No "cool" name here yet.
ATMEGA328p firmware for controlling an SPI-attached MAX7456 analog OSD overlay chip via simple text commands over UART connection.
I wrote this up because the existing OSD projects I found:
- Required implementations of special protocols like MAVLink to be used
- Were hacky decade-old abandonware I couldn't even get to build
So I made my own. It works for me, and I hope it may be useful to others too.
