Welcome to the ATTiny Daemon Wiki!

The minimum you should read if you want to use the ATTiny Daemon are the following pages:

• Modifying the Geekworm UPS HAT - here you learn how to do the hardware modification of the Geekworm UPS Hat
• Programming the ATTiny - this text describes how you can compile the firmware on your computer
• Installation on the Raspberry Pi - installing a daemon on Linux is no problem, but this text describes it anyways.

The documentation is not yet finished, but I will add to it over time.
