@brief Support for the Adafruit Feather M0.
|
|
|
|
|
|
|
|
|
|
### General information
|
|
|
|
|
|
|
|
|
|
Feather M0 boards are development boards shipped by
|
|
|
|
|
[Adafruit](https://learn.adafruit.com/adafruit-feather-m0-basic-proto/).
|
|
|
|
|
|
|
|
|
|
All the feather M0 boards are built based on the same Atmel SAMD21G18A
|
|
|
|
|
microcontroller. See @ref cpu_samd21.
|
|
|
|
|
|
|
|
|
|
Several types of Feather M0 boards exist:
|
|
|
|
|
* [Feather M0 WiFi](https://learn.adafruit.com/adafruit-feather-m0-wifi-atwinc1500/)
|
|
|
|
|
* [Feather M0 BLE](https://learn.adafruit.com/adafruit-feather-m0-bluefruit-le/overview)
|
|
|
|
|
* [Feather M0 Adalogger](https://learn.adafruit.com/adafruit-feather-m0-adalogger/)
|
|
|
|
|
* [Feather M0 LoRa](https://learn.adafruit.com/adafruit-feather-m0-radio-with-lora-radio-module)
|
|
|
|
|
|
|
|
|
|
The different modules used to differenciate the boards (ATWINC1500 WiFi,
|
|
|
|
|
Bluefruit LE, SD card, LoRa) are connected via SPI (SPI_DEV(0)) to the
|
|
|
|
|
SAMD21 mcu.

|
### Flash the board
|
|
|
|
|
|
|
|
|
|
1. Put the board in bootloader mode by double tapping the reset button.<br/>
|
|
|
|
|
When the board is in bootloader mode, the user led (red) oscillates smoothly.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
2. Use `BOARD=feather-m0` with the `make` command.<br/>
|
|
|
|
|
Example with `hello-world` application:
|
|
|
|
|
```
|
|
|
|
|
make BOARD=feather-m0 -C examples/hello-world flash
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
### Accessing STDIO via UART
|
|
|
|
|
|
|
|
|
|
To access the STDIO of RIOT, a FTDI to USB converted needs to be plugged to
|
|
|
|
|
the RX/TX pins on the board.
