Pickit3: EEPROM erased while reading device

Post by Dillon » Mon Mar 06, 2017 11:16 am

Hello all,
PIC16F887
I've made this test:
1)Program some EEPROM cells with fixed values, inside my program, and delete this portion of code
2)In the same program, read EEPROM cells: if values match with programmed ones, blink led
Ok, it works: even if I reprogam (preserving EEPROM), the LED blinks.
3)Read device memory

4)Led stops blinking

Any idea?
Thank you very much.

I think when you are reading your EEPROM then you are also clearing/deleting the data in it. Would you like to share the code so that I could help you out in better way.

I have also encountered with the error which is really disturbing for the EEPROM erased while reading device so you can D-link customer service and make changes in it. To detect, the mismatch you can get the proper setting which mentions there.
