Do somone here have a ASM code for pic generating CCIR and ZWEII tones??
A google search for ZWEII brings up a whole load of games and your post. So it might be helpful if you explain what you are trying to do, as it is probably not much different to any other tone generation.


CCIR code are simple solid tones, more than enough information on how to do that already exists. No idea what ZWEII is though.

It is superficially related to the German word for "two". Could this be just good old DTMF?
