DlnSpiMasterSetFrameSize() Function

The DlnSpiMasterSetFrameSize() function sets the size of a single SPI data frame.

Syntax

C/C++

DLN_RESULT DlnSpiMasterSetFrameSize(
   HDLN handle,
   uint8_t port,
   uint8_t frameSize
);

Parameters

handle: A handle to the DLN-series adapter.
port: A number of the SPI master port.
frameSize: A number of bits to be transmitted. The DLN-series adapter supports 8 to 16 bits per frame.

Return Value

DLN_RES_SUCCESS (0x00): The function successfully configured the size of a SPI data frame.
DLN_RES_INVALID_PORT_NUMBER (0xA8): The port number is not valid. Use the DlnSpiMasterGetPortCount() function to find the maximum possible port number.
DLN_RES_SPI_INVALID_FRAME_SIZE (0xB8): The frame size is not valid. The DLN-series adapters support 8 to 16 bits per transmit.
DLN_RES_BUSY (0xB6): The SPI master is busy transmitting.

Remarks

The default frame size is set to 8 bits. To check the current frame size value, use the DlnSpiMasterGetFrameSize() function.

The DlnSpiMasterSetFrameSize() function is defined in the dln_spi_master.h file.
