Finding RPMs with encoder
I am trying to set up an encoder to tell me the RPM of a shooter, the encoder is a US digital s4t - 120 - 250 encoder and 4x decoding. I see the multiple ways to get information from an encoder (getRate(), getPeriod(), get()) but what should I use to find RPMs with this encoder. Also, I don't know what to set as my setDistanceperpulse(), is it asking for how far the motor will move per pulse and if so by what unit of measurement is it asking?
