Function Documentation

◆ SPI_DirectlyTransmitReceiveData()

STD_RETURN_TYPE_e SPI_DirectlyTransmitReceiveData	(	SPI_INTERFACE_CONFIG_s *	pSpiInterface,
		uint16 *	pTxBuff,
		uint16 *	pRxBuff,
		uint32	frameLength
	)

Transmits and receives data on SPI without DMA.

This function can be used to send and receive data via SPI. SPI communication is performed in blocking mode but setting/resetting chip select and locking of the peripheral is not handled by this function. This must be ensured by the caller.

Parameters

pSpiInterface	pointer to SPI interface configuration
pTxBuff	pointer to data that is transmitted by the SPI interface
pRxBuff	pointer to data that is received by the SPI interface
frameLength	number of bytes to be transmitted by the SPI interface

Returns: status of the SPI transfer

Definition at line 162 of file spi.c.

◆ SPI_Lock()

STD_RETURN_TYPE_e SPI_Lock ( uint8_t spi )

Locks SPI interfaces.

This function is used to change the state of the SPI_busy_flags variable to "locked".

Parameters

spi	SPI interface to be locked (0-4 on the TMS570LC4357)

Returns: STD_OK if SPI interface could be locked, STD_NOT_OK otherwise

Definition at line 403 of file spi.c.

◆ SPI_TransmitData()

STD_RETURN_TYPE_e SPI_TransmitData	(	SPI_INTERFACE_CONFIG_s *	pSpiInterface,
		uint16_t *	pTxBuff,
		uint32_t	frameLength
	)

Sends data on SPI without DMA.

Parameters

pSpiInterface	pointer to SPI interface configuration
pTxBuff	pointer to data that is transmitted by the SPI interface
frameLength	number of bytes to be transmitted by the SPI interface

Returns: status of the SPI transfer

Definition at line 100 of file spi.c.

Here is the call graph for this function:

◆ SPI_TransmitDataWithDummy()

STD_RETURN_TYPE_e SPI_TransmitDataWithDummy	(	SPI_INTERFACE_CONFIG_s *	pSpiInterface,
		uint32_t	delay,
		uint16_t *	pTxBuff,
		uint32_t	frameLength
	)

Sends data on SPI without DMA, with wake-up byte.

It calls SPI_SendDummyByte() to wake-up the SPI interface.

Parameters

pSpiInterface	pointer to SPI interface configuration
delay	delay to wait after dummy byte transfer
pTxBuff	pointer to data that is transmitted by the SPI interface
frameLength	number of bytes to be transmitted by the SPI interface

Returns: status of the SPI transfer

Definition at line 121 of file spi.c.

Here is the call graph for this function:

◆ SPI_TransmitDummyByte()

STD_RETURN_TYPE_e SPI_TransmitDummyByte	(	SPI_INTERFACE_CONFIG_s *	pSpiInterface,
		uint32_t	delay
	)

Sends a dummy byte to wake up the SPI interface.

Parameters

pSpiInterface	pointer to SPI interface configuration
delay	delay to wait after dummy byte transfer

Returns: status of the SPI transfer

Definition at line 77 of file spi.c.

Here is the call graph for this function:

◆ SPI_TransmitReceiveData()

STD_RETURN_TYPE_e SPI_TransmitReceiveData	(	SPI_INTERFACE_CONFIG_s *	pSpiInterface,
		uint16 *	pTxBuff,
		uint16 *	pRxBuff,
		uint32	frameLength
	)

Transmits and receives data on SPI without DMA.

This function can be used to send and receive data via SPI. SPI communication is performed in blocking mode and chip select is set/reset automatically.

Parameters

pSpiInterface	pointer to SPI interface configuration
pTxBuff	pointer to data that is transmitted by the SPI interface
pRxBuff	pointer to data that is received by the SPI interface
frameLength	number of bytes to be transmitted by the SPI interface

Returns: status of the SPI transfer

Definition at line 138 of file spi.c.

◆ SPI_TransmitReceiveDataDma()

STD_RETURN_TYPE_e SPI_TransmitReceiveDataDma	(	SPI_INTERFACE_CONFIG_s *	pSpiInterface,
		uint16_t *	pTxBuff,
		uint16_t *	pRxBuff,
		uint32_t	frameLength
	)

Transmits and receives data on SPI with DMA.

This function can be used to send and receive data via SPI. SPI communication is performed in blocking mode and chip select is set/reset automatically..

Parameters

pSpiInterface	pointer to SPI interface configuration
pTxBuff	pointer to data that is transmitted by the SPI interface
pRxBuff	pointer to data that is received by the SPI interface
frameLength	number of bytes to be transmitted by the SPI interface

Returns: status of the SPI transfer

◆ SPI_TransmitReceiveDataWithDummyDma()

STD_RETURN_TYPE_e SPI_TransmitReceiveDataWithDummyDma	(	SPI_INTERFACE_CONFIG_s *	pSpiInterface,
		uint32_t	delay,
		uint16_t *	pTxBuff,
		uint16_t *	pRxBuff,
		uint32_t	frameLength
	)

Transmits and receives data on SPI with DMA.

This function can be used to send and receive data via SPI. SPI communication is performed in blocking mode and chip select is set/reset automatically. A dummy is sent first.

Parameters

pSpiInterface	pointer to SPI interface configuration
delay	delay to wait after dummy byte transfer
pTxBuff	pointer to data that is transmitted by the SPI interface
pRxBuff	pointer to data that is received by the SPI interface
frameLength	number of bytes to be transmitted by the SPI interface

Returns: status of the SPI transfer

◆ SPI_Unlock()

void SPI_Unlock ( uint8_t spi )

Unlocks SPI interfaces.

This function is used to change the state of the SPI_busy_flags variable to "unlocked".

Parameters

spi	SPI interface to be unlocked (0-4 on the TMS570LC4357)

Definition at line 418 of file spi.c.
