Encoder Edges to Angular Displacement Readout

[Sensuisam]

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!

Hi Sam, welcome to the forums!

I'd advise you to try building a task in NI MAX, to make sure your hardware configuration is correct first. You can do this following the guide I linked to below. Note: this guide is for creating an analog input task, so you'll follow the steps up till step 4 when they choose analog input as their data type. Instead you will choose..

Counter Input > Position > Angular Position.
