Measuring the angle of motor rotation using Encoder shaft and PIC 16f877a

[mohamed]

i want to know the the angle of rotation of a motor using the pulses coming from an encoder by using microcontroller PIC 16f877a
thank you

Count the pulses and the angle is #count / #ticks per rev * 360°.

Encoder pulses represent rotational translation, time is well, time.

So measure encoder pulses and time, then divide one by the other as said above and you get a speed value. Hell, with quadrature encoders you get a velocity.
