Thanks for your reply. I have an oscilloscope. But I have searched everywhere in the board and I can’t find any pwm signal it’s so strange. I have checked every pin on the stm32 I can’t find a signal but he’s at 20kHz it’s too high for a pwm no? I found the same signal on each 3 power mosfet...

Hi all I’am looking for pwm signal on my h520e. I thought pwm signal was where I surrounded in my attachment file but I don’t have any signal here. I checked every pin on stm32f301 but I haven’t found any pwm signal. I can only found a square signal on each power mosfet at 20kHz
