Pi pico rp2040 minimal pico-sdk project template

Pi Pico Minimal Build

This is a minimal build template for a Raspberry Pi Pico project using the Pico SDK and CMake.

Prerequisites

• CMake 3.13 or higher
• Pico SDK

Setup

1. Update the PICO_SDK_PATH in the CMakeLists.txt file with your own Pico SDK path.
2. Set the PICO_BOARD in the CMakeLists.txt file to your specific Pico board model.
3. Set the PROJECT_NAME in the CMakeLists.txt file with your project name.

Build

To build the project, navigate to the project directory and run the following commands:

mkdir build
cd build
cmake ..
make

This will generate the necessary executable and other output files for your project.

Flashing the Build to Pi Pico

After building the project, you can flash the generated binary to your Pi Pico using picotool. Here are the steps:

1. Install picotool by following the instructions on the picotool GitHub page.
2. Connect your Pi Pico to your computer. Hold the BOOTSEL button while connecting to enable the UF2 bootloader mode.
3. Use the following command to upload the binary to your Pi Pico:

cd build
picotool load <your_project_name>.uf2

Usage

The main entry point of the project is src/main.c. Add your source files to the add_executable function in the CMakeLists.txt file and link any additional Pico SDK libraries to the target_link_libraries function.

You can enable UART output or USB output by uncommenting the respective lines in the CMakeLists.txt file.
