So, to start out, I live in tornado alley. I haven’t received my Artemis Redboard Nano yet, but have started programming. My Arduino Pro Micro just doesn’t have enough to do all that I want to do with the Si4707. So, I have started correcting compiling errors with the new board, and I am kinda running into a roadblock. So, I imagine the whole PROGMEM is unnecessary, so I fixed that. Next issue pertains to being able to disable the interrupts, and I have tried finding docs on the Artemis, but they seem to be greatly lacking. anyone know the equivalent register to the Atmel SREG register? Also have issues with the ADCSRA register. Probably will run into having to adjust the timer code as well. Lastly, is there a direct GPIO port on Artemis, like the Atmel PORTB? Thanks!
Unfortunately our code for the SI4707 was written at a time long before Artemis existed and relied heavily on AVR specific routines that don’t exist on the Artemis. You might use the code in the link below as a guide to porting over to Artemis but sadly we’re not really able to assist in porting the code.
