Setting up the Pico SDK
If you want to make the installation as simple as possible just follow the steps below (you can simply cut and paste these commands into your terminal):
Step 1. Create a new directory in your home directory to keep everything tidily in one place:
cd ~ mkdir pico cd pico
Step 2. Install the Pico SDK and examples:
git clone -b master https://github.com/raspberrypi/pico-sdk.git # Set the PICO_SDK_PATH environment variable to where you just cloned the repo. export PICO_SDK_PATH=/path/to/pico-sdk cd pico-sdk git submodule update --init cd .. git clone -b master https://github.com/raspberrypi/pico-examples.git
Step 3. Install the toolchain needed to build Pico projects.
sudo apt update sudo apt install cmake gcc-arm-none-eabi build-essential
macos (Using Homebrew)
# Install cmake brew install cmake # Install the arm eabi toolchain brew tap ArmMbed/homebrew-formulae brew install arm-none-eabi-gcc # The equivalent to build-essential on linux, you probably already have this. xcode-select --install
Step 4. Install the MicroPython port (optional):
git clone -b master https://github.com/micropython/micropython.git cd micropython git submodule update --init -- lib/pico-sdk lib/tinyusb make -C mpy-cross cd ports/rp2 make cd ../../../
Step 5. Install the Pimoroni Pico libraries:
git clone https://github.com/pimoroni/pimoroni-pico.git cd pimoroni-pico git submodule update --init mkdir build
And you're done. Everything is installed and ready to go.
A good place to start is to build our examples which will prove that everything is setup correctly. Our project is setup to mimic the approach that Raspberry Pi have taken so if you're familiar with building their examples this should be a familiar process.
cd build cmake .. make
make command has completed you'll see that a number of new files and directories have appeared in your
build directory. For the purpose of building our examples the one that matters is the
examples will be one directory per product, each of which contain at least one
.uf2 file that can be flashed directly onto your Pico.
