Syntax

C/C++

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

Parameters

handle: A handle to the DLN-series adapter.
port: A number of the UART interface port.
size: The size of the message buffer. This parameter is specified in bytes. The maximum value is DLN_UART_MAX_TRANSFER_SIZE (256 bytes).
buffer: A pointer to an array of unsigned 8-bit integers. This array will be filled with received data during the function execution.
actualSize: A pointer to an array of unsigned 16-bit integers. This variable will be filled with actual data size value.

Return Value

DLN_RES_SUCCESS: The operation completed successfully and data has been read.
