PWM with Low Frequency (less than 40 Hz)

[Hamoda.adel.924@gamil.com]

i'm using myRio to generate PWM signal. how can I get PWM frequency lower than 40 Hz, I would like to reach 10, 20, 30, 40 Hz

Hi,

In order to output a lower frequency PWM, you will need to use the FPGA. This example seems like it performs what you need. You will have to change the RT target in the project for the myRIO and also update the FPGA VI to use the myRIO's I/O but everything else is already done. http://www.ni.com/example/26726/en/
