Generate a Continuous Digital Pulse Train With a Variable Duty Cycle

[smam0008]

Hello guys I am currently trying to generate a continuous digital pulse with variable duty cycle. I have managed to do this thing on frequency but would like to do the same with the duty cycle. Any help please ?

Hi smam0008,

 We have a number of available example programs about using pulse-width modulation (PWM) with DAQmx, including modifying frequency and duty cycle while tasks are running. I'll link a few of them below as well as a general resource on PWM.

• PWM Dynamic Duty Cycle with DAQmx Write
• Counter Output PWM with Dynamic Duty Cycle Updates
• Generate a Continuous Digital Pulse with Variable Frequency (you can use this as a base for varying duty cycle)
• Generate a Continuous Digital Pulse with On The Fly Frequency Control
• General: PWM with DAQmx
