    How to update duty cycle runtime?

    while generation of PWM whether is it requires to start and stop pwm?

    Please share if any reference for the above.

    using driver library for implementation

    //! This example uses the following peripherals and I/O signals. You must
    //! review these and change as needed for your own board:
    //! - Timer peripheral
    //! - GPIO Port peripheral

    //! This example uses the following interrupt handlers. To use this example
    //! in your own application you must add these interrupt handlers to your

    Hello,

    For future posts, please use a thread title that's more descriptive than just the part number of your device - summarize the issue or question. This will help others in our community find your threads more easily, especially if they have the same question. I've updated the title of this thread already.

    You can find out how many PWM signals can be generated from each Timer module by referring to Table 6-1. Device Comparison in the datasheet. See footnote (3) to understand how to interpret the numbers (e.g. 5, 3, 3). Basically, each number represents the number of possible PWM outputs per Timer instantiation.

    I think Leo already explained this in the following thread.
