Support for the Adafruit Feather M0.
Feather M0 boards are development boards shipped by Adafruit.
All the feather M0 boards are built based on the same Atmel SAMD21G18A microcontroller. See Atmel SAMD10/SAMD20/SAMD21/SAMR21.
Several types of Feather M0 boards exist:
The different modules used to differentiate the boards (ATWINC1500 WiFi, Bluefruit LE, SD card, LoRa) are connected via SPI (SPI_DEV(0)) to the SAMD21 mcu.
AIN7 can be used to measure the voltage of a connected Lipoly battery. It is mapped to ADC_LINE(6) in RIOT.

To enable the WiFi interface of the Feather M0 WiFi variant of the board automatically for networking applications, use
feather-m0-wifi as board and define the required WiFi parameters, for example:
For detailed information about the parameters, see section ATWINC15x0 WiFi module driver.
To enable the LoRa module available on the Feather M0 LoRa variant of the board automatically for LoRa applications, use
feather-m0-lora as board:
For detailed information about the parameters, see section Semtech SX1272 and SX1276 radios driver.
STDIO of RIOT is directly available over the USB port.
TERM_DELAY environment variable can be used to add a delay (in second) before opening the serial terminal. The default value is 2s which should be enough in most of the situation.
