README.md

radio_emulator: arduino (ATMEGAX8 boards only) based vw/audi/skoda/seat radio emulator, I made this to revers eng. on vwcdpic and improve arduino version of CDchanger

  • emulate RADIO DataOut signal
  • receive and print CD changer responce to serial console

serial output is 9600

commands:

  • next track button =
  • previous track button -
  • next CD ]
  • previous CD [
  • play/stop p
  • CD1 1
  • CD2 2
  • CD3 3
  • CD4 4
  • CD5 5
  • CD6 6
  • seek forward f
  • seek rewind r
  • scan mode s
  • shuffle mode l
  • help h

connectios:

  • DataOut -> arduino pin 12

  • Clk -> arduino pin 3

  • DataIn -> arduino pin 4

CDC_emulator: arduino based cd changer emulator for vw/audi/skoda/seat radios, based on avr port of vwcdpic(see header of file for more info)

current status (see readme inside dir):

  • tested with my old audi concert 1 radio, and RCD300 (only enable 1CD, TODO: make all 6CD works)
  • ARDUINO headphones support
  • ARDUINO headphones single button support
  • bluetooth support for modules with AT commands (ovc3860 based: XS3868, S3860M-S, BLK-MD-SPK-B) - one way only, no feedback from module - TODO
