Hi Guys,
This code is for 16f628A @ 10 MHz to become an IR receiver for the Commodore CDTV remote.
Commodore had a lot of these manufactured before a new model CDTV that never happened,
and so plenty of new old stock is available from eBay.



The overlayed buttons in this image are mapped to pic IO pins, and they will be held low
for as long as the buttons are pressed.
Additionally, the CD player buttons can be read as well.
Some combinations entered on the keypad can also be used to configure the receiver.
For example, a certain keypad code (revealed in the source) will make the keypad
a DTMF keypad, and another will mute the beeps for CD track skip.

No schematic is available, but the IO pin definitions are given at the end of the code/

If anyone builds it, it’s probably a good idea to watch this series of videos starting with this one:

In the second part, I changed from the Sony remote, to the CDTV remote pictured here.
Cheers, Art.
