Multiple DAQms tasks for generate a CO Pulse Freq to control stepper motor speed

[raluca25]

Hello,

I have a potentiometer with who I want to change the duty cycle of a pulse signal to control the speed of a stepper motor. I am using National Instrument NI USB 6212 as data aquisition module. I created an Analog Input Voltage DAQmx channel to get the potentiometer voltage and an CO Pulse Freq DAQmx channel to generate the pulse signal. How can I use the potentiometer as a Trigger so every time I rotate the potentiometer the CO Pulse will trigger and change the duty cycle. 

I created the scheme for both of events but I can't figure it out how to connect them between themselves.

Thank you

I recommend exploring producer / consumer architecture. This is useful to share data between two loops running at potentially different rates.
