I have a motor which drives a rack mechanism and I'm using a rotation sensor to
index my position on the rack.
When I program the motor (in NQC) to go forward I want the sensor to count up.
If the sensor then actually goes down I want to test for this condition and
correct it in software. This way I can index one end of the rack as 0 and the
other as whatever. Either the motor or the sensor could be the wrong way round.
To keep things simple I only want to switch the sensor connection not the motor
connection.
To do this I need to be able to flip the direction "forward" in the code, so if
the motor and sensor directions conflict I can correct this in software.
I tried to do this with a macro, but the compiler requires I use a constant and
not a variable. But as the test is done within the program I have to use a
variable.
So basically I'm looking for a replacement for OnFwd();
