I have setup in Pikdev the Pin assignments for this programmer: Vpp 8 (D6) Not inverted Vdd 2 (D0) Not inverted Clock 6 (D4) Inverted Data In 10 (/ACK) Inverted Data Out 5 (D3) Inverted Data R/W 25 (NA) Not inverted When I did pin tests I measured voltage on: Vpp/MCLR: but there is always 0V PGC but there is always 4.98V PGD but there is always 4.95V regardless I turned voltage on or off for these pins. :( The PIC 18F4550 intentionally isn't there on this protoboard jet. On C of the C556B PNP tranzistor measured 12.09V on B measured 11.97V on E measured 0.00V On C of the BC548B NPN tranzistor measured 0.00V on B measured 0.73V on E measured -0.00V Well, how can I programme with this Programmer the PIC F184550 as a jumpstarter when the measured voltages in pin test are not the right? Any advices will be appreciated! -- Regards, Paul -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
