I am trying to use PORTA of PIC16F877A as digital output port. But somehow it does not seems to be working.
I am using MPLAB X IDE MPASM to assemble the code. Below is the code I am using to initialize PORTA -
banksel PORTA; clrf PORTA; banksel ADCON1 movlw 0x06 movwf ADCON1 banksel CMCON movlw 0x07 movwf CMCON banksel TRISA movlw 0x00 movwf TRISA banksel PORTA movlw 0xFF movwf PORTA
The LEDs at the output does not glow at all. What am I missing? I am not expecting RA4 to glow as I know it requires an external pull-up resistor but what about other LEDs.
Any help would be much appreciated. Thanks in advance.
