00:00:06stevenmAh.. it ain't defined if LITTLE_ENDIAN is.. okay well I hope this works because I have no way of knowing

00:02:52austriancoderhi all
00:03:00austriancodersome news?
00:03:13stevenmShagnar, this uses some rather experimental stuff.. I will be very surprised if that produces proper sound, but let's hope
00:03:21stevenmaustriancoder, hello. what's up?
00:03:53Shagnarstevenm allright, i just wait till the player finished (~2min)
00:04:00austriancoderremote lcd stuff is finished to 90 % - wps still needs some coding
00:04:04stevenmShagnar, ok
00:13:44stevenmShagnar, lemme know how bad it sounds :(
00:14:00Shagnarwe'll see ;)
00:15:06Shagnarfor the Mi1.mid
00:15:17Shagnarlets have a look on the wave
00:15:34stevenm2:15 .. ?! woah
00:15:57Shagnarsounds nice
00:16:07Shagnarcan't hear any error
00:16:08stevenmsounds RIGHT Shagnar ?
00:16:15stevenmShagnar, are you sure this is the right .rock ?
00:16:17rasheroh boy
00:16:23stevenmdid it take longer last time ?
00:16:40rasherdoing pretty well
00:16:52Shagnarabout 02:20... started the excel-DB for the times today so i dunno... mom i'll check a second time
00:17:25stevenmShagnar, unbelievable. That was like, the most stressful 18 hours of my life
00:17:38stevenm(not really but STILL)
00:17:42stevenmbah the thing actually worked
00:17:55stevenmand I hadn't actually removed the getSample() call.. just put the code IN it
00:18:08stevenmit's inline though, if that makes it less worse
00:18:08Shagnarin /viewers
00:18:18Shagnarits the right one (the latest)
00:18:23Shagnarone moment ;)
00:18:42stevenmmaybe I uploaded the wrong copy or something
00:18:50Shagnarcopied in /viewers <= right, yes?
00:19:01stevenmShagnar, right
00:19:22stevenmlooks like I uploaded what I built.. and it looks like latest build.. and I did remember to put it in ../pub ..
00:19:37preglowstart embedding build dates in the plugin :P
00:19:43Shagnarand i don't have to restart the player to make the new version affect?
00:19:59Shagnarsounds like a good idea, preglow
00:20:05stevenmpreglow, yea I was considering like, current time or something, just not sure how to automate
00:20:28stevenmmidi file is 1:35
00:20:38***Saving seen data "./dancer.seen"
00:20:42Shagnarmiditest is 1:34
00:20:50stevenmal right
00:21:05stevenmthat's 67%
00:21:18stevenmbeats the 50% without the endian stuff
00:21:57 Part LinusN
00:21:58stevenmnow I gotta go thru and remove the getSample CALL and actually replace it with the code.. possibly change the output buffer from chars to ints.. faster
00:22:06rasherstevenm: make it output the time of build and the time-to-decode to a file :)
00:22:21Shagnarso you're shure i run the right version?
00:22:30preglowstevenm: if you're just replacing all getsample calls with the getsample code, just declare getsample inline instead
00:22:45stevenmpreglow, yes that's waht it is now. and all it is is a return statement
00:23:02stevenmShagnar, let me change the startup text, just in case :)
00:23:19Shagnaror just a number at the end of the text

05:02:03eVoxanyone out there?
05:02:29eVoxive got a problem with my ihp120
05:03:22eVoxit got plugged into a phone charger...and despite the charger being the same polarity and less power, the ihp is messed up
05:03:59RickThat was silly ;P
05:04:04*Rick wonders how it messed up
05:04:13eVoxthe screen is garbled (similar to 'artifacting' on overheating video cards), but it will boot up and respond to button commands (but u gatta hold the buttons for 3x as long as normal)
05:04:32RickSounds like it was fried or something
05:04:40Rickdoes the remote work?
05:04:46eVoxyeah i went to charge it for a trip to atlanta tomarrow, and later went looking for my phone charge and had an 'ohhhhhhhhhh shit' moment
05:05:28eVoxits still working as a harddrive (via computer connection), and the radio works, but the menus are fubar and it wont actually play mp3s
05:05:43RickCan't help you there... :/
05:05:46Rickmaybe someone else could
05:05:54eVoxis there a reset to safe mode thing? like on dell jukebox's?
05:06:05Rickeh, there's a reset
05:06:10Rickit's not like a safemode
05:06:21eVoxive reset it like 400 tiems
05:06:24RickI doubt that would have any effect
05:06:30RickUnless the firmware somehow fucked up
05:06:52eVoxive *tried* updating the firmware but its hard with garbled menus
05:07:42eVoxon the 'general' menu, is update firmware the 2nd one up from the bottom?
05:07:50Ricklet me check
05:08:07Rickwhat version do you have?
05:08:23eVoxthe most current
05:08:35eVoxthe standard...not rockbox
05:08:51Rickin the newer firmware
05:08:53Rickthere's a format option
05:09:39eVoxwhat are u getting at?
05:09:50Rickif your firmware is newer
05:09:57Rickthe firmware upgrade is 3rd from bottom
05:09:58Ricknot 2nd
05:10:05Rick(the last is format instead of db scan)
05:10:18eVoxwhats 2nd up?
05:10:23eVoxdb scan?
05:10:24Rickdb scan
05:10:46Rickthen you want to click
05:11:27eVoxwhats 3rd up on the old one?
05:11:42eVoxcuz i have some garbled screen idk what it says
05:12:08eVoxi think upgrading with the picture of the ihp like on the boot screen
05:12:16eVoxif i squint real hard

