SAMD21 board support #7

Closed newerbee closed 6 years ago

newerbee commented 7 years ago

Hi Zanshin,

Nice job with the library. But It looks like the library doesn't compile for SAMD21 based boards such as Arduino M0, or adafruit Feather M0. I am not an expert, but I happen to be using these boards, not sure what is wrong...

Let me look into that. I don't have any of those boards, but can try to set my IDE to one of them and see what the problem might be.

Sorry that this took so long to look into!

The reason was that the compiler settings were different and I was setting parameter defaults in the functions as well as in the prototype definitions. I've removed those from the function definitions and now the library compiles without a problem on SAMD21 boards.
