS, then initialising the database and repeatedly connecting/disconnecting a charger.

The same problem may well happen with other queues (dircache, for example).

I got no SD-Card support for my E-250 after boot into USB mode.
I plug in my powered off player into usb and only have access to internal storage.

If i plug in my player booted up there is no problem.

I am using daily build r29174-110131.

When plugging in an AC USB charger, the ipod shows rockbox's disk mode instead of just changing the "external power" icon. Is it possible to make it detect if a charger is connected, or an usb host (for example, a computer)?

Doing the same test (with the same charger) on an ipod color/4g shows the expected result (not going to usb mode, just a charger icon appears)

[EDIT: Attached patch for experimenting with AS3543 settings.]

When playing back audio on a Sansa ClipV2 player, there is a regular background noise that’s audible with sensitive headphones and that’s quite annoying during quite music passages. The background noise is a hissing sound that repeats about 4 times per second. The noise can be heard when there is no disk activity and even at very low volume or when playback is muted. It stops as soon as audio is paused.

The noise is not present in the original firmware (OF).

This is a long-known issue, but hasn’t been formally tracked before. It is related to FS#11907, but different in that the background noise is present when there’s no disk (SD) activity. However, I did have the impression that disk activity intensifies the noise.

This item serves to collect the various approaches people have tried to eliminate the noise, and ideas for future exploration.

I ran a series of experiments on the assumption that the audio hardware is misconfigured is some way. I worked through various settings of the AS3543 component based on its datasheet. Here is what I have tried; but nothing helped to eliminate the noise:

* Higher-quality audio settings as proposed in  FS#11304  (AUDIOSET2_HPH_QUALITY_HIGH,
Disabled DAC gain control
Bypassed mixer and disabled mixer gain control (HPH_OUT_R_HP_OUT_DAC, AUDIOSET2_AGC_off,
Mute SDI data
Enable and control DAC attenuation
Disable common mode buffer (phantom ground)
Disabled various unused mixer components (AUDIOSET3_MICMIX_off, AUDIOSET3_ADCMIX_off,
Used external clock source for DAC
Enable headphone detection
Resetting all reserved audio registers to 0

[EDIT: I have attached a patch that allows experimenting with these settings by uncommenting the relevant source lines at compile time or extending the provided debug function to toggle the setting at run time.]

Possible next steps (suggested by various people on IRC):

* As the noise is not present on the other AMSv2 targets (Clip+, FuzeV2), a dump of the AS3543 settings (as3514_regs[] array) on these targets would be helpful. I have attached a patch that adds a debug-menu function for doing this (needs a logf build).

* Someone with a JTAG could read the AS3543 configuration set by the OF.

* The issue could be unrelated to the AS3543; it could be a power-management or frequency-scaling issue.

Also attached: A dump of as3514_regs[] (logf.txt; all values in
I’ve removed the patch to dump these settings; see a later comment in this task for a more up-to-date patch to do this.]

Other ideas?

Problem found in versions r29044-110113 to r29143-110126. I could not test 3.7.1, because it did not recognize my 16 GB Transcend flash card (fixed in above versions).

At the beginning of tracks and during rebuffering of longer tracks there is a short humming sound (like a bumblebee) mixed with a fast sequence of random high frequency tones. The sound differs as a function of data format and content. It is very homogeneous with WAV tracks (only humming) and different with lossy and lossless codecs. The same file encoded with FLAC and AAC leads to different short distortions. It is only audible for tracks with initial silence or very dynamic content, for example classical music with quiet passages or audio books. With sensitive headphones, this can be quite annoying.

The original firmware does not show this behavior!

It only happens while reading from the SD card, not from the internal storage.

Initially I thought this might be a CPU throttling issue. But now I think it might also be related to the controller driver.

There is a thread on Hydrogenaudio with independent confirmations of the issue:

http://www.hydrogenaudio.org/forums/index.php?showtopic=86306

If I can provide any additional information to help, please let me know.

