> How is it built ? From a kit from Wouter ? No. Built my own. > Or from stuff you have digged up? Yes. > Anything else connected ? The whole target circuit... Whole lot of other stuff I digged up. :-) LEDs, LCD, dials, LM335, LM336. > What level/voltage do you have on the MCLR pin after > the programming (when it "hangs") ? ~0 volts. While running: 3.2V. Supply: 5.1V. I also discovered that at times, merely touching the multimeter probe restarts the circuit. Am I onto something here?
