[Ioannis]

are your cable longer than 15-20 cm?

Got it worked out!

Again a probably another rookie mistake...Solution was to increase the VDD to 4V! minimum. (software does recommend 4.5V) but 4 seemed to work fine.


Thanks Ioanins for the pickit3 plus software recommendation! That's what discovered the problem.
Great little program, works heaps faster then MPLAB X pck3md
Also integrated within MCS using the pickitcommand exe, hence can delete the bloated software MPLAB X!

My 5 spare 12F508 are breathing a sigh of relief!

Big thanks again,

Rob.
P.S Ioanins I'm coming to your lovely country next week for Holis, by any chance will you be in Athens on the 10th July? I owe ya a beer!!!

Glad you got it working!

Yeah, that stand alone revive of Pickit application is my favorite! Love it! Fast, compact and easy to use.

I think you cannot ged rid of the MPLABX as the PBP needs the assembler and the related files.

A beer would be very nice to have together but unfortunately I am about 560Km north of Athens. My town is Thessaloniki (second biggest own in Greece). Hope you visit places near the sea side or islands and feel the greek summer thing! Really hot here! Wish you a pleasant stay and if you like ancient places, Acropolis and the museum of Acropolis is a must to visit.

I'm heading to the islands. Maybe another time!

Completely removed mpab x and no probs to compile.

The programming spec document for the 12F508 states that the min VDD for programming and bulk erase is 4.5V, so I'd increase that just to be safe.

Once I realised it was the issue, went looking and found exactly that. Thanks.
