Hi,

Kindly attach your project files to investigate further. Check the following also.

  1. Make sure that you selected PIC 16F877A in the project settings. PIC 16F877 and 16F877A are different microcontrollers.
  2. You don’t need to check MCLR in the PICkit2 software
  3. You can uncheck Programmer >> Manual Device Select, PICkit2 will automatically detect the microcontroller. So you don’t need to select it manually.
  4. Make sure that the microcontroller you are using is PIC 16F877A not 16F877.
  5. If everything is correct, try using a new microcontroller ic.
