avi,
don't give up; I say don't give up.
I was the guy of the same way. My PICKit 2 was not working, so sad about that, I worked through lonely days and nights, but that won't worked......
But just a small idea, make it working. I just swapped the D+ and D- lines.....And it worked just fine.....But it giving a Vpp error stll for the inductor...
MVS will help me out from here. MVS, I'm really sorry, I was out of my home for a week, so I was unable to reply regarding the 680 uH inductor. I got a 470 uH; I'll try with ya and in a new PCB because my old PCB is just getting dirty and dirty....even it was not coated... If that do not work, as you said, I'll say you to send the inductors...I'll give you my postal and ph no soon....
OK??
for avi,
u should check the USB voltage smoothing caps. the 100 uF and 0.1 uF.
try swapping the D+ and D-, if you didn't done it before.
I programmed my 18F2550 eith ART2003, and my PK2 was detected by MPLAB without any hassle in winXP even in winvista. Who said, ART2003 will not work? It's simply not true.
avi, if you have a PK2 lite PCB, giimme the layout...
post images of yoiur PK2 board.
I gonna make the PK2 lite for experiment...
Let us work together
