@brief Support for the BBC micro:bit v2
|
|
|
|
## Overview
|
|
|
|
The [micro:bit v2](https://www.microbit.co.uk/) was designed by the BBC and
|
|
released in 2020.
|
|
|
|
The board is based on the Nordic nRF52833 SoC, featuring 128KiB of RAM, 512KiB
|
|
of ROM, and a 2.4GHz radio, that supports Bluetooth Low Energy (BLE), 802.15.4
|
|
as well as a Nordic proprietary radio mode.
|
|
|
|
Additionally the boards features 2 buttons, a 5x5 LED matrix, a speaker, a
|
|
microphone, an accelerometer and a magnetometer.

|
## Flashing and Debugging
|
|
|
|
The board can be flashed using OpenOCD and PyOCD. Debugger is also available
|
|
with both programmers.
|
|
|
|
```
|
|
BOARD=microbit make flash
|
|
```
|
|
|
|
## STDIO
|
|
|
|
The programmer chip provides access to STDIO via USB. On Linux, stdio is
|
|
usually available on /dev/ttyACM0. Use the `term` target to access stdio:
|
|
|
|
```
|
|
BOARD=microbit make term
|
|
```
|
|
|
|
## Display
|
|
|
|
The 5x5 LED matrix display can be driven using the @ref boards_common_microbit.
|
|
|
|
## Button setup
|
|
|
|
The Microbit logo and the rings are configured in resistive mode, and expressed
|
|
as buttons by default when SAUL is enabled (through @ref saul_gpio_params_t).
|
|
Note that to press them, you have to touch the GND pin at the same time, and
|
|
may need to press hard if you have dry fingers. See [the micro:bit documentation on touch]
|
|
for more information. Capacitive mode is currently not supported.
