Is the DMA overstrained? DMA & InputCapture Issues

Hi everyone, my setting looks like this:CPU CLK: 480MHzAHB CLK should be 240MHz (I'm not 100% sure)Timer CLK 120MHzInputCapture Channel: 4 (2 direct, 2 indirect)I generate 8 short pulses each about 30ns. I use 4 InputCaptures to read those pulses. 2 ...

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