Hi,

suddenly, every time I want to reprogram my PIC; it seems that it has been erased:



The other tab says:




I am using CCS IDE for windows. What can be wrong? It seems that I cannot overwrite the PIC's code. Code protect?! How did I get in that mode? How can I exit that mode?

Now it seems that my PIC is dead 10$ @#||@#

2. Run the PIC at +5v and Erase the PIC.

Thx for support, I did a reprogram with full erase @5V on ICD.exe. Then I could reprogram the PIC @3V.

Do you know by any chance how you can come in this situation?

You cannot reset the fuses at 3 volts.

How can the fuses be set in a way you don't want them to?
