I installed Arduino SAMD Boards through the board manager, but I do not see a SAMD folder under Arduino/hardware/arduino. I only see the avr folder. I was expecting to see the variants and other type of files under in that folder. Do I have to compile from source?
Which SAMD based board do you have ?
Once the boards package is installed there is not normally an reason to do much more other than plug in the board.
Exceptions being a home brew SAMD or an off brand SAMD.
Look in the .arduino15 folder.
gdsports - That is what I was looking for. Thanks
