Re: [Usbpicprog-technical] PIC18F1220 VPP question

[Goncalo C. <gon...@gm...>]

That worked just great, at least with the 18F4550, I'll try with the
18F1220 later on.
Thanks

-----------------------------
This 4k7 to VPP is the problem, because usbpicprog has a 2k2 from the
generator to the output.
Please connect a diode + this 4k7 in stead:

VDD -----|>|-----|||||-----VPP_target

Cheers,

Frans
