Question: if you have a macro like this:
#define OUT_TRG_LO PORTD &= ~0x04
And you want to call it with a pointer, how do you do that?
I have 5 lines that I want to turn off after a fixed time, so I am using a struct to hold the parameters and a timer tick to count the time. Then a timer expires I need to call the macro to turn off the output line. Or is there a better way?
