    Motor Disk Encoder

    CaDu_3933941

      Hi all,

       

      I am attempting to read the speed of a dc motor using a disk encoder which causes an opto coupler to generate a square wave based on the slits on the disk.  My question is this:

       

      How do I read the frequency of the pulse train generated by the device?
