How to change SPWM Frequency of Arduino mega 2560 with MATLAB SIMULINK

Hello, I have problem with my project. I use Arduino mega 2560 and Simulink. For the control I need a Sinusoidal PWM (SPWM) signal with 10 kHz - 20 kHz but the output SPWM on Arduino takes the frequency of sine wave only.

What can I do?

I would welcome your response

Hi yahya,

The output pulses from your Simulink model appears to be generated with frequency of "sin wave" so this is why the arduino outputs the sin wave frequency pulses.

You can refer to the below model which outputs the SPWM signals at 1050Hz
