Basic boilerplate for the Pico /-W boards.
Downloads Pico SDK from github.com on cmake generation.
Assuming Ubuntu based os (Ubuntu, PopOS eg.)
Ninja is optional and standard make can be used as well.
sudo apt install gcc-arm-none-eabi libnewlib-arm-none-eabi libstdc++-arm-none-eabi-newlib ninja-build
Configuration is done in CMakeLists.txt.
| Option | Default | Description |
|---|---|---|
| PROJECT_NAME | "pico" | Project name |
| PROJECT_VERSION | "0.0.1" | Project version. Also available as generated header as "version.hpp" |
| PICO_BOARD | "pico_w" | Board to use. Available options are "pico" or "pico_w". 1) |
| USE_STDIO_USB | 1 | Use USB as stdio output |
| USE_STDIO_UART | 0 | Use GPIO as stdio output |
| OUTPUT_NAME | "output" | Default filename for all output files (hex/elf/uf2) |
- The
PICO_BOARDdefinition is forwarded as a c++ definition by default but instead of having to read the value you can simply check ifWIFIis set (if undef the board is the original Pico).
Download and create build directory
export PICO_PROJECT="boilerplate"
git clone https://github.com/fredrikasberg/pico_boilerplate.git ${PICO_PROJECT}
cd ${PICO_PROJECT}
mkdir -p build
cd build
and compile using Ninja
cmake -GNinja ..
ninja
or using Make
cmake ..
make
You can now copy the default output.uf2 binary to the pico.
The on-board led should be flashing and the usb serialport should be outputting data.
Easiest way to view output is with minicom.
minicom -b 115200 -o -D /dev/ttyACM0
# To quit
# CTRL + SHIFT + A then release and press Z
# q ENTER
or with screen
screen /dev/ttyACM0 115200
# To quit
# CTRL+a
# :quit ENTER
Note Make sure you are in the dialout group (sudo usermod -a -G dialout $USER).
