02:03:43[xLE]Aarondo you guys deal with any of the newer archos stuff? (av300, etc)
02:04:33lImbusI am an absolute noob, but as far as I know, there have been researches ongoing for gemini
02:05:11lImbusfurthermore, a "NEO" from a complete other manufacturer is supported, or beeing supported
02:07:16[xLE]Aaronreally all I want is a device that can run wince and use winamp as its shell and display milkdrop on the lcd. is that too much to ask? :)
02:07:34[xLE]Aaronalso wireless access.
02:08:00lImbusehhh. is there a winamp for winCE ?
02:08:02[xLE]Aaronthe new archos stuff seems like the most likely candidate for hacking, but I've just started researching things so I really have no idea.
02:09:03[xLE]AaronI think there's a build for pocketpc.
02:09:34lImbusimho an existing rocbox on an archos jukebox recorder is more than winamp on CE. it even has display-plugins ;-)
02:10:56[xLE]AaronI've only just now discovered rockbox, so you're probably right. might be easier to port milkdrop to rockbox.
02:13:15lImbuswell, if you really need that as addition to your drugs ;-)
02:14:14 Quit mecraw__ ("Trillian (http://www.ceruleanstudios.com)")
02:15:31lImbusbtw: you'd still need a winCE-edition of milkdrop. afaik winCE has a slighty modified Direct3D engine
02:19:28[xLE]Aaronfrom the nodo list: 13. Graphic frequency (spectrum) analyzer!
02:19:28[xLE]AaronWe can't access the audio waveform from the MP3 decoder so we can't analyze it. Even if we had access to it, the CPU would probably be too slow to perform the analysis anyway.
02:21:15lImbusjup. it was a little trick when I said it even had display-plugins. there are two plugins (oscilloscope and vu-meter) that do what you'd expect redaing the name.
02:21:22lImbus*reading the name.
02:22:57 Quit solaris (Read error: 54 (Connection reset by peer))
02:30:37[xLE]Aaronsounds like the av500 might be using QTopia (linux) which might make it hacktastic.
02:30:56[xLE]AaronI think that might be what the sharp zarus was using.
02:31:12lImbuswhere does it sound like that ?
02:32:51[xLE]Aaronoops.. just closed the window. hold on

03:41:27diddystar5im not sure, it may fix that
03:41:33diddystar5do you have a compile log?

03:42:49top_blokewell i guess i'll try mid's way
03:42:55diddystar5if you have your archos, just plug it in and store it on there, when cygwin setup runs, tell it to download, and tell it on your archos or wherever
03:43:14top_blokeyeah
03:43:17diddystar5just make sure you have those setup.log and setup.log.full files wherever you save everything
03:43:25top_blokewhy
03:45:28diddystar5it will screw up if you dont when you go to install your downloaded files

10:15:39scott666ahh, right
10:16:52amiconnThere was quite some space waste in the lcd code. The lcd_write_data() function, although defined for the player, was never used on it.
10:16:55Ralle[DK]i just addet 4x2300 batteries to my archos
10:17:16scott666hood for you
10:17:25midkscott calm down now
10:17:26amiconnVice versa, the data-writing part of lcd_write() wasn't used on the recorder.
10:17:31scott666*good
10:17:38BC|codingwell spotted ami
10:18:34amiconnSo I unified that to use lcd_write_data() for data on player & recorder, and turned lcd_write() into lcd_write_command().
10:19:54BC|codingthis code is annoying me now - ami....

10:24:44Ralle[DK]why cant i download the recorder simulator for windows?
10:24:47amiconnWhat do you mean with "complete redraw"? Are you talking about issuing lcd_update() every time, or is the whole screen content changed?
10:24:56BClcd_update
10:25:44BCthe screen is redrawn - but not much will have changed
10:26:34amiconnThen it is np, since you don't need (and in fact must not call!) lcd_update() for grayscale. The grayscale display is automagically updated with every drawing operation due to the way grayscale works.
10:27:04BC"must not call"?
10:27:20BCwhat if only half the screen is greyscale - how do i update the other haldf?
10:27:20midkawho wants to see mids perfect picc
10:28:21amiconnYes, you must not call lcd_update() while the grayscale overlay is running, because the lcd is driven with an interrupt routine then.

10:40:58 Part Ralle[DK]
10:41:21amiconnAlthoguh it should be relatively straighforward to use, there may be some pitfalls.
10:41:27amiconn*Although
10:42:31BCyes, I'm just trying to think ahead without distracting my brain from my own source code
10:42:32***Alert Mode OFF
10:42:47amiconnFor instance, the lcd_xxxrect() functions expect coordinates in (x, y, width, height) format, while gray_xxxrect() expects them as (x1, y1, x2, y2).