I've hunted this down here is what I found out.

from
http://developer.android.com/reference/android/view/KeyEvent.Callback.html

public abstract boolean onKeyDown (int keyCode, KeyEvent event)
Since: API Level 1

Called when a key down event has occurred. If you return true, you can first call KeyEvent.startTracking() to have the framework track the event through its onKeyUp(int, KeyEvent) and also call your onKeyLongPress(int, KeyEvent) if it occurs.

We need to return true and call KeyEvent.startTracking() from /android/src/org/rockbox/RockboxFramebuffer.java then set the interrupt flag from /firmware/target/hosted/button-android.c and find out what is passed back after a key release and handle that. I may not be a great programmer but this looks like the ticket to removing the BUTTON_REL work around from /firmware/target/hosted/android/app/button-application.c

This is a preliminary patch to add the key maps needed to compile plugins for the android port. It is mostly complete.

You will need to change plugins=”yes” line 2790 of file /tools/configure but this breaks the sdl port.

Most plugins seem to work well some don’t, I have not tested all plugins yet but will start as soon I post this.

patch probably breaks some targets because of logo.c defaulting to a generic keymap which I changed “commented out” and added #error No keymaps defined! so the compiler will not just over look it. Let me know what breaks and I will try to fix it.

As we know, rockbox will use the information provided by "good" mp3 encoders (e.g. LAME) to ignore the extra padding that occurs at the beginning and end of each mp3 file, so that true gapless playback can occur. Unfortunately we do not always have the luxury of encoding our mp3 files in this way but we might still want true gapless playback. This patch compensates for the use of "dumb" mp3 encoders that do not record the necessary information for this feature.

In cases where it does not detect the proper header information to trim off the extra padding, it will optionally skip up to a full frame of silence (or near silence) at the beginning and end of each track (if the trimming is already specified, this patch does not do any additional trimming).

This can potentially eliminate up to a frame of "real" silence at the beginning or end of a track, but in terms of audibility, that would be completely unnoticeable (and it would only happen on these badly-encoded tracks), while the extra silence is an audible annoyance.

I have added an option to the Playback Settings menu so that the user can disable it if desired.

The attached patch implements a clean disk unmount by way of the following changes:

Patch 1: Allow disk_unmount_all to close all files and flush dirty buffers when unmounting a filesystem. (Before, we've been calling disk_unmount, which does not flush buffers because it's written to handle user-ejected storage media that aren't accessible any more.)

Patch 2: Call disk_unmount_all in the power-down and reboot paths.

Patch 3: Fix write to detect a bad file handle.

(Split out from FS#11877, in which I first theorized that an unclean filesystem may be responsible for some filesystem corruption I'm seeing, but which turned out to be a deeper problem. Related to r28693 /  FS#11774 , in which we introduced disk unmounting before entering USB mode.)

Various users on IRC recently reported cases of filesystem corruption. I have seen them as well, especially when using USB mode (I'm using a Sansa ClipV2, USB-enabled through  FS#11664 ).

One strangeness I've experienced is that when my system has detected filesystem corruption, it is often enough to remove the player from USB and then replug it, without repairing the filesystem and without rebooting Rockbox; on the next USB mount, the filesystem is clean. This might indicate that some buffer is flushed too late for the USB host to see.

[EDIT: Removed previously attached patch, which is now tracked separately as FS#11883.]

This appears to happen only on the simulator, as of r29012.

Fill a directory with, say, some .s3m files and .mod files. Mikmod plugin chokes on calloc (virtch.c, line 1227) during MikMod_Init() sequence.

Remove the .mod files and the plugin loads and works properly.

Reverting the change made to viewers.config in r29012 seems to fix this. I'm guessing the problem is somehow related to the way mod is both playable and viewable, but there's nothing obviously wrong with viewers.config that I can see. Maybe the buffers are getting screwed up somewhere in filetypes.c?

I have written a basic flashcard program for LUA and am attaching source code and an example data file. I am using a Sansa Clip+ so YMMV. It uses ANKI format text files which are tab delimited txt. You may use UTF8 for the flashcard if you have your device set as such. To use, save the two included text files in the same directory and run. The card data file, Russian.txt, is a typically UTF8 encoded text file exported straight from ANKI with no modifications. I am using a size 8-fixed font in the screen shots.

