DLN_SPI_MASTER_GET_DELAY_BETWEEN_FRAMES Command and Response

The DLN_SPI_MASTER_GET_DELAY_BETWEEN_FRAMES command is used to retrieve current setting for delay between data frames on a single SS line.

DLN_SPI_MASTER_GET_DELAY_BETWEEN_FRAMES Command

Go to response

 typedef struct
 {
    DLN_MSG_HEADER header;
    uint8_t port;
 } __PACKED_ATTR DLN_SPI_MASTER_GET_DELAY_BETWEEN_FRAMES_CMD;

Parameters:

header

Defines the DLN message header DLN_MSG_HEADER. The header contains several predefined fields and is used to identify and route messages. You must fill the following fields before sending the command:

Field	Description
size	The size of the message. Must be equal to the size of the DLN_SPI_MASTER_GET_DELAY_BETWEEN_FRAMES_CMD structure.
msgId	Identifies the message. For the DLN_SPI_MASTER_GET_DELAY_BETWEEN_FRAMES command it must be set to 0x0225. You can use the DLN_MSG_ID_SPI_MASTER_GET_DELAY_BETWEEN_FRAMES constant.
echoCounter	Can be used to link a command to a response. The response will have the same echoCounter value. This field can be any numerical value from 0 to 0xFFFF (65536).
handle	A handle to the DLN-series adapter.

port

A number of the SPI master port to retrieve the delay setting from.

DLN_SPI_MASTER_GET_DELAY_BETWEEN_FRAMES Response

Go to command

The adapter sends the DLN_SPI_MASTER_GET_DELAY_BETWEEN_FRAMES response after the DLN_SPI_MASTER_GET_DELAY_BETWEEN_FRAMES command execution. The response contains current setting for delay between data frames on a single SS line.

 typedef struct
 {
    DLN_MSG_HEADER header;
    DLN_RESULT result;
    uint32_t delayBetweenFrames;
 } __PACKED_ATTR DLN_SPI_MASTER_GET_DELAY_BETWEEN_FRAMES_RSP;

Parameters:

header

Defines the DLN message header DLN_MSG_HEADER. The response header contains the following fields:

Field	Description
size	The size of the message. It is equal to the size of the DLN_SPI_MASTER_GET_DELAY_BETWEEN_FRAMES_RSP structure.
msgId	Contains the message id. For the DLN_SPI_MASTER_GET_DELAY_BETWEEN_FRAMES response it is set to 0x0225. The DLN_MSG_ID_SPI_MASTER_GET_DELAY_BETWEEN_FRAMES constant can be used to check the message ID.
echoCounter	Links a command to a response. The echoCounter value is copied from the respective command header.
handle	A handle to the DLN-series adapter. You can use the handle field to determine the adapter that have sent the response.

result

Contains the result of the command execution. For DLN_SPI_MASTER_GET_DELAY_BETWEEN_FRAMES command DLN-series adapter can return the following result values:

Return Code	Description
DLN_RES_SUCCESS	Current delay setting has been successfully retrieved.

delayBetweenFrames

Current delay value in nanoseconds.
