Re: [Usbpicprog-technical] Problem with 16F628A

[Marcel K. <mak...@gm...>]

Hello Frans,

I just wanted to report back that adding a 470uF cap to VDD of P1, as
Marcelo suggested, did the trick. Now I was able to programm a 16F628A
just fine. For me the mentioned extra 100nF at the gate of Q1 was not
needed.

Best
Marcel