Things I would like to see done:

1. Making the code more generic to run on all rockbox platforms.

2. If someone would tell me how to play vorbis files from LUA on a clip+, I might be able to implement playing the vocabulary words as they are displayed on the device. I am already parsing the audio file names from the database, but I need a function to play them.

3. If LUA/Rockbox supported SQLite, It might be possible to read and write native ANKI database with scheduling information. This would facilitate programming of advanced flashcard scheduling for efficient learning.

4. A menu to select different databases.

Looking forward to feedback!

This patch adds a frequency response graph below the equalizer's controls, making it an EQ that is actually "graphical".

I'm still not sure about the accuracy of the represented curve, in particular the Q factor on the peaking filters seems to have an effect opposite to the expected, though the equations are taken from the same "audio EQ cookbook" the equalizer is based on, any help is appreciated!

The user interface is still incomplete, I want to add proper tags on the axes and bars. I also thought about re-enabling the theme on this screen (why is it disabled?) and change the behavior of the "right" button, making it consistent with other menus.

Tested on a Sansa e200.

r28936, sim build for iriver H120, fresh installation folder, i.e. no file “config.cfg”

I modified the function “sim_open” to ouput what files it’s opening, and got the following output (see attached text file). Note that there are files “-.kbd”, “-.sbs” and “-.rsbs”. I think these files should not be opened, even tried.

I've tried a dozen of builds around, and it seems that the new touchscreen on D2+ is not working properly - there're wild distortions (sometimes it's possible to press a button on lower bottom of the panel, but usually it's to no effect at all) at the edges of panel - i have to press almost on the edge of panel in order to tap the buttons, for instance in this (http://themes.rockbox.org/index.php?themeid=1146&target=cowond2) theme.

Version: r28861
Used before: r26706

Hello,

with r28861the touchscreen works with glitches.
When I touch a line-item , the system sometimes don't react or the line selector just "twinkle".

My conjecture:
It has somethin to do with the new "kinetic-scroll"-feature, because after a little kinetic-scroll the touch become precise.

(And yes, I've done a calibration: no effect)

This patch applies to the tools used to generate voice files and talk clips. It adds basic support for the free SVox Pico speech synthesizer, which is the default speech system on Android phones, and is also available on Linux and Windows. Support for this synthesizer is very basic, because the pico2wave utility used to generate wav files of synthesized speech lacks the ability to set speed, pitch, volume, etc. This patch has so far only been tested for English, although several other languages are supported by the synthesizer. Note that you will need the SVox Pico synthesizer installed on your system. On Ubuntu 10.10 and most recent Debian-based systems, installing libttspico-utils should automatically pull down the correct files. This patch hasn't been tested on Windows, but it should work if pico2wave.exe is in your path.

To build voice files using SVox Pico, apply this patch and run

tools/configure –type=AV

Then select your target from the list. The rest of the defaults should be fine, but be sure to type "p" when the script asks for the TTS engine to use. Then run

make voice

and copy the .voice file into .rockbox/langs. The next time you start Rockbox, you should hear your voice prompts spoken using SVox Pico.

To generate talk clips for filenames and directories using SVox Pico, apply the patch and run

tools/voice.pl -C -s=pico -S= -e=rbspeexenc -E= <directory you want spoken>

Your talk files will be generated recursively in the directory you specify. All _dirname.talk and .talk files that correspond to individual files will be generated, with the exception of the _dirname.talk file for the top level directory you specified.

Please test this patch and provide any feedback you have. Thanks.

When a WPS defines a touch area combining %T and setting_inc or setting_dec, although the themesite parser does not show any problems and allows the theme to be loaded normally, the themesite doesn't display the theme.