10:49:04amiconnBC: Imo double buffering cannot be implemeted for several reasons
10:49:59amiconn(1) The plugin buffer is very tight (at least as long as you don't use the mp3 buffer) to even fit one set of bitplanes for grayscale.
10:50:32BCthe plugin could offer up it's space for as many Z planes as it wanted
10:51:54amiconn(2) The frames generated from the bitplanes are inter-dependent (that's how grayscale works!), so flipping to another set would very likely look bad.
10:53:10BCokay then
10:53:24BCi shall rethink my thunks
10:54:18BCI feel the desire for a grey_update
10:54:48amiconnTo (1). If you want 33 shades, there are 32 bitplane which take up 28,852 bytes for fullscreen, so there is no room for a second set.
10:54:58BCwrite to a BYTE based (not bit based) buffer - then it can OR and XOR them together on ussue of an update()
10:55:27BC16 greyscales will be plenty more than we can use imho
10:55:46BCother than image display
10:56:01BCwhere does the 28K come from?
10:57:03amiconnByte-based buffer: this would have to re-generate all bitmaps from that buffer when you call the hypothetic gray_update() - this would take ~ 0.8 seconds!
10:57:56BCbut if you hold the current display as a reference you onnly need update the bits that change
10:58:36amiconn28K: LCD_WIDTH * (LCD_HEIGHT/8) * number_of_bitplanes + some more bytes for precalculated bit patterns etc.
10:58:43BCsorry
10:58:56BCwhat memory space does it occupy
10:59:23amiconnbc: whatever memory you give it, read the comment for gray_get_buffer()
10:59:29 Quit scott666 ("i'll be back...eventually...")
10:59:39BCat 896bytes per Z plane I could afford a few :)
10:59:54BC...and animation is mine :)
11:00
11:00:20amiconnNo, you need n * 896 bytes with n = (number of grayscales - 1)
11:00:42BCno you only need that for what is actually being displayed
11:01:17BCan image TO BE displayed would be 64*112 /8 bytes -each holding a greyscale value
11:02:08BCwhen you grey_update() you OR all the planes together - then & it with the old byte-buffer and plot the changes?
11:02:10amiconnThis would take 64*112 _bytes_ - you cannot fit a grey value into a _bit_, can you?
11:02:26BCoh shit!
11:03:07BCat 16 grey scales you only need 3.5K
11:03:52amiconnBtw, I already tried your idea to only update changed bits - this speeds it up by a whopping 14% (sic!) if there are no changed bits, but slows down by 6 % when all bits are changed.
11:04:13amiconnIf use use 3.5 K for 16 grayscalkes then your buffer is not byte based.
11:04:15BCi would pay that price
11:04:26BCno, i stepped down to nybbles
11:05:00BCoh hang on - 14% of 0.8 seconds?
11:05:42amiconnyes, down to ~0.7 seconds then.
11:05:46BCWhen I've finished this code - I'll see what I can actually do
11:05:52amiconnThe problem is that your gray_update() idea still has to set every pixel separately.
11:06:05BCwhat if *I* plot only changed pixels?
11:07:04amiconnOf course you could do that, but I expect slowdown if the display has changed a lot.
11:07:28BCbut change will be kept to the absolute minimum this way
11:08:23BCand of course some of the work will be being done in the plugin interrupt
11:08:36amiconnI still don't get why you would do that in the first place. If you simply draw with the gray_xxx() functions, you change exactly the same amount of pixels.
11:09:01BChow else do you overlay sprites?
11:10:39amiconnHmm, I did not think of using sprites until now. Perhaps I could implement a sprite function.
11:11:05BCI have quite a collectin of them
11:11:37BCrotations
11:11:41BCinvertions
11:11:52amiconnThis would work similar to the bitmap function, with the addition that you would have to give a memory buffer where the original display content would be stored.
11:12:10BCyes
11:12:17BCat 3.5K per layer
11:12:30BC+3.5K for the "current" image
11:13:09amiconnI thought of using a memory buffer just as large as to hold the part of the display that is changed by the sprite.
11:13:45BCyes, you could implement sprites that way too - that would be even better
11:14:26BC0=white, 15=black, 1=transparent
11:14:58BCthen add sprite collision algorithms would be simple and faster this way too
11:15:03amiconnThere is a simple way if you want something like a cursor: Just invert a rectangle. If you invert again, it's gone.
11:15:14BClol
11:15:19BCindeed - othelo
11:15:49BCwhat if you want to know if the two blokes have touched each other?
11:17:00amiconnThat is not part of my framework. The framework just tries to resemble the lcd_xxx() drawing functions for grayscale.
11:17:11BClol
11:17:14BCfair enough
11:17:36BCjust seemed like it would be "up your street"
11:18:02amiconnBut in fact, I already thought of having something like a sprite function (though without collision detection ;-)) because I may need that for minesweeper.
11:18:34BCnick the othelo code
11:18:46amiconn(If I don't use my simple "invert cursor" idea)
11:21:18amiconnFrom another point of view, you can see my idea to implement sprites by storing away overlaid data in a dynamic buffer as some sort of "windows"
11:21:44amiconnThis would in fact also be useful for the rockbox core, at least in b & w
11:23:11BCagreed
11:23:19BCbut pointless to implement it in b&w now
11:24:32 Quit Rallie ()
11:25:16amiconnConcerning the speed of grayscale: It depends (roughly) linear on the number of grayscales, so 16 grayscales are (almost) twice as fast as the maximum of 33.
11:26:06BChow many greys do you think a game would need?
11:26:28BCthe thing is, if you go below 16, the math becomes horrible
11:26:52amiconn8 to 16 (imo).
11:27:13amiconnWhat's the problem with the math?
11:27:45BCgetting a nibble must be more efficient than finding a triplet?
11:28:52amiconnIf you really want double buffering of course you have to do that.
11:29:23amiconnBut there is nothing that prevents you from using 4 bits even if there are only 8 grayscales.
11:29:44BCfair
11:30:07amiconn(only that it is a slight waste of space.)
11:30:22BCmemory -vs- speed ...the age old debate
11:32:04amiconnUsing my framework you are not restricted to use a number of grayscales that is a power of 2, you can use any number from 2 to 33.
11:32:31BCi know
11:33:17BCI think you are right - these ideas are perhaps misplaced in the grey_ stuff
11:35:03amiconnAs long as it is not placed in the grey... Nevertheless this is a good idea - to create another framework that does double buffering and sprite stuff for use in games.
11:35:40BClove to see some decent platformers - and they're not that hard to write really
11:37:01amiconnYes, platform games could be possible.
11:37:38BCwith realtime mixed audio
11:37:42BC....in mono :(
11:37:59amiconnBut imo it is not possible to do realtime 3D. There is simply not enough power even if you use double buffering, since with 3D almost every pixel changes evrytime.
11:38:46BCremember the old DOOM window size option - lol
11:39:11BCsaw doom on a spectrum once!
11:40:31amiconnIf you want to play Doom in an 24 x 40 pixel "window" with 16 grayscales (quick estimation), then it may work.
11:40:38BCLOL
11:40:45BCyou might be about right ;)
11:41:19amiconnThe above figures should deliver just above 30 fps...
11:41:44BCI'd be happy with 22 (67/3) I think
11:42:21BCplus you have a black ceiling - so that's a bunch of stationary dots
11:45:00amiconnIf you ever tried video, you know that the lcd is not the fastest, so you get a lot of motion blur. It is by far worse that state-of-the-art TFT monitors, which are even considered unsuited by hardcore gamers...
11:45:46BCbut as you know - it's not about getting gamers to buy obselete kit - its about proving it can be done
11:47:07amiconnMy point is that perhaps 17 fps or even 14 fps would be sufficient.

