am-2899 Absolute Encoder

I am definitely not a battery or battery charging expert (far from it) but I do know enough to be dangerous (I stayed in a Holiday Inn Express last night)... - Don Wright [more]

The am-2899 (US Digital part number MA3-A10) has analog output, not PWM, and must be wired to an analog input.

The MA3-P10 (and -P12) have PWM output.

The FPGA, sampling at 40MHz, certainly is fast enough to detect and accurately time-stamp the edges of a PWM signal, but the FRC FPGA code does not support PWM decoding.
