I’m just an electronic hobbyist (and physic teacher).
I’d like to make a sort of chronometer for my Go-Kart.
It’s working fine now
(using WinAVR as C compiler
for a microcontroller (uC) ATMEL AVR ATmega8535)
but I use a character LCD display.

I would like to use a graphical LCD now.
But I also would like to have some widgets (like in GTK+)
Unfortunately I don’t know if it is possible to do it without a minimal
Linux on the uC (I’m also fond of open source softwares and Linux… of
I guess that having a Linux kernel is too much for a little 8 bits uC
like ATMEL AVR so maybe FreeRTOS can be a solution for me.

About the GUI,
There is no mouse or touchscreen
so the GUI should be like the GUI of a phone or any embedded device
that’s to say that there is only
- up/down/left/right buttons
- ok button
- cancel button

I hope you could help me for this.
