Using with Arduino IDE

Since the Feather/Metro/Gemma/Trinket M0 use an ATSAMD21 chip running at 48 MHz, you

can pretty easily get it working with the Arduino IDE. Most libraries (including the popular

ones like NeoPixels and display) will work with the M0, especially devices & sensors that use

i2c or SPI.

Now that you have added the appropriate URLs to the Arduino IDE preferences in the

previous page, you can open the Boards Manager by navigating to the Tools->Board menu.

Once the Board Manager opens, click on the category drop down menu on the top left hand

side of the window and select Contributed. You will then be able to select and install the

boards supplied by the URLs added to the prefrences.

Install SAMD Support

First up, install the Arduino SAMD Boards version 1.6.15 or later

You can type Arduino SAMD in the top search bar, then when you see the entry, click Install
