Jim Lynch LCD code works on AT91SAM7X256 for olimex SAM7-EX?

Hello all,

I downloaded the software examples from sparkfun website for the SAM7-EX256 board using the AT91SAM7X256 chip and not the AT91SAM7S256 one.

This code is meant for AT91SAM7S256 and includes all related files. Is this compatible for and so runs on AT91SAM7X256 chip as well ?

If not, where could I find the sample demo LCD code for this board?

I searched the entire thread and could not find an answer.

Please help me.

Hi Aditya.

The code should work OK for your board.

The only major difference between the Atmel AT91SAM7S256 and the AT91SAM7X256 is a crypto feature that I suspect few users use to any advantage.

Cheers,

Jim Lynch

Hey Jim,

The code in zip file of your tutorial refers to the “ioat91sam7x256.h”

file which I cannot find in the code base. Where do I get this file from ?

Or should I include the “AT91SAM7S256.h” file instead ?

Regards,

Aditya

Hi

I can confirm that the SAM7X and SAM7S interface is compatible. The Olimex SAM7X-EX256 has the same Nokia LCD on it.

See also http://www.utasker.com/docs/uTasker/uTaskerLCD.PDF. This is the uTasker uGLCDLIB V1.1 user’s guide which includes this and various other displays - the displays and the processors can be fully simulated under windows, which makes development much more efficient :wink:
