Installation

Building and loading applications

To build an application, use make inside of the application's directory.

make flash uploads the application to the board using JTAG.

Getting print data

The Micro:bit v2 prints information through a serial port at 38400 baud. You can connect with any serial terminal, but miniterm comes with pyserial and works pretty well for this.

$ pyserial-miniterm /dev/ttyACM0 38400
