ARM (cortex M) is boring. I'd like to see more accessible cortex R, otherwise i'll keep using dsPICs
There is little support for cortex I have found.
I have had to spend a lot of time finding out problems for myself.
And I still cant get PWM to work on atsame70n19.
If I put PCK0 on erase pin the processor keeps on crashing.
Even getting a basic running circuit is a mammoth task.
There is just very little support or info on it.
I got caught out with first 64 pin cortex as I couldnt get it to do USB despite it being advertised as doing USB and details in the datasheet. After a ticket to Microchip they just said "it doesnt work. You have to use 100 pin version for USB."
Unlike the PIC's the cortex throws a wobbler if you try to use programming pins for other functions.
The debugger locks up and you have to do an erase cycle on the cortex before you can program it again.
Its a fast processor but is just far too complicated.
