STM32H735G-DK sine wave

[kuxiang]

Hello,

I have referred to the tutorial documents from the University of Texas at Austin and I am using STM32CubeIDE. I generated a 1V amplitude 10kHz sine wave using a signal generator. After processing it through STM32H735G-DK, I observed a 10kHz sine wave with an amplitude of 0.6V on the oscilloscope. I am unsure of the errors in the code and unable to find a solution.

Hi @kuxiang,

Welcome to ST Community!
I suggest you double check the steps you followed referring to the following knowledge articles:

• How to generate a sine wave using PWM and RC filter - part 1
• How to generate a sine wave using PWM and RC filter - part 2

For sure you can replace the NUCLEO-G070RB by your own board in the steps of the tutorial.
