Greetings from 2603; just a few quick questions. I searched and could not find all the information I need; if I missed it, I apologize; I don't want to waste anyone's time.

We have our KoP encoders mounted on our prototype chassis using AndyMark ToughBoxes and AndyMark encoder mounts. Since these were in the KoP, I was expecting there would be some sort of documentation about the sensors; I have not been able to find this -- only the documentation for the accelerometer and gyro -- not even on the OEM's page for the encoders, so I cannot find the number of pulses per revolution. The OEM's page (http://www.usdigital.com/products/encoders/incremental/rotary/kit/e4p/) says that it will have 400-1440 PPR; is there anything more specific, or a way to set this? Additionally, I see in the documentation for the Encoder class for C++ that we can use the pulse width in microseconds; is this information a viable alternative to the number of pulses to determine RPM, or, what is it useful for?

Thank you for your time!

There is some info (including part #) on this Andymark page (http://store.andymark.biz/am-0174.html) Using the part # you should be able to find any information you need on the manufacturers page (http://www.usdigital.com/products/encoders/incremental/rotary/kit/e4p/).

There are 250 pulses per rev on the encoder.
