Compile Mesa from source (note: doing this makes it difficult to get back to a clean package install):

Allow sources to be installed via apt:
1. Bookworm and earlier: Uncomment the deb-src line inside /etc/apt/sources.list.d/raspi.list and save it
2. Trixie and later: Edit /etc/apt/sources.list.d/raspi.sources and add set Types to Types: deb deb-src and save it
Install build dependencies:
1. sudo apt update && sudo apt build-dep mesa -y
2. sudo apt install python3-pycparser
Install later version of meson:
sudo apt remove meson -y

PicoBricks Microcontroller Demos

These .pb (PicoBricks) IDE files are meant to be used with a PicoBricks board. I demonstrate how they all work (and how I built them) in this YouTube video:

How to use these files

These files are meant to be opened in the PicoBricks BricksIDE, available on http://ide.picobricks.com