05:16:52eVoxand is still fubar on reset do you take these things apart? the micro allen wrench screws?
05:17:30RickI forget the name
05:21:28eVoxdo you want to buy a paperweight?
05:25:35RickNot really.
05:28:47eVoxin the newest there a set of horizontal scrolling icons when u press the main button in?
05:29:04RickI don't know
05:29:09RickI don't have the latest
05:29:18Rickas I have rockbox on it
05:29:38eVoxhow is rockbox
05:29:47eVoxi check the site every couple of days
05:29:56eVoxits is fully functional for playing mp3s?
05:31:47eVoxdoes it play mp3s?

10:08:59amiconnMisconfiguration is usually not the router's fault
10:09:40austriancoderit was the fault of the people bevore us
10:10:08ashridaheh? resetting a cisco router isn't that hard, provided you've got a console cable...
10:10:51ashridahreset it, break the bootup, change a flag so it doesn't autoload the config, reboot, ignore the config, reset the flag so it'll load your config once you've written it.

11:34:59[IDC]Dragonamiconn: you've probably been the first to hear it play
11:35:12amiconnI don't think so
11:35:33amiconnYou reported the FM playing already, when my SP did not yet.
11:35:41[IDC]Dragonbecouse of the MMC part, I thought
11:35:55amiconnSmall wonder - the FM uses the same MAS as the recorder, while the SP doesn't
11:36:08[IDC]DragonFM was before mp3?
11:36:18[IDC]Dragonthis doesn't count...
11:36:41Lynx_LinusN: congrats for mp3 playback :)
11:36:53amiconnYes, FM was before mp3, at least with the Samsung tuner, but I don't mean that either
11:37:11ashridahin actual news, the human race was doomed to extinction today, as the robot revolt turned violent.
11:37:25amiconn[IDC]Dragon: After MMC was working, you almost instantly reported mp3 playback sort-of working, while my SP kept silent
11:37:46amiconnI had to adapt the configuration memory addresses first
11:39:07bobTHCi'm agree with dwihno, a new item in the frontpage news section is mandatory for this kind of milestone, imho
11:39:36preglowlet's wait until it doesn't glitch, at least ;)
11:41:13Rickhas anyone looked at iriver's fm?
11:41:44amiconnaustriancoder: If you're looking for another driver to write, you could write an i2c driver for the fm radio chip
11:42:24amiconnWhen this is done, the rest should be fairly easy. The iRiver uses the same philips radio chip as the newer Ondio FM's

