Misc and Mod
by Till Gerken 01 Aug '01

Hi all, just subscribed to this list. Hope that it will be active again. :) I sent the libmikmod port and instructions (very very simple, beware) to Sven, eventually he'll put it up along with the font routines on his new page. Till

Anybody in here? - libempeggraphics
by Sven Mueller 31 Jul '01

31 Jul '01

Hi. I just wanted to see how many empeg developers are subscribed currently. I would like to discuss a few ideas, and I don't think the UEBBS is the right place to do so. OK, what I am thinking about is a set of libraries to help develop programs for the empeg. My main objectives are: Graphics, Sound and serial/USB/network communication. For a start, I will try and concentrate on the graphics part. So here is what I think the library should provide, and I would really appreciate some feedback on this. The preliminary specs I state below are for a C++ library (with overloaded functions), but I intend to provide a pure C version as well, probably using a C++ wrapper around a C lib. The first goal is to provide a few simple commands to access the display. I think the following functionality should do for most (if not all) applications on the empeg (except for applications that want/need virtual 3D): Basic display device handling: - open display / initialise - close display - turn on/off display - clear the display queue Basic page handling - create virtual page - free virtual page - add virtual page to the display queue - display virtual page now - dump virtual page to file (or memory area) - load file (or memory area) to virtual page Basic drawing commands - clear virtual page - select current page for drawing - plot(page,color,x,y) plot(color,x,y) (plots to current page) plot(x,y) (plots in current colour) - line(page,color,x1,y1,x2,y2) line(color,x1,y1,x2,y2) line(x1,y1,x2,y2) (well, you get the picture) draws a line from (x1,y1) to (x2,y2) - circle([[...],fillcolor],x,y,r) draw a (filled) circle - triangle([[...],fillcolor],x1,y1,x2,y2,x3,y3) draw a (filled) triangle with the given edges - stamp(x,y,*bitmap) output a bitmap with a lower (or maybe upper) left corner of (x,y) - grab(x1,y1,x2,y2,*bitmap) grab a fraction of the display and store it in bitmap Text functions - setfont(*font) (set the font to use) - loadfont(FILE) (load a font from a file) - text([[...],*font]x,y,*text) print *text using *font with a lower (upper) left corner of (x,y), supporting line breaks Scrolling support - create big virtual page (xsize,ysize) (all above commands apply to a big page as well) - display big virtual page (page,xoffset,yoffset) - merge big page to page (normal_page,x,y,xsize,ysize,big_page,xoffset,yoffset) inserts an xsize*ysize sized fragment of big_page, starting at (xoffset,yoffset) into normal_page at (x,y) I intend to add higher level later, but I think this should be a good starting point. What do you guys think? Did I miss something, should I leave out something (why)? I will do a better spec later this week, but would like to get some feedback first. Don't hold back, I can stand (constructive) criticism. cu, sven -- Sven Mueller Tel: +49-231-401550 Giessereistr. 11a Mobil: +49-172-2323802 D-44289 Dortmund email: sven(a)incase.de

Is this thing on?

...and, more to the point, can I get mailman to allow posting from a different address than the one I'm subscribed on? Cheers, Roger.

Guaranteed boot
by Marius Hauki 10 Aug '00

10 Aug '00

How can we be shure that the file system will not get corrupted so that Linux wont boot ? Lets say the file allocation table gets screwed up e.g. I think I saw something about swapping back and forth between several partitions in the start up msgs from the kernel and one of the partitions were always write protected. Any advice would be appreciated. Marius Hauki

Beta10a needs binutils 2.9.5
by Kim Salo 20 Apr '00

20 Apr '00

Does anyone happen to have a compiled version of arm binutils 2.9.5? The new Beta10a kernel requires that and the pre-built toolchain has an older version of it. I know where to get the sources for that, but it would be easier if someone would've done the compilation already :) (Maybe an update to the current pre-built toolchain, what you think, Rob? :) PS. I want my IrDA support back! :) - Kim

Can anyone get sound with Beta10a?
by Kim Salo 31 Mar '00

31 Mar '00

Can anyone get sound outside the player with Beta10a? I've tried the pcmplay, but I'm not able to hear anything. I've checked that I have PCM source selected and that my output is unmuted. I know this used to work before... Can anyone reproduce this problem with Beta10a? Thanks, Kim

Quick question.

When I hit reply to one of the posts in my mailbox, will I then reply to eg. Kim, or Rob or will it go directly to the list. Do I need to create a new mail to the list if I want to answer on something for everyone to read?? Sorry for these novice questions but.... TommyE
