I tried to write a program in my PIC that was recently erased, and then it showed this error. I tried to read the content of the PIC and I was able to see the program that was supposedly erased before writing a new one in it. It looks like it became read only, how do I change it? I hope my PIC is still useful.
ERROR -> Writing address 0x0001A8
Written : 0xE105 Read : 0xFFFF
PIC programming: WinPic800 – Error; cannot erase and write
In the event that you made something yourself, in the Pic12f683 the programming high voltage is internally generated.
So for you to activate the Program/Verify mode, the high voltage will have to be applied to MCLR input. Since the MCLR is used for a level source, then the MCLR will not be able to draw any significant current.
So you will need to check your breadboard for any issues.