15:59:54bobTHCHCl > the PluginRockboy is announce to be compatible with recorder ? what's the reality ?
16:01:09HClbobTHC: it works. very slowly.
16:01:46bobTHC@5% of RT ?
16:01:52HClsomething like that
16:01:55HCl6fps iirc
16:02:00preglowyo, hcl
16:02:02HClfaster than iriver at 11mhz
16:02:04HClbut not fast enough
16:02:14preglowi think you can pretty much forget dynarec being feasible on h1x0
16:02:21preglowthe ram is so incredibly slow
16:02:33preglowso _INCREDIBLY_ slow
16:03:10HCli think its better to focus on an asm cpu core
16:03:17preglowi agree
16:03:20HCland asm versions of the functions that were converted to asm on x86
16:03:25preglowand using iram for important data
16:03:55preglowi wish a time buble just enveloped me and allowed me to code rockbox for a couple of months straight
16:04:50HCl :P
16:04:54HClits called summer vacation :P
16:05:46preglowi'll have to get a job :/
16:06:22preglowit's good bye to long, lovely, good summer vacations for me
16:06:38HCl :X
16:12:03tvelocity[away]hire yourself to develop rockbox
16:12:21tvelocity[away]and with the money you earn you can pay for your hired developer (yourself)
16:17:21amiconnHCl: I still think dynarec would make a performance boost, even on iriver, and compared to an asm cpu core. The slow ram performance will most likely hit an interpretive cpu core by the roughly same amount
16:17:54 Quit tedboer (Remote closed the connection)
16:18:06bobTHCpreglow > and as tvelocity[away] is a good guy he donate monthly the tantamount to your wage ;)
16:18:20preglowi'm really quite convinced an asm cpu core will be faster
16:18:46preglowtvelocity[away]: hey, i like where this i going, shall we say 100$ bucks an hour?
16:19:15*tvelocity[away] hides in a corner
16:21:00***Saving seen data "./dancer.seen"
16:21:10amiconnpreglow: Why? Part of the asm cpu core code might be in iram, but it still needs to read the z80 instructions from sdram. Z80 instructions are usually single bytes, so that might be even slower than running m68k code from sdram (and having it in the icache for loops)
16:26:35HCleither way.
16:26:38HClwe can do both.
16:26:46HCldynarec can be integrated into an assembly cpu core
16:26:59HCland it won't be up to full speed without one anyways
16:27:07HClso its better to write the assembly cpu core first
16:27:13HClthen if thats not fast enough, add dynarec
16:28:34HClat the moment i'm more interested in on the fly playlist creation
16:28:56preglowafter seeing how huge a frigging boost i got from adding some table data to my imdct_l routine, i realized how bloody important it is
16:29:10preglowi even use movem for the data in question, so should be fast also in sdram
16:29:11preglowbut no
16:29:42preglowmost of the interpreter core should fit in the code cache
16:29:51preglowso don't use iram for code
16:30:13preglowhow much ram does the gameboy have?
16:30:42amiconnUp to 4 meg are possible (mostly rom)
16:30:51preglowyeah, i meant ram
16:31:10preglowor can carts add extra ram as well?
16:32:38amiconnI'm not that much into gameboy hardware, but I think this is possible
16:33:24amiconnI don't understand why you're explicitly asking for ram though
16:33:39preglowwell, if it's very little, just stuff it in iram
16:33:51preglowz80 has few registers, so it'll be accessed a lot
16:34:07preglowdoing byte and word accesses on a coldfire is slow enough as it is
16:34:32HClit can only have 16bits of adress space
16:34:34HClat the same time
16:34:43HClof which the lower 8k are rom
16:34:44preglowwhat about bank switching?
16:34:53preglowdoes it do that?
16:35:02amiconnDo you propose copy-on-bankswitch? Now _that_ may be slow
16:35:31preglowno, i don't
16:35:32HCli meant < 0x8000 are rom o.o
16:35:44HClthats 32kb..
16:36:19HClit has two banks
16:36:36HClwait, maybe i'm wrong about that o.o
16:37:15HCleither way, everything below 0x8000 in gb address space is rom
16:37:41HCl64kb of adress space in total
16:39:21HClpreglow: how fast is mp3 now?
16:40:20preglowvery fast, once i get linus' as well as my last changes in iram at the same time
16:40:29preglowapproaching 300% realtime
16:41:15HClat 120mhz, i assume?
16:41:19HClwhat about 48mhz?
16:41:23preglowclose to 100%
16:41:33HClis that enough?
16:41:46preglowoh yes
16:42:50MoosCamaropreglow: good progress
16:42:52Shagnarwill linus' mp3-play-test be implemented like the /sample.wav test?
16:43:17preglowwho knows
16:43:18preglowi doubt it
16:43:23HClpreglow: what about 320bps ?
16:43:43preglowHCl: that's what i'm talking about

18:36:03preglowi must be a masochist
18:36:37preglowi'm actually itching to try optimizing the mdct in tremor
18:36:56 Part lImbus
18:37:05preglowit's actually quite emac friendly
18:38:14preglowi do wonder how the PROD32 functions will do, though, the top bit is automatically shifted away by the multiplier
18:39:30preglowif that bit is actually used, we've got a problem
18:53:42HCli thought markun was saying something about how the top 32bits being the most important ones..
18:53:53HCland him saying about how we couldn't use the emac for that cause of it
18:53:59HCli might be wrong though
18:54:01preglowof course they are
18:54:57preglowall my imdct_l opts use the top bits with emac instructions
18:55:02preglowso he is quite obviously wrong
18:55:28preglowi'd be happy to tell him how to use the emac in such a way, just have him ask
18:56:05preglowvorbis optimizations don't look to be too hard, they often use a fixed point format that is equivalent to what the emac unit uses internally

