First, install the latest version of the Raspberry Pi OS Bullseye onto an SD card. You can refer to the CircuitPython on Linux and Raspberry Pi guide for more help setting it up.
Once you have everything set up, you will need to open a terminal and install Blinka. Refer to the Installing CircuitPython Libraries on Raspberry Pi page to quickly get up and running.
Processing
On your Raspberry Pi, open the Chromium browser and navigate to the Download page of the Processing for Pi website.
At the bottom of the Download page, you will see a TGZ archive for Processing 3.5.3. Click on it to begin the download.
After downloading, move the .tgz file to your home directory. Open a new terminal window, and enter the following command:
tar xvfz processing-3.5.3-linux-armv6hf.tgz
This extracts the archive package that you downloaded and installs Processing onto your Raspberry Pi.
You can run Processing from the terminal with these commands:
cd ~/processing-3.5.3/ ./processing
