but when i run my program i have this error 
A/D library not implemented 

i try to record using the mini recorder it didnt work !but the out audio
works fine 
what can i do ?

I think you find that most of the ADC is used for the touchscreen.  So,
that has to be disabled.

Here is a .zip of all the stuff I have found on ADCs on the mini2440.  It's
not much.

thanx for the replay