20:31:04stevenmHCl, thanks
20:31:05amiconnHCl: The MAS .wav codec should allow playing .mods as well
20:31:17rasherI'm probably not going to be of much help
20:31:24HClamiconn: are mods low profile enough?
20:31:44amiconnThink so, at least the 4-channel protracker (-derivates)
20:32:12amiconnIf a stock 7 MHz AMiga is able to play them, an 11..12 MHz should as well
20:32:13HCltime for my timed midi run
20:32:39HClthe autodetection of rolo isn't working for me properly
20:33:01HClstevenm: it crashed.
20:33:09stevenmHCl, hmm? What it say?
20:33:29stevenmHCl, what's that? How far did it get in loading?
20:33:33muesli-yepp, got this in rockboy too
20:33:44HClit showed \<midifilename>
20:33:46HCland then it crashed
20:33:51HClmuesli-: mm?
20:33:57stevenmHCl, you have the patchset in .rockbox ?
20:34:15*HCl goes to get a paperclip
20:34:37muesli-HCl when i started super mario i got an error msg like this and the player hang up
20:34:37stevenmHCl, that is strange.
20:35:17HClit seems all plugins are broken
20:35:20HClat least rockboy too.
20:35:27stevenmHCl, ALL plugins ?
20:35:38HClwell, at least rockboy
20:35:51stevenmHCl, Ah, I see
20:36:05HCland yes
20:36:06HClall plugins
20:36:09HClminesweeper crashes too
20:36:22stevenmHCl, we tested midi last night and it ran fine.. and the only changes I made would have caused a crash on patch load
20:36:30stevenmTHAt is not good
20:36:48HCleven pong breaks
20:36:55HCli'm not gonna be able to test anything with current cvs
20:36:57stevenmall with the same error?
20:37:11stevenmLinusN, any ideas >
20:38:11HClcan someone explain/tell me why the rockbox logo on the remote is upside down?
20:39:06amiconnHCl: (crashing plugins) Seems your plugins don't match your rockbox.iriver (plugin api mismatch), and the api version was not bumped
20:39:07rasherHCl: your build sounds brooooken
20:39:24HCli'll try to rebuild completely..
20:39:35HClbut as far as i know
20:39:37HCli already did
20:42:03rasheroh, no.. getting I0B as well
20:42:26rasheron a fresh build
20:42:47stevenmso, what happen ?
20:43:14rasherhaha, helloworld works... sortof
20:43:18stevenmSomething in recent CVS ?
20:43:56HCllinus changed the memory location thing recently...
20:43:57HCli think..
20:44:13stevenmHCl, yea I see that in the recent CVS.. would that affect plugins somehow?
20:44:18rashersounds like that could be it
20:44:22rashertry "helloworld" plugin
20:44:27rasherit outputs garbage
20:44:29HClhelloworld "works"
20:47:36t0mas-#define DRAMORIG 0x30000000
20:47:36t0mas+#define DRAMORIG 0x31000000
20:47:41t0mascan that be a problem?
20:47:43HClis there any way to revert certain files to the old version?
20:47:51t0mascheckout the old version?
20:48:08t0masI don't know the options out of the blue
20:48:14t0masnormally use a graphical client
20:48:33HCli'll just change everything back to the 3000..
20:48:36HClsee if it helps
20:48:37t0mascvs checkout -D date
20:48:51t0masyesterday might work?
20:49:36HClalready changed everything back by hand
20:49:56t0masok, is that working?
20:50:34stevenmchange of classes, back in 10 min
20:51:26LinusNall plugins must be compiled

20:56:40amiconnLinusN: Btw, what was the problem with the old sdram start address?
20:56:54*HCl is curious to that too.
20:57:51LinusNthe sdram was mirrored in an unfortunate manner
21:00:10LinusNbadness :-)
21:00:15*HCl wonders whether it causes/fixes his upside down rockbox logo on his remote..
21:00:32LinusNthe 32mb was suddenly two copies of the first 16mbytes
21:00:49HClhow'd that happen o.o

