i want to output a pwm pulse, its duty cycle is varied according to addition of the two pwm pulse generated according to the sinusoidal pwm technique.

    Hello Archu,

    We need to know some more information

    1. What is the TIVA Device you are targetting it for

    2. Is there a response time requirement from the addition of the two input pwm pulses to output of the pwm pulse. Please note that TM4C devices do not have a arithmetic block to do it on the fly and would need CPU intervention so a delay in response would be expected.

    Regards

    Amit

    hi,

    thank you for your response.

    i am currently using tm4c123g.


    my current problem is that i want to generate a pwm signal with its duty cycle continuously changing.(changes according to the signal generated by adding two sinusoidal pwm signals). how can i implement this?.can i use the GPIO output as pwm signal?.

    Regards

    Archu

    Your description of your requirement (appears) to spectacularly exceed your time/effort in MCU manual read/review...

    Few sentences into the gpio section of that manual will answer your gpio output as pwm question.  (No)

    A large chapter - greatly detailing PWM set-up & operation - awaits those willing to do, (some) work...
