I have an Atmel AT91SAM7S-EK board with the 7S256 part mounted. I also have the tutorials from Atmel. The tutorials contain a file called "at91sam7s.h". The definitions inside this file are actually for the 7X256 and there are differences. For instance RXD0 is on PA5 of the 7S part but the definitiuon for it in the H file is as follows #define AT91C_PIO_PA0 ((unsigned int) 1 << 0) // Pin Controlled by PA0 #define AT91C_PA0_RXD0 ((unsigned int) AT91C_PIO_PA0) // USART 0 Receive This definition is correct for the 7X part but not the 7S. The blinky demo works on my board as it is supposed to and I assume that much of the 7X part is exactly as the 7S part but does there exist somewhere a header file that reflects the true definitions for the 7S part? Thanks!

The software-package http://www.atmel.com/dyn/resources/prod_documents/softpack-1.2-at91sam7s-ek-web.zip should include correct defintion-files. Extract one of the archives in the package and look into the directory at91lib/boards/at91sam7s-ek/at91sam7s*
