DlnSpiMasterSetDelayBetweenFrames() Function

The DlnSpiMasterSetDelayBetweenFrames() function sets a delay between data frames exchanged with a single slave device. For more information, read SPI Delays.

Syntax

C/C++

DLN_RESULT DlnSpiMasterSetDelayBetweenFrames(
   HDLN handle,
   uint8_t port,
   uint32_t delayBetweenFrames,
   uint32_t* actualDelayBetweenFrames
);

Parameters

handle: A handle to the DLN-series adapter.
port: A number of the SPI master port to be configured.
delayBetweenFrames: The delay value in nanoseconds. If you specify an unsupported value, it will be approximated as the closest higher supported value.
actualDelayBetweenFrames: Actual set delay value in nanoseconds.

Return Value

DLN_RES_SUCCESS (0x00): The function successfully set the delay between data frames.
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_BUSY (0xB6): The SPI master is busy transmitting.
DLN_RES_VALUE_ROUNDED (0x21): The delay value has been approximated as the closest supported value.

Remarks

DLN-1 and DLN-2 adapters do not support delays between frames.

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