pemmican 1.0.3

Notify users of Raspberry Pi 5 power issues

Pemmican is a small utility which warns users of power supply issues on the Raspberry Pi 5 platform. It provides a command line utility, intended for use from the update-motd facility for non-graphical platforms, and two GLib-based applications for use on graphical platforms, which expect to talk to a DBus service implementing the freedesktop notifications specification:

• pemmican-cli – the command line utility

• pemmican-reset – the one-shot notification service which warns of brownout reset issues, and failure to negotiate a 5A feed

• pemmican-mon – the persistent notification service which warns of active undervolt or USB overcurrent events

Usage

End users should never need to run these directly; distro packaging should integrate these applications into the platform as appropriate (an MOTD plugin for the command line application, and systemd user services activated by graphical-session.target for the graphical applications).

What’s in a Name?

This project started life as PMICmon (for Power Management IC monitor), but I kept mis-pronouncing it as as pemmican!
