I am working with arduino IDE for about 4 years.
I consume a lot of arduino micro controllers, then i started to develop my own micro controllers.
For about a week i am trying to port the SAMD21J18A to the arduino IDE and still not having any success with it.
I am using the latest version on the arduino IDE.
I need help. I have some of SAMD21J18A processors and also have the Atmel SAMD21 Xplained pro.
i tried some solutions but they aren't working...
I tried:
Arduino IDE Board Manager module for Atmel SAM D21/W25/R21 Xplained Pros from
ZeroPi from
Never had problems with Arduino zero (ATSAMD21G18 x 48 pins), but need to port the SAMD21J18 (64 pins) because it have more PIO ports available.
I really appreciate some help here, if anyone had success with it, please help me.
Thanks in advance.
