I have a Desk Top computer that employs Windows 7.
I have MPLAB V8.92 and have an unusual problem with a programme I am currently writing.
Using MPLAB SIM, I cannot see any change to PORTA in the Watch Window when I attempt to simulate an output change.
Below is a sample of the code. After executing bsf rly, there is no change to PORTA.
I set TRISA to make RA4:0 outputs.
I had this problem several years ago with another programme I was attempting to stimulate, but unfortunately, I can't recall what I did to fix it.
I have explored the options in MPLAB but cannot find anything that will fix the problem.
I even used Control Panel to repair MPLAB but that didn't make any difference.
Any assistance will be appreciated.
#define chk_sw PORTA, 0 ;applies +5V to switches
#define rly PORTA, 2 ;relay
#define buzzer PORTA, 3
ORG 0x00 ; processor reset vector
call init ;Initiate parameters
bsf rly ;operate relay
