These are just my notes, and described process worked for me on my 1C robot
If anything goes wrong, having USB adapter for FEL flashing might be the only way to restore your robot
this is not an official guide
oh, and I'm not responsible for any damage blah blah
and huge thanks to Dennis and Hypfer, and everyone behind this root :)

0. get uboot shell

to enter uboot shell on 1C you have to: 0. turn robot off normally

PyGame-based Valetudo Gamepad Remote Control

Uses PyGame, so it should work with all gamepads that work in actual games.

Nasty code ;)

It requires the gamepad to have at least one analog stick.

Modify the script and set DRY_RUN to True to avoid contacting Valetudo during gamepad testing.

/* Melbus CDCHGR Emulator
 * Program that emulates the MELBUS communication from a CD-changer (CD-CHGR) in a Volvo V70 (HU-xxxx) to enable AUX-input through the 8-pin DIN-contact. 
 * This setup is using an Arduino Nano 5v clone
 * 
 * The HU enables the CD-CHGR in its source-menue after a successful initialization procedure is accomplished. 
 * The HU will remove the CD-CHGR everytime the car starts if it wont get an response from CD-CHGR (second init-procedure).
