Compiling the blink_example program

Run the docker image

To proceed, you need to spawn a Docker container using the pipico_build_tool image that we built earlier and mount the blink_example directory from this repository as a volume.

sudo docker run -it -v FULL_PATH/pipico_build_setup/blink_example/:/app pipico_build_tool

💡 Please note that on certain operating systems, using a relative path with the -v switch may not work as intended. It is therefore highly recommended to use the full path to the blink_example folder instead.

Build our code using the docker container

⚠️ The below commands have to be executed in the docker container's bash prompt.

In the shell prompt of the docker container verify if the volume has been mounted successfully by executing:

 ls

should show some output like this:

CMakeLists.txt  main.c  pico_sdk_import.cmake readme.md

To build our program, we will first create a new directory called build in the container. Next, we will run CMake in this directory to generate the necessary makefile and configuration files. Finally, we will run the make command to build our program in the container.

mkdir build
cd build
cmake ..
make

Copying the program to Pi Pico board

After building the blink example, you can locate the resulting blink_example.uf2 file in the blink_example/build/ directory on your machine. This file can also be found inside the docker container at app/build/blink_example.uf2.

Once you have this file, connect your Pi Pico board to your computer by holding down the 'bootsel' button and releasing it once the board is connected. Then, all you need to do is copy the blink_example.uf2 file to your Pi Pico. Once done the board's LED should keep blinking.
