  Is there some list of troubleshooting points (checklist) so I can check why my programmer started to fail to program the eeprom portion of the PICs?

  I think that my programmer was faulty from the get-go since I've never needed to program PICs eeprom until now.

  I've replaced the 7812c with the new one so I'm getting the 12.01V accross the output and not the 11.8V as it was with the original one. As far as I see in the other posts I should have the ~13V on the output, but isn't the spec of the 7812 says that it should regulate 12V?

  Thanks for any advice.

There are some PICs with data EEPROM that require more time to program than is actually specified by microchip. The 16F248A is one example. What PICs are you having trouble with? It may be timing, I cannot remember a case that turned out to be the voltage level without it also affecting the code space. This is not gospel, just what I remember currently.

You can try increasing the "programdelay=" value in the chipinfo file in increments of 10 (dec). Just remember to quit and reload micropro after you have saved the changes.

Hello, raising the topic, I have only the hex file, with parts of EEPROM and get error in recording.how could I do?
The PIC recorder is a K150.
