UART_get_port_handle_by_name()

UART_HandleTypeDef * UART_get_port_handle_by_name

(

const char

port_name[]

)

Get the UART port handle by its name.

Parameters

port_name

Case-insensitive name of the UART port to retrieve the handle for.

Returns

Pointer to the UART handle structure for the specified port name, or NULL if not found.

Warning

This function MUST be checked for NULL return value before use.

UART_set_baud_rate()

uint8_t UART_set_baud_rate	(	UART_HandleTypeDef *	port_handle,
		uint32_t	new_baud_rate )

Set the STM32 UART peripheral's baud rate to a different value.

Parameters

port_handle	Pointer to the UART handle structure for the port to change the baud rate of.
new_baud_rate	The new baud rate to set the STM32 UART peripheral to (in bits per second). Common values are 9600, 115200, 230400, etc.
