Hi, I'm trying to program a 16F872 using LVP and so far only failed. I have searched the net and read MC docs (eg. ds39025e) but clearly i'm missing something. I have been using a VERY simple programmer Ludipipo style (whatever that means) with which I have programmed 16F84 lots of times. I thought that with some slight mods. this could be used to program the 87X. So far i have used PonyProg as PC programming sw. Can anybody direct me to schematics of a simple serial(PC) ICSP programmer or anything else that could help me going again.
