Bit of a longshot here but does anyone own a TEAC CD Player or Amp and have access to an IR decoder?
I got an MC-D78 on the cheap because the CD drive was broken, no issue because I'm going to plug it into a Bluetooth receiver.
It also didn't come with a remote, but that wasn't supposed to be an issue for me since it Japanese it probably uses NEC protocol and I have a fair amount of experience with that and could come up with an alternative.
I bought a simple programmable remote from China which has the ability to 'learn' the codes and repeat them, for certain buttons.
I could find the codes needed using a DIY transmitter, then use that to program the Chinese remote, once I knew the codes it needed.
I setup an Arduino and programmed it to scroll through every NEC IR code combination (takes about 2 hours), the theory being when the amp turns on, i would know the successful code.
Only issue is that it reaches the end of all the possible commands and ... nothing.
I know my transmitter works because it can control my Yamaha amp, satellite box and HDMI switch (all known to use NEC protocol since i have the remotes and checked them). I also know the IR receiver on the amp works because i scoped the output pin and could see the pulses i sent being received.
What I now consider is if it uses some other protocol, RC5, RC6 or just raw values.
If anyone has a TEAC device and could 'sniff' the codes the remote is sending it might help me in the right direction.
Thank You