This patch modifies the CPU and peripheral bus clocks to hopefully gain some battery life. With this patch the CPU frequency can be either 31 or 186Mhz and the pclk is boosted from 31 to 62 Mhz while the CPU is boosted. The power draw of the CPU is proportional to the clock frequency and setting the frequency at or below what is required for playback keeps the power usage to a minimum because boosting to a frequency below 200Mhz is inexpensive. (Keeping the boosted CPU frequency below 200Mhz eliminates the need to wait for a voltage rise.)

I would appreciate feedback on battery life if anyone has the patience to run a battery bench.

Work in progress patch. Currently decodes audio but with some glitches. Has a small mountain of debug code included.

The basic idea is to rearrange the D filter coefficients in the synthesis filter so that pairs of them are used sequentially. This is not easy because the taps need to be loaded in the seemingly random order needed by the audio samples. However, this rearrangement seems to be possible:

0 1 2 3 4 5 6 7 (original sequence)
0 2 1 3 4 6 5 7 (new sequence)

The complication is that the code assumes that it can start a new filter at any offset, even odd ones, which means each and every filter needs to be rewritten 4 times, one for each of the 4 possible alignments. This patch does that.

Once I'm certain that it works, I intend to convert the D coefficients to packed 16 bit values, then use packed 16 bit multiply instructions on ARMv5E+. This should lead to a small speed up on armv4 (just because ldm instructions can be used instead of ldr) and a very large speed up on arm9E and arm11 (because packed multiplies are tremendously faster and much easier to pipeline).

URGENT/HIGH PRIORITY: Rockbox Firmware 3.7 installed with iRiver H300 1.29J.

Charging when in Rockbox mode (player switched on):

When Rockbox is running and the charger is plugged in, Rockbox can be seen charging the battery in the top left hand corner. When it is fully charged, it shows a full battery.

Charging when iRiver is powered off (player switched off):

When the charger is plugged in, the iRiver begins charging in Original Firmware mode. This is okay as the player charges correctly until Complete.

Booting into OF mode, shows a full battery charge so I can be sure it is fully charged.

However, boot back into Rockbox mode and Rockbox seems to be misreporting the battery charge as depleted - I say misreporting because at this point I know it is actually full/complete. (Booting back into OF mode would also confirm again at this point that there is indeed a full battery charge).

But run Rockbox 3.7 and after a few minutes, a false message - "Low Battery - Shutting Down" appears, after which Rockbox powers off.

I know this is inccorect, because if the battery was so low in OF, the iRiver OF would not even allow you to attempt to power back on (instead it would display a "Low Battery" picture on the display), but I can boot back into OF mode easily with no problems even after this message from Rockbox, again the OF shows a full battery and I can run it for hours with no problem so I know somewhere here there must be a miscommunication/misreading from the battery charge to the Rockbox 3.7 firmware.

Have tested this a number of times to ensure it is a fault and yes it presents itself everytime.

Patch against r28560.

Adds options for displaying pitches according to key (for transposing instruments) and “mixed” accidentals a la Korg (C#, Eb, F#, G#, Bb).

I’d also like to add some kind of support for alternate temperaments (perhaps even just intonation), however this isn’t trivial and I probably won’t undertake the project unless some interest is expressed.

This is the warning text I get. We should probably update the syntax before it get broken.

I think I have experienced a bug in 3.7+ builds with WPS themes related to %Vf.
If you put the %Vf on a new line, the following text is displayed, then cleared, but only if its a scrolling line, if the first line is static it is displayed properly, and subsequent lines are also displayed properly even if they are scrolling

example:

%Vl(b,0,108,176,60,1)
%Vf(999999)
%s%ac%?Ia<%Ia|>
%s%ac%?It<%It|%Fn>

artist is displayed briefly then cleared, if you take out %s artist is displayed properly, if you put the %Vf on the same line with %vl artist is displayed properly with scrolling, if you put a static text line before the first %s line then all lines are displayed properly.

so my quick fix is to just move the %vf on the line with %vl, but this bug probalby breaks many WPS, also this worked before 3.7, not sure when it stopped working. Tested this bug with latest build:r28534-101108 and 3.7 release sansa e200 v1. (also with latest e200 simulator)

this bug was not in builds up to or prior to: r27944-100830

r28529

This patch adds a new library that creates a calculator-like keyboard for easy number entry as an alternative to the on-screen keyboard. A lot of the code for drawing the buttons was taken from the calculator plugin.

