Transfer myRIO PWM vi to NI DAQ PWM vi

[evanzou1996@gmail.com]

Hello, everyone. Previously, I use NI myRIO1900 to generate PWM signal. However, myRIO will be discontinued from next year. Can anyone tell how can I build the exactly the same PWM usingNI DAQ card? Many thanks.

Use a DAQ device with counter capabilities, then define a CounterOut task in DAQmx and define duty and frequency…

(DAQmx comes with example VIs to learn from!)

Dear GerdW,

I am not familiar with this part. Could you please give me some pictures? 

Many thank.

NI has just announced the "replacements" for the USB-600x series called mioDAQ.  There are four announced (USB-2421, -2123, -2451, and -2453).  Specs range from 16/8 or 32/16 (SE/DI), 16 (or 20) bit AI at 250 kS/s or 1MS/s, 2 or 4 AO, 16 DIO, and 4 (!!) Counter/Timers.  I think they are slightly more expensive than the much older DAQ devices they replace, but seem to have much better specs (and are USB-C).

This is the announcement and specs for the mio-DAQ.
