How to make working xc161cj uP with printer port wiggler on high speed PC? Board alone work fine, but OCDS not. PC is Athlon 2500. Please tell mi if anyone have experience. I spend tens of hours with experiments, with no success. OCDS signals viewed with oscilloscope is clear and well shaped.
Stefan, thank you for suggestions! Problem is solved: Pin 13 on printer port must be grounded! As seen inteface is not speed depenent, but depend on inplementation of printer port.
Hi Gyoergy, thanks for feedback. A good hint for next high speed troubles to solve. Stefan
