SAMD21J18A

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.

Can you be more specific?

Arduino IDE Board Manager module for Atmel SAM D21/W25/R21 Xplained Pros from
GitHub - AtmelUniversityFrance/atmel-samd21-xpro-boardmanagermodule: Arduino IDE Board Manager module for Atmel SAMD21 Xplained Pro and derivatives

It certainly looks like that should be what you want. Are you following the instructions in their wiki?

For me the solution from

works!
