| /** | ||
| * @defgroup boards_feather-m0 Adafruit Feather M0 | ||
| * @ingroup boards | ||
| * @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. | ||
| * | ||
| * ### Pinout | ||
| * | ||
| * <img src="https://cdn-learn.adafruit.com/assets/assets/000/030/921/original/adafruit_products_2772_pinout_v1_0.png" | ||
| * alt="Adafruit Feather M0 proto pinout" style="width:800px;"/> | ||
| * | ||
| * ### 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. | ||
