DlnI2cSlaveLoadReply() Function

The DlnI2cSlaveLoadReply() function loads data to be transferred to an I²C master device.

Syntax

C/C++

DLN_RESULT DlnI2cSlaveLoadReply(
   HDLN handle,
   uint8_t port,
   uint16_t size,
   uint8_t* buffer
);

Parameters

handle: A handle to the DLN-series adapter.
port: A number of the I²C slave port.
size: A size of the data buffer to be loaded. The size is specified as a number bytes and can vary from 1 to 256.
buffer: A pointer to an array of unsigned 8-bit integers that receives data to be sent to an I²C master. The size of the buffer is specified in the size parameter.

Return Value

DLN_RES_SUCCESS (0x00): The function successfully loaded data to the buffer.
DLN_RES_INVALID_PORT_NUMBER (0xA8): The port number is not valid. Use the DlnI2cSlaveGetPortCount() function to find the maximum possible port number.
DLN_RES_BUSY (0xB6): The function cannot specify I²C slave addresses for the DLN adapter while the I²C slave port is busy transmitting data.
DLN_RES_INVALID_BUFFER_SIZE (0xAE): The specified buffer size is not valid.
