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
• version for 2 8bit timers, has, but if it still works is questionable:
• ARDUINO headphones support
• ARDUINO headphones single button support
• bluetooth support for modules with AT commands (ovc3860 based: XS3868, S3860M-S, BLK-MD-SPK-B), BK8000L - one way only, no feedback from module - TODO
