I am doing a dc motor controller for positioning application..the encoder have been attach to the motor to sense the position of the motor. this project have 3 speed (which is mean have 3 different number of PWM).
So, my lecturer ask me to prove the three speed using an oscilloscope. so, how should i connect my hardware to the oscilloscope , to check the digital output from the encoder( it have 2 output). so 1 need to prove the speed with 2 quadrature waveform from the scope.
How should i link it? is it i need to link the oscilloscope with the PIC pin connection or from the encoder pin?
tq for helping me.
