Setup

1. Install mbed-cli
2. Install the GNU Arm Embedded Toolchain
3. If the toolchain is installed to the default path, configure GCC_ARM_PATH as below:

mbed config -G GCC_ARM_PATH "C:\Program Files (x86)\GNU Tools ARM Embedded\9 2019-q4-major/bin"

4. Clone this repo
5. To load the dependencies, run:

mbed config root .
mbed deploy

6. To compile the program, make sure the board is plugged in to the computer and run:

mbed compile -m auto -t GCC_ARM

This should give you a .bin file in the BUILD folder which can be flashed to the board by dragging the file to the mounted volume.

7. Download Putty
8. Connect through serial port COM3
