WebbI have a motor, rated at 2600 Rpm and an encoder 256 counts per revolution. I count the ticks of the encoder with input interrupt and I also use a timer interrupt to take the difference between counts in 1 ms. If I spin at 2600 RPM, I would read 2600*256 = 665600 counts in 1 minute (60 seconds). So, in 1 second I read 665600/60 counts, which is ...
