DlnSpiMasterGetDelayAfterSS() Function

The DlnSpiMasterGetDelayAfterSS() function retrieves the current setting for minimum delay between assertion of an SS line and the first data frame.

Syntax

C/C++

DLN_RESULT DlnSpiMasterGetDelayAfterSS(
   HDLN handle,
   uint8_t port,
   uint32_t* delayAfterSS
);

Parameters

handle: A handle to the DLN-series adapter.
port: A number of the SPI master port.
delayAfterSS: A pointer to an unsigned 32-bit integer that receives the current delay value in nanoseconds.

Return Value

DLN_RES_SUCCESS (0x00): The function successfully retrieved the delay after slave selection.
DLN_RES_INVALID_PORT_NUMBER (0xA8): The port number is not valid. Use the DlnSpiMasterGetPortCount() [1] function to find the maximum possible port number.

Remarks

DLN-1 and DLN-2 adapters do not support delays after slave selection.

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