21:04:36HClk o.o
21:05:01HClum, steven
21:05:05HClit said could not load file
21:05:28*HCl stares at it saying "i hope this works"
21:05:47stevenmHCl, is there HD activity ?
21:06:14HCl1 minute 15 seconds passed, including the loading patches bit
21:06:20stevenmHCl, interesting, so it must be synthesizing. I wonder what though
21:06:28stevenmHCl, what file could it not load?
21:06:41HClum, i just clicked the select button on the midi file
21:07:18stevenmHCl, all right... I guess it looks like it is running. I am just curious, what specific error did you get?
21:07:18HCli'm just hoping it'll stop eventually o.o.
21:07:32HClcan't say, it went too fast, something with unable to load file
21:07:33stevenmHCl, at 120Mhz it should not take more than 2 and a half min
21:07:37HClthen it proceeded to load patches
21:07:42HCli forgot 120mhz
21:07:53stevenmHCl, it started NAMING patches?
21:08:03HClnaming? o.o.
21:08:13stevenmlike, started showing their names on the screen
21:08:34stevenmbecause it would have said "Error opening [something].pat" if it cannot find the patchset
21:08:40HClgonna start again
21:08:42HClno, not that
21:08:55HCl"Could not open file"
21:08:59stevenmHold on a sec
21:09:11HCland then it quickly says something about -7 and size
21:09:11 Quit webguest78 ("CGI:IRC (EOF)")
21:09:19HCl "/mi1.mid"
21:09:22HClit said that before everything
21:09:58 Nick tvelocity[away] is now known as tvelocity (
21:09:58stevenmHCl, -7 size is a .wav thing, that always happens with xxx2wav
21:10:27stevenmHCl, it says 'Could not open file" if the file descriptor for the .mid file is 0. I was under the impression that 0 means invalid
21:10:38stevenmHCl, so if it got changed to -1 or something, then no worries
21:10:39HClno, -1 means invalid
21:10:57stevenmHCl, ah, that explains it ... .. the sim version must be different
21:10:57HClokay, i didn't time this run though..
21:11:09HClit ended
21:11:12stevenmHCl, ah.. well you should (hopefully) get a .wav
21:11:16HCllet me try again and time
21:11:17stevenmmiditest.wav and it should be working
21:11:20stevenmHCl, thanks
21:11:36HCl9:11:28 starting time
21:13:09rasherstevenm: if you want to time, you can look at how battery_test does it .. it's super-easy
21:13:26stevenmrasher, will do
21:13:36HClexactly 2 minutes
21:13:40stevenmrasher, I just squashed a few shifts in this one, and precomputed a few things
21:13:43stevenmHCl, thanks
21:14:00rasherrb->get_current_tick() or something
21:14:01stevenmWow that is 78% realtime
21:14:06HClinteresting, the plugin fix also flipped my rockbox logo the way its supposed to be
21:14:09rasherjust subtract that from start/end, and you're good
21:14:14HClon the remote
21:14:27rasherthat's pretty crazy
21:14:51stevenmHCl, just out of curiosity.. the output file, miditest.wav, is it mangled or sounding ok?
21:14:56HClno idea
21:14:57amiconnstevenm: 0 is always a valid file descriptor, also for the simulator. It's just that you won't see fd == 0 on the sim very often.
21:14:58HCllet me play.
21:15:12stevenmamiconn, all right, will change
21:15:47stevenmamiconn, yea, it's -1 in other places.. I must have missed one here

21:17:45CtcpIgnored 1 channel CTCP requests in 0 seconds at the last flood
21:17:45*HCl nods
21:17:52stevenmI know this is not the best way of doing it because different parts of the file have different load
21:18:03stevenmbut it works for average and gauging if it got any faster
21:18:31stevenmnext I have my eyes set on the output buffer and the huge if statements, see if that can be sped up any
21:18:47lolo-laptopstevenm: do you think there is enough room for optimization to do midi playback in battery/heat feasible time?
21:18:54 Nick lolo-laptop is now known as lostlogi (~lostlogic@
21:18:55 Nick lostlogi is now known as lostlogic (~lostlogic@
21:19:19rasherI don't think heat will be a problem
21:19:22rasheror.. it won't
21:19:41stevenmlostlogic, I am hopeful. This is only optimization in C.. after nothing more can be done, I guess I can ask someone to help me optimize in ASM, like use emac, etc
21:19:43 Join ep0ch [0] (
21:19:50rashernot since we run the cpu at max 120mhz
21:20:04stevenmlostlogic, heat I don't think is a big deal because we decided 140Mhz was too hot.. so then 120Mhz is fine ?
21:20:27ep0chquick question, does writing to disk add much of an overhead?
21:20:32stevenmwe can always cut the sampling rate again :)
21:20:46t0masep0ch: yes
21:20:50t0masit slows things down
21:20:56stevenmt0mas, this thing writes once every 3000 samples
21:21:13stevenmt0mas, you think that causes too much slowdown ?
21:21:15HClyou cut sampling rate?
21:21:15rasherI ran my iriver for 5 hours straight at maximum cpu usage without overheating
21:21:17t0masdon't know
21:21:23ep0chso stevenm might be running at realtime with disk output off
21:21:25HClstevenm: how many times per second is that?
21:21:32stevenmHCl, yea right now it is at 22050Hz
21:21:35t0masep0ch: don't think so
21:21:43t0masstevenm: you can test it?
21:21:44stevenmwell let's see here. it writes every 3000 BYTES
21:21:47t0masjust remove diskwriting...
21:21:57stevenmHCl, you wanna do a test w/o writing?
21:22:00t0masand run it with a stopwatch next to it ;)
21:22:00HClthen yes. remove diskwriting
21:22:04HCldefinately :P
21:22:08*t0mas too :)
21:22:14stevenmHCl, all right, go to midi2wav.c
21:22:41stevenmComment out line 214
21:22:43t0masin plugins right?
21:23:07stevenmnah I was gonna say, comment out the write(...) call
21:23:09t0masbetter comment out the whole if...
21:23:30t0masor is that line I copyed needed?
21:23:36stevenmyea actually comment out everything in that loop but synthSample()
21:24:18stevenmI actually wanna change the buffer to ints so that we don't have all the register overhead than that
21:24:48stevenmand none of that crazy incrementing crap, just assign it and stuff. then it becomes faster.. worked for getsampe
21:25:09*HCl runs to get his chrger
21:26:09lostlogicwill this midi playing on a portable audio player be a first? I do not know of any others...
21:27:09ep0chanyone looking at DSP effects?
21:27:50*HCl forgot 120mhz again
21:28:02stevenmthere is no disk activity this time, right ?
21:28:24ep0chthere's a noise shapening plugin for foobar that would be damn nice in rockbox
21:28:27stevenmlostlogic, I guess it'd be pretty cool if it actually gets up to speed
21:28:58stevenmbtw I just subscribed to rockbox mail list.. sorry about the comments and code, etc. will fix
21:29:05stevenmcoding style/tabs
21:30:23HClnot realtime
21:30:38ep0chmore than realtime? ;)
21:30:46HClthats disappointing
21:30:52HClit only made a difference of 4 seconds? o.o
21:31:49stevenmHCl, I see.. did you comment out just the write or the whole outputBuffer[...] stuff too
21:32:01HCloutputbuffer stuff too.
21:32:11stevenmmaybe it is done in the background or something
21:32:24stevenmwell there is still ASM stuff.. plus stuff to be done in C

