P4r4d0x42 / argon-one-case-ubuntu-20.04

port of the argon one case power button and fan script for Ubuntu 20.04 on rpi 4

Script for the Agon 1 case adapted for Ubuntu 20.04

Description

The argon one case is a solid case for the Raspberry Pi 4 (see https://www.argon40.com/argon-one-raspberry-pi-4-case.html)

This script has been adapted from https://download.argon40.com/argon1.sh which is designed to work with Raspbian (Raspberry OS), to work with Ubuntu 20.04.

There are mainly three changes compared to the original:

1. need to use python3 everywhere since python2 support for GPIO has been nuked in Ubuntu 20.04.
2. reading the temperature cannot be done using vcgencmd, but we can use the sysfs instead
3. the list of packages on which the script depends has been adapted to Ubuntu 20.04

Install

cd /tmp/
wget https://raw.githubusercontent.com/meuter/argon-one-case-ubuntu-20.04/master/argon1.sh
/* inspect script if you're paranoid */
chmod a+x argon1.sh
sudo ./argon1.sh

Usage

The script will generate a bunch of scripts and config files. The main commands are

• argonone-config to config the fan behaviour
• argonone-uninstall to remove all the scripts and services (conf file remains though)

I also added a custom command:

• argonone-tempmon which monitors the temerature using the linux sysfs.

Warning

This has been developped in an afternoon, and has been only tested on my Raspberry Pi 4. No issues so far, but big disclaimer nontheless: use at your own risk.
