Compiling the dino_names_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 dino_names_example directory from this repository as a volume.

sudo docker run -it -v FULL_PATH/pipico_build_setup/dino_names_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 dino_names_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.cxx  pico_sdk_import.cmake readme.md

We will need the Eigen library for matrix multiplication in C++. So, we clone the library in the 'app' folder of the container. Also, we will use the pico-ssd1306 library from David Schramm to show text on OLED display , so let us fetch the source code of the two libraries from git

git clone https://gitlab.com/libeigen/eigen.git
git clone https://github.com/daschr/pico-ssd1306

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

Connecting the OLED Display

Ensure that the OLED display is connected to Pi Pico:

Display PIN Pi Pico Pin
VCC VCC
GND GND
SCL GP3
SDA GP2

Copying the program to Pi Pico board

After building the OLED example, you can locate the resulting dino_names_example.uf2 file in the dino_names_example/build/ directory on your machine. This file can also be found inside the docker container at app/build/dino_names_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 dino_names_example.uf2 file to your Pi Pico. You should start seeing randomly generated dinosaur names !