22:08:41amiconnThis PCM pass-through can only handle 44.1kHz 16 bit stereo, with no buffering
22:08:59preglowhahah, the plasma uses LONG DOUBLES
22:09:10rashersounds great
22:09:12preglowthe only float format gcc doesn't support emulating
22:09:16amiconn...and from the MAS' parallel port input, which is not connected in the archos boxes
22:09:36preglowamiconn: this'll be more flexible?

22:10:06preglowat least they weren't listed in the file i looked at
22:10:43amiconnAfaik, the Archos multimedia jukeboxes, also use the MAS for audio decoding, and obviously there was demand for PCM support
22:11:33amiconnSo archos developed their own PCM codec, which is said to be much more capable. Handling different sample frequencies, using buffering etc.
22:11:49amiconnWe *believe* that it also support serial transfers
22:11:59preglowa ton of code just for generating a sine table
22:12:20rasherpreglow: plasma?
22:12:40amiconnpreglow: If that's the only place were floats are used, the fix should be simple
22:12:51HCli really need to fix my icq so i can reach markun..
22:12:52preglowthe fix will be simple anyway
22:13:03preglowi just don't see why he doesn't use a precalced sine table in such a little plugin
22:13:16preglowif you use interpolation, you need very few points
22:13:30amiconnIirc it was for educational purposes
22:13:39stevenmwould it be possible to reverse engineer the firmware in the other models and see how the PCM codec works?
22:13:43preglow128 points with linear interpolation is sufficient for high fidelity audio use, so it's much, much more than adequate here
22:13:49amiconnOtherwise he could just have copied the sine table from cube.c
22:14:04amiconn...which is 1 degree resolution
22:14:32preglowif its educational i guess there's a point to it
22:14:41amiconnUnfortunately that one uses the odd fixed point format I once mentioned
22:14:59amiconn(divide by a power of 10 instead of a power of 2)
22:15:22preglowthere are no floats in the main loop
22:15:38preglowjust switching everything from 'long double' to 'double' should have this working on iriver as well
22:15:42*amiconn should really get up to full speed rockbox dev again
22:15:55preglowprovided someone code the grayscale lib for iriver as well, of course :V

22:24:09preglowamiconn: indeed
22:24:35preglowif you never use your backlight, that will be an issue
22:24:54stevenmI was showing my friend ajbrec w/ rockbox and video plugin. He has korean firmware on 3x0
22:25:02amiconnHowever, I know that it's possible to build colour LCDs that are readable with very little or no extra backlighting if the ambient light is strong enough
22:25:02t0maseh... the white colorlcd backlight uses more power than thow simple blue leds right?
22:25:05stevenmhe was very excited to say he was watching stargate on that at 8 fps

