#96506 - Decoding manchester with only capture in |
The problem: I have a manchester encoded signal - RC5. Rising edge in the middle of the bit cell for a '1', falling edge for a '0'. I have the use of a capture input on the PCA, so I can measure the time between the edges. From this I can deduce the following:- 1 bit time high 1 bit time low 2 bit time high 2 bit time low It's getting late at night and my brain is having trouble trying to sort out a nice, clean method of decoding the data. I would like the code to run off the capture input interrupt - therefore no delay loops or using another timer or compare channel. Sounds like a good reason to use a state machine! There must be a classical solution! |
