Yes i can help you ^^ Sry somehow i dont get notifications from this forum anymore, thats why ive not answered sooner 😅
You will need an Arduino with USB-Hostshield or something similar... ( I'm using an Arduino MEGA ADK) Then we "simply" have to flash my code onto it and that should be it... (for the Arduino and qs part at least)
The Multi Module has to be flahed with the multi-stm-ppm-aetr-v1.3.2.86.bin firmware (even while there's an updated version, cause i know only for this ver that it works for sure)
Of course the Controls are using the Analog stick... everything else wouldnt be this fun ^^
