I have the PIC kit3 and a 16f684 PIC micro controller, i have downloaded the lastest MPLAB, but get an error saying the chip isn;t identified, codes as all zeros, recognizes the PICkit3 but not the chip...expects a certain code but all zeros appear...what shall i do to configure the PICkit3 with the 16f684?

It continues to say device ID 00000000, not as expected device ID 00001080...finds the pickit3 but cannot find the device...i have found this same problem from others but haven't found the solution...i have a pull up resistor, 10K, to VDD as instructed...what am i missing here?

I have the same trouble that PICkit3 not work with old uControllers (especially with 16F684) and my solution was :... I use PICkit2. I do not know why but i have both now and when i can't use a PICkit3 then i try on PICkit2.

Best regards

interesting, i was just communicating that idea with a friend of mine, of course i thought newer was better, but, seems like, this isn't true with PICkits! what do you think about the Olimex clones?
thanks for the reply

Did you select the device correctly in Configure -> Select Device. It is not automatic.

yes definitely, went through the entire tutorial and also some suggestions online...seems to be a common problem. but have ordered the pickit2 so, hopefully that will remedy the situation...and there maybe more questions soon. thanks again
