What am i doing wrong?
Hi Gert, you can find different books about Cortex-M, I personally found this very useful: "The Definitive Guide to ARM Cortex-M3 and Cortex-M4 Processors" by jyiu.
I would also suggest to look at the specific documentation from Atmel about SAM E70: SAM E MCUs
Extra links can be also found here: Getting started with ARM Microcontroller Resources
Hope this helps.
Best Regards,Stefano
