Hello, I have try many times to understand how the quadrature encoder work so I can count a speed or steps of dc motor.
can any one Explain how can I use these encoder for count speed ??
To just measure the speed of a motor one doesn't need to use both A and B signals of a quadrature encoder. Just reading one of the 2 channels and knowing the number of pulses per revolution (from datsheet) one can just measure the counts generated within a specific 'gate' time, in effect you just measure the frequency of just one of the signal inputs to determine motor speed.
