how can i generate variable pulse waveform using PWM outputs of 7344.

Hi
I want to generate a pulse waveform using the pwm outputs of 7344. How can i very the frequency of the PWM programatically.

If you are programming in LabVIEW, you can use the Configure PWM Output VI to set up the frequency of the pulse train. If you are in any other language, you can use the NI-Motion API and call the flex_configure_pwm_output function to achieve the same result. Please refer to the NI-Motion C reference help that gets installed with the NI-Motion 6.0 driver or follow this link:

for more information on this function.

Hi
I can use the PWM output only for the frequencies that is specified like 40Khz or 20KHz. I require to set the PWM frequency programatically to the desired value at a aduty cycle of 50%. How to implement this.

The motion controller does not have that capability, you will need to use something like a FieldPoint PWM module or a DAQ board with counter timers to do that.
