Encoder Edges to Angular Displacement Readout

Hi NI! (This will be my first post.)

I have an encoder setup where I just want to read the leading edges of signal A (from an encoder. As the encoder is turned, I want to be able to find an angular displacement, which I believe there is already such a selection in LabView.

Modifing the example: Read Encoder. VI, I am still not able to get my edges to translate into a time-series of displacement...Any advice at all to give?

I'm using an onBoard clock on the cDAQ -9178 with a NI 9402 Digital I/O module.

Thank you!
