    Hi Debajyoti, the word “ticks” above refers to the pulses that we observe on the encoder. For example, if the desired speed I 1000 rpm and the encoder precision is 512 pulses per revolution, then we the expected number of pulses is 1000rpm * (0.0032/60)minutes * 512 pulses/rev = 27 (approx.). Hence we would set the OCR to 27 for this example.

    would you please explain what are you referring to by “ticks” .. . in ” We set our target in the OCR as the desired number of ticks we want in 3.2 ms.” ..
