Simple bit of code to change the state of the GPIO pin 1 dependant on what GPIO pin 0's state is. However, using the BSF and BCF instructions don't seem to set GPIO 0's state when stepping through the debugger? I'm confused as to what the issue is here? Any help as I'm really new to PIC assembly language.

 

Did you notice that GPIO bit 0 is tristated in 18 and 19? Thus it doesn't react on output write commands.

Okay I see, I could only change the state of GP0 using the stimulus tool in MPLABX when debugging. I also have another question but I think I'll close this thread and open a new one with a better explanation of my issue- thank you though.
