Hi All,
I’m sure there’s a simple answer for my question, but I haven’t been able to
figure it out. Currently the configuration for the spindle forward and reverse
outputs is as follows:
# connect spindle fwd/rev to I/O controller
net SpindleFwd <= ppmc.2.dout.00.out
net SpindleFwd => spindle.0.forward
net SpindleRev <= ppmc.2.dout.01.out
net SpindleRev => spindle.0.reverse
I would like to selectively reverse direction depending on whether a backgear
input switch is triggered. I see there is a gearchange component but I’m not
clear on how to utilize it. Does the gearchange component translate to the pin
assignments for spindle.0.forward and spindle.0.reverse? Don’t I need some
additional logic? The goal is to have logic like so:
if (backgear == TRUE) {
net SpindleFwd <= ppmc.2.dout.00.out
net SpindleFwd => spindle.0.forward
net SpindleRev <= ppmc.2.dout.01.out
net SpindleRev => spindle.0.reverse
} else {
net SpindleFwd <= ppmc.2.dout.01.out
net SpindleFwd => spindle.0.forward
net SpindleRev <= ppmc.2.dout.00.out
net SpindleRev => spindle.0.reverse
}
As you can see, the only change is that I’m swapping which output is assigned
to spindle.0.forward and spindle.0.reverse.
Thanks,
Matt
