Using an internal sample clock with a digital input

[griff32]

I am using an encoder to measure angle and velocity. The example that I have started with is here. https://decibel.ni.com/content/docs/DOC-6834. The problem I am having is with the Sample clock, I get a timeout at the DAQmx read. If I remove the sample clock the VI runs fine, but I have no idea of my sample rate. Below is the the problem setup with the Sample clock inline.

Hi there, a couple suggestions: first , this is a post that it is suppose to be on the DAQ board. Second, you are not being clear about the error, try to include the error code, description and its location, is it coming out of the channel node or the timing VI? Also what hardware are you using?

Now, If you open the example called "Measure Angular Position.vi" from the NI example finder, drill the DAQmx Create Channel, you will see that you are missing a couple terminals for the task configuration, I wonder if this is part of the error.
