whitequarkthat's way more complex, isn't it?00:00
wpwraki could probably make one at home :)00:00
whitequarkthat's you00:00
wpwrakbut yes, an stm32f2-based system would be easier to make at home00:00
whitequarkyou can do BGA for breakfast :)00:00
wpwraknaw, i don't do BGA :) that's xiangfu's speciality00:00
whitequarkI mean, I'm pretty sure I do not want to debug glitches in a parallel bus if I can avoid it00:01
whitequarkand laying out SDRAM when you only know how to work with dumb SoCs is just asking for trouble00:01
wpwrakoh, you try not to have that sort of problems :) if you screw up, you're screwed ...00:01
wpwrakbut this sort of things should still be doable by following design rules. it's not the sort of witchcraft you have with RF.00:02
whitequarknow that I think about it. so do you know decent embedded GUIs for linux?00:03
whitequarkand I mean not GTK, QT or even E17n00:03
whitequarker, englightenment? forget how it was contracted00:03
whitequarkhm, you can probably build motif.00:03
wpwraki use gtk and sdl. gtk for "GUI-y stuff", SDL (with SDL_gfx) if i basically just need a canvas00:04
whitequarkwell, SDL abstracts the underlying platform down to a framebuffer :)00:04
wpwrakthere's also some toolkit that sits on top of SDL. looks pretty fancy. lemme see if i can find it ...00:04
whitequarkso you won't need it on stm32 'cause it already has just a framebuffer00:04
wpwrakhaven't used that yet, though00:05
whitequarkI imagine that would be easily ported to the stm chip.00:05
whitequarkit's even 32-bit, to make things easier.00:05
wpwrakSDL_gfx also provides some useful primitives. but yes, you could implement them on your own in a week or so00:06
wpwrak"e" also has a bunch of infrastructure libraries00:06
whitequarkdid they intentionally make it ungoogleable?00:07
wpwrakmotif was considered an obese monster. so by today's standards, it's probably extremely light-weight ;-)00:07
whitequarkthat's what I thought00:07
whitequarkbut it needs X00:07
whitequarkand, well00:07
whitequarknothing needs more X.00:07
wpwrake = the enlightenment clan of libraries00:08
whitequarkah, right00:08
wpwraksee the stack here: http://www.enlightenment.org/00:08
whitequarkyeah. I imagine it's not easily ported, ie, you'd only want to use that over Linux00:09
whitequarkthey do claim that their library works on some quite underpowered devices though00:09
wpwrakyeah, 200 MHz ... but 16, maybe 8 MB of RAM :)00:40
Action: whitequark nods00:49
