Friends, I am having a serious problem with a PIC project. I am using a PIC16C67 running at 2.4576MHz (TTL canned OSC.). Two of the I/O lines go through about 6 feet of wiring. The problem is that the lines are having problems with (I'm guessing!?) capacitance. I will use a very short cable and everything seems to work fine. I checked the long cable and there isn't problem with it. I am curious about how the PIC treats capacitance and hopefully some of the PICers out there can make a few suggestions. Any help would be greatly appreciated!! Thanks in advance!!!
