This microcontroller can be used to add a compass to a seat hud.
It can be set to use both the POV elevation and heading, or just heading, to draw the compass.
The compass can either use a ship compass, to show headings, or standalone to just show where you are looking relative to the seat position.
Use the toggles to set the mode you want.
There's also a pass through to chain other hud element, from other microcontrollers, to create a complete HUD.
