Hello all,

I'm tinkering with a remote control transmitter and a Sharp IR receiver.
I have the PIC successfully receiving data from the IR receiver.  I had
planned on using the Capture feature (to measure pulse width) of the
16F628.  I've now got working code that uses the Capture feature, but I
have now discovered that the remote TX that I'm using sends the data
using biphase encoding.

I've thought about this for a bit and have come to the (erroneous?)
conclusion that the capture technique is probably not going to work.  My
question is, "what is the best way to decode biphase data?"  Does anyone
have an tips on doing it?  I've Googled my fingers numb, but haven't
found a "readable" piece of code that decodes biphase data.

I'm somewhat stumped as to how best to do this, since rising/falling
edges occur in the middle of the data bits.

Any tips or advice would be greatly appreciated.
