[Ipodlinux-devel] Re: keypad problem

[damien m. <Dam...@li...>]

Hi,

thank for the the advice about keypad (opening "/dev/console") now it 
work really well, i'm so proud of using the wheel in my code :) .


I'm currently doing a little interface (gui) for my g3 ipod, currently i 
can only navigate in the directories, changing contrast with a slider, 
and  starting executables. To do this i have a little graphics library 
(drawLines, putPixel, putSprite, changeContrast).
Do some of you  have similar project ? Maybe we could merge, or define a 
common interface where we could plug our functions ?

Is their any people interested ?

Cheers,
Damien
