DlnSpiSlaveGetFrameSize() Function

The DlnSpiSlaveGetFrameSize() function retrieves the current size setting for SPI data frames.

Syntax

C/C++

DLN_RESULT DlnSpiSlaveGetFrameSize(
   HDLN handle,
   uint8_t port,
   uint8_t* frameSize
);

Parameters

handle: A handle to the DLN-series adapter.
port: A number of the SPI slave port.
frameSize: A pointer to unsigned 8-bit integer that receives the number of bits transmitted in a single frame. The DLN-series adapter supports 8 to 16 bits per frame.

Return Value

DLN_RES_SUCCESS (0x00): The function successfully retrieved the current frame size.
DLN_RES_INVALID_PORT_NUMBER (0xA8): The port number is not valid. Use the DlnSpiSlaveGetPortCount() function to find the maximum possible port number.
