PICsters, While we're on the topic of IR, I got a question that's baffled me for some time. I recently hooked up an IR detector (GPU125?) to my parallel port, and sampled it. I was able to rec'v the bit stream, but what I wondered was, WHEN do I start sampling? There are lots of things that I try to master on the parallel port -- because the results are instant, and it's easier. Then later I implement it on the PIC. Anyways, if I start sampling the port TOO soon, I'll just get back bunches of 0's, and if it's too late, I might miss something. And as usual, I very much appreciate everyone's knowledge! Thanks in advance, Tim H.
