HELLO,
HOW CAN I VERYFY a progrmmer be good or bad?
after reading the hex file from the chip,
the hex file from the compiler seems identical to that of re-reading from the chip.

in other articles in the forum also mentioned this.
such as mplab rewrite a new way of writing fuses

CONFIG FOSC = INTIO67, FCMEN = OFF, IESO = OFF
instead of
__CONFIG _CONFIG1H, _FOSC_INTIO67_1H &..
when the compiler compile the pbp file which 1 is included
i add the second way to the beginnig of a program:
__CONFIG _CONFIG1H, _FOSC_INTIO67_1H &..
is that the reason the program to be shut down?
any help i do appriciate,
thks