Tested on the e200.

r28528

This adds a bitmap to be shown as the output of the 3 modes of the calculator, similar to the color-codes on the color targets, except that it is a static image for the greyscale targets. Might as well use the screen space for something.

Hi!

I’ve found very important bug in Rockbox 3.7, witch my be dangerous for both the player and the memory card (if present).
It turned out that Rockbox doesn’t react to very low battery level while voice or FM radio is recorded. It causes damage to the recorded file when finally hardware falls due to lack of energy. This corrupted file is absolutely unreadable.

sometimes when i click on next(or previous) button a couple of times , rockbox gets stuck and then anfter 3 or 4 secs ,it restarts .then when loaded the battery is empty.
i am not sure if this is a rockbox related issue or hardware realated cause i use my ipod for file transfer mainly .and this issue existed from version 3.3 till now( i cont know or remember about before that).

is there a way that i can somehow debug (trace) this issue?

This patch resorts the v-array within mpc’s synthesis filter. Through this data is placed more locally for the performance critical function mpc_decoder_windowing_D() and allows ldm-usage in the asm’ed parts.

This first patch does work for simulation but not for ARM or CF builds. An update with more optimized ARM asm will follow, CF asm needs to be corrected by someone with knowledge on CF assembly.

The output is binary identical.

This adds a very simple way for themers to add some customisability to their themes without requiring the user to actually edit the skin files.

2 new tags are added:
%Sl(name, default, …) to configure a setting named "name" with the default value "default", the … is any amount (up to 32) of strings which are accepted values. The order here is the order to be used with the next tag.

%Sv(name) to get the value. If the users value isnt in the above list, or the setting file is missing the default value will be used… can be used with normal ?<> conditionals or %if() (both number and name should work)

For the user to actually use this he needs to create /.rockbox/wps/skinsettings.txt which has the same syntax as .cfg files. i.e "name: value" and #comment.

This first version is very stupid and loads the .txt file into every skin which has a least one %Sl(), but the final version will do this much smarterer. (Also these settings are static so the values should be loaded at parser time instead of runtime.)

Also a plugin could be made to dump the allowed values for the used theme (or all skins) to disk to make it easier.

Because there is no limit to what the settings could be, I'm hoping that defacto setting names will just happen, the theme site could help with this also. It isnt a big deal if theme A accepts different values for a setting than theme B though.

Lastly, I need to also add a simple way for yes/no type settings %?Sv(show aa)<%Cd> should be able to work… Actually, brain fart time… because the settings are loaded at parse time we could probably use the feature handling code to always only parse the correct branch which would save a bunch of skin buffer and render time.

This attempts to implement the idea in http://forums.rockbox.org/index.php?topic=25169.0 this only works for the Settings menu in the main menu.

With this patch, if you reenter the Settings menu, it shows the menu shown when you leave the menu just like when you return to the browser or the database.

On page 51, which is in Section 6.8, there is a table for keys/actions. The Key column is completely empty, though.

On page 77, in Section 11.1.1, the blackjack game plugin, there table is similarly broken. Same for BrickMania in Section 11.1.2. Chessbox, in section 11.1.4 has a similar problem with only the "direction keys" being in the table.
There are many more games with this problem.

This is for a manual I downloaded 2010-10-11.

Thank you for your attention.

at least in the 16bit lcd drivers, all functions which use transparency (or clear pixels) get the pixel colour from the backdrop image, completly ignoring the bg_pattern.

This isnt a problem except in skins where it is perfectly reasonable to want a background image for most of the screen but a solid colour for one or two viewports.

There is a tiny problem though, bg_pattern is set to LCD_DEFAULT_BG which is a valid colour, so we probably need to add a flag to the viewport struct to say if it should ignore the background image or not.
