Hi,

 

I have running software and API's for wireless transceiver ATmega128RFA1. I want to switch from Atmega to SAM R21 chipset (ATSAMR21E18A-MF).

 

Can I still reuse the same software and APIs? what and all changes I should expect while migrating from Atmega to SAM R21 chipset?

 

Thanks for Answers. 

Best,

Aniket

Hi - no, the SAMR21 is an entirely different chip. You would have to "port" the code over to use. The good news is you can reuse some of the functions, but when it comes to the HAL, you will have to write it to match your target hardware.
