Tachometer Interrupt Help

[loafdog]

twiggzee, have you tried different speeds when running your device/tach? We found that until our shooter reached a certain speed getPeriod returned infinity. We also used setMaxPeriod to adjust the period so that we could measure shooter revolutions at the lowest speed we would ever use.
I didn't see a way to find out what the original max period value was, either by calling a function or looking at wpilib src code.
