PIC programming: WinPic800 – Error; cannot erase and write

Asked By maria_pinili 0 points N/A Posted on - 09/24/2012

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.

WinPic800

ERROR -> Writing address 0x0001A8

Written : 0xE105 Read : 0xFFFF

PIC programming: WinPic800 – Error; cannot erase and write

Hello Maria,

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.

Regards,

Nicke
