Hi, I am working with a STM32H743 and I am trying to use USB OTG FS with the best clock configuration possible. I would like to have a SYSCLK at 480MHz and use the USB OTG FS with the external clock source HSE at 48MHz.The frequency of the external c...

Hi, I am currently working on the STM32H743 and i'm trying to bring data from SPI6 to a buffer in D2. As I have a lot of data to read i would like to use the DMA in order to transfer data without using the cpu. I don't understand whether I can use th...

Hi, I apologized for the delayed response, I tried another time the configuration I used : PLL1 for the USBclock and external clock as the clock source for SYSCLK. Here is the SystemClock_Config :void SystemClock_Config(void) { RCC_OscInitTypeDef RCC...

Hi and thank you for the fast reply, I tried the configuration you presented and my device is still not recognized.Like i mentionned above, when I try to change the USB clock source from HIS48, it stops working.

Still replying even if the message wasn't meant for me :)I didn't have the HSE_VALUE set to the correct value.I corrected it and it allowed me to use the external clock as the source clock for the SYSCLK (first issue solved).I tried to use the HSE fo...
