This is an attempt to build a minimal, custom PCB featuring an STM32L4 MCU, using (ideally only) open source tools. It will hopefully serve as a stepping stone to build more complex embedded systems.
Because learning is fun.
To set up this project, you can start by cloning it:
$ git clone https://github.com/kokkonisd/custom-pcb
You then need to pull libopencm3. You can do this by running make in hello_opencm3/, or do it manually:
$ git submodule init
$ git submodule update
$ cd hello_opencm3/libopencm3/ && make
You only need to do this once.
