Peter,
I haven't really though of it too deeply, but my thoughs are to time the durations of the high and low pulses by altering my capture edges everytime I get a new capture. And when I get a total capture time equals to 10 bit, then I know I've got a byte. But the problem is capturing the stop bit, which I do not know how to do without using another timer. It would be nice if I can setup my capture to be expired after a set time.
That's why I was asking if anyone has done it.