22:47:58HClwhat should the xxx_ be?
22:48:45t0masamiconn? I have that bmp thing working... and from plugins its easy to use the pluginbuffer... but when I do something in core... should I just declare a static image buffer? or are there other ways?
22:48:56amiconnWell, I didn't think about that yet. Maybe it should just be lcd_ for the core implementation as it is now
22:49:21HCllcd_ are using the same functions..
22:50:06amiconnt0mas: As I already said, my idea would be that the core module which actually uses the images does its own buffering (e.g. wps)
22:50:19t0masyeah, that's what I'm doing now
22:50:56amiconnHCl: The idea is to unify the graphics apis, so some work is required for the b&w archos lcd_ implementation as well
22:50:56t0masbut in wps I can just declare a simple unsigned char images[2560]... or do something intelligent.. problem: I don't know how to do it intelligent :P
22:51:20amiconnThere is no more intelligent way

22:56:41BiptoriaHow well did it play?
22:56:49rasherit didn't play well :)
22:57:03BiptoriaGet back to work then rasher
22:57:44amiconnHCl: I mean, for such displays like the archos (or iriver in b&w mode) one byte matches 8 pixels, and for iriver 4-grey it matches 4 pixels
22:57:51HClwhat about it..?
22:58:12amiconnSo if you manipulate whole blocks at once, this should definitely boost performance
22:58:33HClum. okay *still confused*
22:58:47HCli'll just try to implement that new api as lcd_* in lcd-h100.c, right?
22:59:13amiconnlcd_bitmap() does what I mean in the b&w implementation
22:59:20BiptoriaInstead of having the CPU piss around with lots of blocks, it pisses round with larger less blocks ?
22:59:27stevenmHey guys, does anyone mind if I commit all the midi code, or is anyone else messing with that?
22:59:35HCli say go ahead
22:59:52amiconnlcd_fillrect() simply re-uses lcd_bitmap(), which is way better than doing single pixels, but not yet optimal
22:59:54HClcvs is after all a concurrent versioning system.

23:13:25HClbut yea, i think its fast enough, and we can always just optimize it asap
23:13:34HClbut first
23:13:38HCli need to get my cat out of my lap

23:14:21Biptoriapoor thing
23:15:05Biptoriayou should of got a dog, you can sell them for more 2nd hand
23:15:21 Quit muesli- (No route to host)
23:15:25HCldogs drool, smell, and are too stupid to walk theirselves.
23:15:33ehntoowell, not always.
23:15:34HCland they don't clean theirselves either
23:15:36BiptoriaMuesli my main cereal
23:16:04HClamiconn: i should just create the lcd_* things of the new api for iriver, right?
23:16:08Tang_good night all
23:16:16BiptoriaI know a dog that walks it self, it only has 3 legs
23:16:39rashercat's are annoyingly independent
23:16:51Biptoriayeh, there gay
23:16:52Tang_i rather cats
23:17:03Tang_cause they are independants
23:17:08Tang_and curious
23:17:12Tang_unlike dogs
23:17:27amiconnHCl: yes
23:17:38BiptoriaAkk they want is food then they piss off for the rest of the day
23:17:40stevenmour hs physics teacher hated cats with all his being
23:17:53stevenmalways colliding an elephant with a cat
23:18:01stevenmcats, and his mother-in-law
23:18:14Biptoriawhats wrong with elephants
23:18:19Tang_i would want to know
23:18:30ehntootoo big, you can't shove an elephant in a cupboard when you get mad at them.
23:18:35Tang_if elephant always fall on their legs like cats
23:18:39stevenmThey have a lot of momentum when THROWN at a cat
23:19:03Tang_unfortunately no zoo directors let me try
23:19:16Tang_(time to go to bed i guess)
23:19:25HCli'll get on it as soon as people stop talking to me x.x;
23:19:36BiptoriaYeh im off aswell. love you HCI

23:20:19ehntooyou can stop smiling now.
23:20:26stevenmwoot! no more midi2wav.c warnings
23:20:50rasherthat's the first time in a while that iriver warning count has gone down :)
23:20:55stevenmeep.. there's one on normal target..
23:21:09stevenmand I know why too. I changed a parameter
23:21:15stevenmbut still.. I killed like, 9
23:21:35ehntooI see that. good work.
23:21:56stevenm:) thanks
23:22:09stevenmand I converted all the tab/space stuff and the comment style. that took a while
23:22:39HClwe need an astyle line on the wiki that people can use..
23:22:50stevenmfortunately mindlessly changing // to /* */ is only slightly less boring than listening to the guy praddle on about physics
23:25:10HClamiconn: what should the default mode be?
23:25:32HClthats not a valid mode :p
23:25:32amiconnsorry, wasn't directed to you
23:26:11HClwhat should it be?

