What is the refresh rate of the digital inputs on the DIO Module? Specifically, our team would like to use the kit encoders but are worried about the cRio being capable of tracking the encoder count on an axle with a high rpm.

Re: GPIO Refresh Rate
Digital inputs are sampled at 153kHz. That means that for a quadrature encoder, which has 4 edges per "pulse", the maximum pulse rate is 38,314 pulses per second.
