Can anyone help. I have a raspberrypi3 with a photoelectric sensor and a 600ppr encoder hooked up. Everything is up and running, im using pigpio to capture my pulses from the encoder and using the sensor measuring an object. The object im measuring is accurate to +/-5mm running at 300 meter/per/min. When I try to run above 400 meter/per/minute my reading on the encoder isn't very stable, would it help if I got a lower ppr encoder say 360?.
The calculation to work out if encoder is compatible is revs/per/second x ppr of the encoder . In my case 600ppr.
can anyone tell me what frequency the raspberrypi3 can handle?.