23:28:26amiconnHCl: default mode should either be FG or SOLID

23:29:37ehntoohave a good period of nourishment ingestion.
23:29:41 Part stevenm ("Connection reset by beer.")
23:30:32HClamiconn: i could use a description on the wiki to how the mode affects each function..
23:30:51HCl_blit for example, does the mode get ignored there or what?
23:31:18 Join ashridah [0] (
23:32:17amiconnAh, hmm, I think I made that clear enough. The description of the function should tell you whether it uses the mode or not
23:32:18 Quit courtc (Connection timed out)
23:32:27 Join courtc [0] (
23:32:47amiconnBasically, all drawing function use the mode, with the exception of the non-b&w bitmap functions
23:33:30amiconnAll other functions (scrolling, updating, specials) do not.
23:33:48HCldidn't see that
23:33:48amiconnlcd_clear_display() counts as a drawing function in respect to that
23:34:58amiconnWell, lcd_clear_display() is a 'half'-drawing-function, in that it should use the background colour, but not the mode
23:36:20amiconnIt is debatable whether the xxx_blit() function is part of the graphics api at all. In fact, it's a low-level access function for the lcd that circumvents the normal graphics api...
23:36:51*amiconn realises he's talking too much and coding too little
23:38:02HCl :p
23:38:03amiconnrasher: Your stats are really great :-/ I'm the second-most talker (word count wise), while being around for far less time than Linus :-O
23:38:04*HCl works on stuff
23:39:32HCldoes anyone know how many intermediate grayscale settings the iriver lcd can have?
23:39:41HClor 8?
23:41:27preglowblack, white and two user definable
23:41:38preglowif that's what you meant :>
23:41:54preglowor do you mean how many levels of gray you can have?
23:42:02HClwell, i meant what you can set the user definable too
23:42:08HClbut i found some code of markun for that already
23:42:15preglowthe data sheet has that info
23:42:38HClamiconn: should i make dummy rgb functions for set_foreground etc
23:42:40HClor leave them out?
23:43:15amiconnNo rgb necessary for greyscale displays
23:43:44amiconnforeground and background should just use a single value for them
23:44:23amiconn(0..3 in case of iriver, with 0 == black and 3 == white, the 2 grey levels being equally spreaded)
23:45:13amiconnAh no, of course it should take 0..255
23:45:29amiconnThat's simple to convert anyway, just shift right by 6
23:47:12amiconnLinusN: Are you there?
23:48:23HClif something in mode complement draws on something, it should invert the foreground pixel if there is one, right?
23:49:36HClcan you explain the FG/BG mode?
23:49:56HClBG will only draw on background pixels(empty) and FG only on foreground pixels (already drawn pixels) ?
23:50:17HClshouldn't it be draw background pixels with current foreground colour?
23:50:36preglowehh? i thought fg and bg scheme was only used in text mode-ish stuff
23:50:51amiconnNo, foreground and background isn't related to what is already on the display, but what your to-be-drawn primitive looks like
23:51:03HCloh. right.
23:51:09amiconnpreglow: Text mode and 1-bit bitmaps
23:51:13HClso we only draw the fg that exists and the bg if exists
23:51:21HClsoo.. what should drawpixel do in that mode?
23:51:24HCljust draw fg color?
23:51:32*preglow gets an urge to code more on his ansi viewer
23:51:51amiconnLook at the table under 'concepts'
23:51:56preglowdrawpixel shouldn't have a bg, if you ask me
23:52:27HCldoh. i'm stupid.
23:52:29HClor i'm sleepy.
23:52:32HClone of the two.
23:54:11amiconnpreglow: Yes, all non-bitmap primitives consist of foreground pixels only. So the 4 modes actually become only 2 modes
23:55:41preglowmore tea for me
23:55:43amiconn...and the mode is global, as are the foreground and background values, but I think this less of a problem than having to pass all of these parameters to each primitive
23:55:45HClwhats the bresenham algorithm?
23:55:59HClor shall i just implement drawing lines with setpixels?
23:56:09HClwe can always optimize later
23:56:23preglowwhen drawing a line, you can usually just use setpixel
23:56:29preglowthe offsets have to be recalculated anyway
23:56:36preglowbresenham algo you can find tons of implementations of on the net
23:56:48 Quit rasher ("CGI:IRC 0.5.4 (2004/01/29)")
23:56:55amiconnThe free-directioned lines are drawn with single pixels anyway
23:57:23preglowyou can have a special case for hline and vline unless they are separate functions
23:57:27preglowthen you don't use putpixel
23:57:27amiconnThere already is a working implementation of that, using bresenham for calculating which pixels to set
23:57:55amiconnpreglow: Yes, I propose separate functions for hline and vline
23:58:08preglowyes, good idea
23:58:19 Join rasher [0] (
23:58:32amiconnI also do not propose to throw everything out and start from scratch. There's much code that is reusable
23:58:44HClyea, i'm noticing that.
23:58:50HClso far its been moving stuff and adding a switch for the drawmode
