PWM output on cDAQ-9178 Chassis PFI Line

Solved!
Go to solution

Hi,

 

The front panel of cDAQ-9178 Chassis comes with two built in BNC connectors identified as PFI0 and PFI1. My question is: can I use both of these to simultaneously access two of the onboard counters (housed in the Chassis), to generate PWM output for two BLDC motors? I know I can access the onboard counters using a Digital I/O module, but that's not what I am looking for. The Chassis PFI lines can be used for Counter Input, as shown here: https://forums.ni.com/t5/Example-Code/CDAQ-9178-Count-Digital-Events-Without-Digital-Module/ta-p/352.... But can they be used for Counter Output as well? And will I be able to change the duty cycle of the bldc motor while the program is running?

Is it possible to slow this down to a 125 Hz output?

If you read and run the example from the same link of How to Output a Digital Signal from a cDAQ PFI Chassis Terminal, you can change the output frequency.
