Hello there!
I try to find fans of PIC-micros and Pickit2.
I have some problem with my clone Pickit2. I have also original PICKIT2 and PICKIT3 (because some PICs do not program any more wirh PICKIT2).
I have made my PC Start device (http://remotesmart.wikidot.com/pc-start) some times, but about two days then PK2 says after programming "Verifying Fail".
And it really program badly to my board, I tried my software.
I tried to start my PC (Win10) again, no help.
Then I tried with old XP, no help.
Then I tried to change my PIC (PIC16F88) at my board, no help.
Then I tried with original PICKIT2. Yes, it worked ok. I programmed without power.
Then I open PICKIT2 (fail one) and using Tools/Troubleshoot I tested the PK2. Everything was right.
Then I looked the Tool/Calibration and it seems to be right (4.00V).
I donwloaded a new operating system, no help.
In the programmer there are two 8 bit memory chips (i2c 24LC512). Can they be somehow wrong?
There are some electrolytic capacitors also, is any body found them faulty?
The device is only two/three years old.
Also I looked the 5 pins to CPU, but they seemed right.
The programmer chip PIC18F2550 can be also bad, but it accept a new sowfware.
Can sombory suggest other methods?
