Setting Up Clock UART RX TX Baudrate 9600

Hi Everyone!

I am using the STM32407IG and i am trying to send data to another mcu chip via USART RX TX Pins.

The Problem is when i run it via USB FS i don't get the baud rate adjusted.

How can i setup the Clock for a Baud rate of 9600?

That's my clock so far:

 RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_HSE;
 RCC_OscInitStruct.HSEState = RCC_HSE_ON;
 RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;
 RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE;
 RCC_OscInitStruct.PLL.PLLM = 8;
 RCC_OscInitStruct.PLL.PLLN = 192;
 RCC_OscInitStruct.PLL.PLLP = 2;
 RCC_OscInitStruct.PLL.PLLQ = 4;
 HAL_RCC_OscConfig (&RCC_OscInitStruct);

Here i have the baud rate in my code:

 UartHandle.Instance = USARTx;
 UartHandle.Init.BaudRate = 9600;
 UartHandle.Init.WordLength = UART_WORDLENGTH_8B;
 UartHandle.Init.StopBits = UART_STOPBITS_1;
 UartHandle.Init.Parity = UART_PARITY_NONE;
 UartHandle.Init.HwFlowCtl = UART_HWCONTROL_NONE;
 UartHandle.Init.Mode = UART_MODE_TX_RX;
 UartHandle.Init.OverSampling = UART_OVERSAMPLING_16;
	

Thanks for every help! :smiling_face_with_smiling_eyes:
