[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

Hey,

You emailed me a while ago asking me the same thing - kinda, unfortunetly i
lost a bunch of emails a while ago when my system went down - sorry about
that.

Anyways - i am a windows programmer and i was going to play around with
C/C++ and making an interface for the iPod, but it looks like you beat me to
it.

I would be very interested in helping with the project though, maybe we are
in need of a sourceforge site? Heh.

Robert.

Re: [Ipodlinux-devel] Re: keypad problem

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

Hi Robert,

Intially this interface was just a test to my graphics library. And i 
have to say it is a pleasure to navigate with the wheel :).

Bernard purpose to host the the gui projet to the ipodlinux site and i 
think it is the best solution. It have to some check and find that 
Amstrad cpc was a 4 colors computer maybe we could grab some free artworks.

A also try to port a cpc emulator but the result is awfull because i 
have to convert from 320x200x4 to 160x100x4 :) Maybe old-computer
has a 160x128 video mode  to port the emulator and having to a low cost 
a lot of games. A rogue game should be possible too... i'll have to 
check one :)

Any ideas of what function could be good, how to launch program from the 
GUI with arguments (for exemple by parsing the --help options to reteive 
the arguments and allow selection on it or by parsing the man page 
associated .... ). So their is a lot of work to do.

I'm currently thinking how to do a Menu-SubMenu system (like apple ipod) 
   which to store and launch the differents functions.

So, i 'll release everything as soon as possible, but i have to say that 
  i program like a "pig" and i'm a litlle shy to allow other ppl to view 
it :)

Cheers,
Damien.
