Diseqc control anyone ?

I doubt you would get a reply unless the OP still receives notifications as his last post was back in 2014.

I have done it once using soundcard, not PBP

Thnks for the replies
Yes it seems that nobody has done something via a PIC solution
I found some example but with Arduino.
Objective is to have a Disecq transmitter not for sat station or LNB
but to program some switchs or drive (and control) an Antenna rotator !
the hardware link could be an ordinary coaxial (power and 22 Khz Disecq)
as usual, it is a project ... number xx ... hi !!!

There are some speciality devices, which can do that.

some details please ....
thanks

Hi,
Am I correct in that "all it is" a 22kHz carrier modulated 0.5ms ON, 1.0ms OFF for a logic one and 1.0ms ON, 0.5ms ON for logic zero? How critical is the 22kHz and how critical is the on/off times?

Doesn't sound too hard to do with a PIC, much like a IR remote. The CCP moudle can generate a 22kHz tone which you can modulate with software by simply truning the signal on and off. You need external filter and attenutation+buffer to get the 0.65V peak-to-peak sinewave carrier.

With that said, I've got no experience with Diseqc, this is the firts time I've looked at it.

I think this PDF has enough information to create a PBP encoder/decoder. Like Henrik said, it looks a lot like IR remote control format. Very low bit rate.
