I need to link a GPIO to a function block. I think I just need to point the address to the GPIO when the function block is initialized. Then control the output when needed.

Output 25 turns on just before the SPI transmits to the relay board then turns off afterward. I don't know what is used for, but I am going to follow what the creator of the relay board did.

Any suggestions?
