Testing various hardware with the pico_w.
Clone and build.
git clone https://github.com/kubakos/pico-test.git
cd pico-test
mkdir build
cd build
cmake ..
make
Then copy the .UF2 to the Pico from the build directory of the corresponding hardware. To be able to see the recieved data from the pico you will need a serial communication program (e.g. bootterm, minicom).
