Re: Consistent Encoder RPM Issues

Use a lower CPR encoder. We were running into resolution issues with the timer once the square wave's period got extremely small. Less ticks = bigger period = more resolution.

We get fairly good results with a retro reflective optical sensor pointed at a piece of tape on the shooter wheel. We got terrible results with a 32 CPR encoder. We are calculating RPM with Counter::getPeriod().
