CHIP: LPC11xx UART Driver blocking transfer functions

Detailed Description

These functions provide data transmit and receive via the UART and will block until the all the data has been sent or a specified amount of data has been received.

Functions
int	Chip_UART_SendBlocking (LPC_USART_T *pUART, const void *data, int numBytes)
	Transmit a byte array through the UART peripheral (blocking)
int	Chip_UART_ReadBlocking (LPC_USART_T *pUART, void *data, int numBytes)
	Read data through the UART peripheral (blocking)

Function Documentation

int Chip_UART_ReadBlocking	(	LPC_USART_T *	pUART,
		void *	data,
		int	numBytes
	)

Read data through the UART peripheral (blocking)

Parameters

pUART	: Pointer to selected UART peripheral
data	: Pointer to data array to fill
numBytes	: Size of the passed data array

Returns

The size of the dat array

Note

This function reads data from the receive FIFO until the passed buffer is completely full. The function will block until full. This function ignores errors.

int Chip_UART_SendBlocking	(	LPC_USART_T *	pUART,
		const void *	data,
		int	numBytes
	)

Transmit a byte array through the UART peripheral (blocking)

Parameters

pUART	: Pointer to selected UART peripheral
data	: Pointer to data to transmit
numBytes	: Number of bytes to transmit

Returns

The number of bytes transmitted

Note

This function will send or place all bytes into the transmit FIFO. This function will block until the last bytes are in the FIFO.
