Hi i have PIC16F877A , i used PICkit 2 v2.61 to program this chip..
At the first time i made all the connections right , except i put a 4MHZ oscillator with the micro and on the programmer was writtern 20MHZ -- i didn't see that the first time -- ,, the PICkit identified the microcontroller and i tried to write a program but an error message "Verification of configuration failed" , i tried maybe 5 more times again with different hex files but the same error message occurred
Then i smelt something burning i put my hand on the microcontroller and it was burning !!!
I unplugged the programmer and the next day i tried again without putting the 4MHZ oscillator and the same message occured i searched on the internet & solved this message ( i guess ) .
When i wrote a very very simple program on it the PICkit said it was successfully written, but when i made the the connections it didn't work !!
so i am afraid that my microcontroller did burn
If there's a way to test the micro or something ??
Hope you give me good news
