1.27.5.11 FLEXCOMx_USART_SerialSetup Function

C

/* x = FLEXCOM instance number */

/* Blocking, non-blocking and ring buffer mode */

bool FLEXCOMx_USART_SerialSetup(FLEXCOM_USART_SERIAL_SETUP * serialSetup, uint32_t clkFrequency)

Summary

Sets up serial configurations for USART peripheral.

Description

This function sets the serial configurations of the peripheral. It provides run-time interface to configure the baud, parity, stop bits and data character size parameters of the serial connection. Calling this function when a serial communication is in progress can disrupt the communication. The caller should ensure that there is no serial communication in progress. In case of success, the function will update all parameters specified in the serialSetup parameter, even if some parameter may have not changed since a previous call to this function. In case of failure, all parameters stay unchanged.

Precondition

FLEXCOMx_USART_Initialize must have been called for the associated USART instance. The USART transmit or receive transfer status should not be busy.

Parameters

Returns

true - Serial configuration was successful

false - The specified serial configuration could not be supported. This, for example, could happen if the requested baud is not supported.

Example

FLEXCOM_USART_SERIAL_SETUP setup = {
    115200,
    FLEXCOM_USART_DATA_8_BIT,
    FLEXCOM_USART_PARITY_ODD,
    FLEXCOM_USART_STOP_1_BIT
};

FLEXCOM0_USART_SerialSetup(&setup, 0);

Remarks

None
