Function Documentation

int Stm32UsartSetStopBits

(

uint8_t

bits

)

Set the USART hardware to the number of stop bits.

This routine is called by ioctl function of the upper level USART driver through the USARTDCB jump table.

Returns:

0 on success, -1 otherwise.

References rc, USART_CR2_STOP, USART_CR2_STOP_1, and USARTn.

uint8_t Stm32UsartGetClockMode

(

void

)

Query the USART hardware for synchronous mode.

This function is called by ioctl function of the upper level USART driver through the USARTDCB jump table.

Not implemented for the STM32 USART. Always returns 0.

Returns:

Or-ed combination of UART_SYNC, UART_MASTER, UART_NCLOCK and UART_HIGHSPEED.

USART1 device information structure.

An application must pass a pointer to this structure to NutRegisterDevice() before using the serial communication driver of the AT91's on-chip USART1.

The device is named uart1.
