UartExample.vi demonstrates how to set and get properties values of UART port and call methods for transferring data through UART interface.
Application Block Diagram is shown below.
All components are connected sequentially and all error inputs and outputs should are connected. First, we call DlnConnect.vi component and connect to proper inputs port
and host
values. Then we call DlnOpenDevice.vi component, which opens any connected DLN-series device. DlnUartPort.vi gets Dln.Device
reference and port index number
as inputs and we get Dln.Uart.Port
reference as output. Connect Dln.Uart.Port
reference output to Property Node
to configure properties. To add port properties right-click on Port Property Node, choose Add Element, then right click again on the new element and choose "Select Property" list. After property is added you can change property to read or write by right-clicking on property element. Connect Dln.Uart.Port
reference output to Invoke Node
to execute available methods. In this example Write
method is called with buffer parameter as input.
After all operations with UART module are done, close Dln.Device
reference and finally call DlnDisconnect.vi to close connection with Dln Server and Dln.Library
reference.
