Hardware – TM1638 Hud software is now Assetto Corsa compatible.

A software Update for the Arduino & TM1638 board has been released to ensure compatibility with the current Beta release of the Assetto Corsa Simulator.
The software makes use of the API currently supplied with the Assetto Corsa Early Access build.

In this build, for now the API is limited to only a few outputs. For now the AC API only supports Gear changes, Speed indicator and RPM/Shift light arrays, used in Mode 0 on the Arduino & TM1638 board.
But this will probably change in the coming updates.
