From the project

Software and Documentation for the Radiohat2 Project

This is an early version of the folder full of files that need to be installed on a raspberry pi to allow experimentation with the RadioHat version 2.0 hardware.

When downloading and installing it, ensure that it is named "radiohat2" and that it is in your home directory, or some of the shell scripts it contains will not work properly. When downloaded as a .zip archive, it may result in a folder with the branch suffix "-main" that needs to be removed if you want to use the enclosed shell scripts.