16:31:30brainlockthere are no differences between the JBR20 and JBR6 for hard drive upgrades right?
16:31:53BC|busyphysically or electronically?
16:32:46brainlockboth... my friends jbr20 (w/ firmware 1.28) had his hard drive die... so i'm going to upgrade my jbr20 (firm 1.26) and then give him my old 20gig drive
16:33:11brainlockand i'm looking at the tut's for jbr6's cuz that's all i can find..
16:33:20brainlockjust wanted to make sure i'd be okay...
16:33:28BC|busyphsycially I guess the scews will all be in different places etc - electronically - just put a new hdd in it :)
16:33:44brainlockcool... that's what i wanted... thanks BC|busy
16:33:52BC|busywelcome ;)
16:34:23brainlocki've found the 2 tut's on rockbox's website... those should get me through it with no problems right? i'm reading them now.
16:36:21BC|busyother than the screws (etc) it is as easy as swapping a PC hdd - sadly I've never done it myself and although I have read everything at some point - I would not like to comment on how complete they are - I suppose logic dictates that if there were any errors someone would have shouted a long time ago :)
16:36:38BC|busythey=tut's
16:37:06brainlocki just finished a complete xbox mod.. with chip and drive... and i guess i'm just expecting things to be alot more complicated ...
16:37:16brainlocklooking at it.. i can't believe how simple it is :)
16:37:26brainlocknow i just have to find a driive i know will fit
