STM32-MAT/TARGET

OP (Company: HIL) #5985885
Hi, I am trying to generate sine modulated PWM on STM32F401-Disco board 
using MATLAB. The desired freq of a sine wave is 50Hz and of the carrier 
wave is 20kHz. But I am not getting 50Hz freq. Please suggest a 
solution.



I need sine modulated PWM during +ve half cycle of a sine wave and zero 
output during -ve cycle of a sine wave. Desired samples of sine are 200. 
I have attached the MATLAB simulation circuit snapshot. Problem is that 
I am getting 5Hz freq.
