SpiSlaveExample.vi demonstrates how to set and get SPI Slave port properties values and call methods for transferring data through SPI Slave Interface.
Application Block Diagram is shown below.
All components are connected sequentially and all error inputs and outputs should be connected. First, we call DlnConnect.vi component and connect to proper inputs
host values. Then we call DlnOpenDevice.vi component, which opens any connected DLN-series device. DlnSpiSlavePort.vi gets
Dln.Device reference and
port index number as inputs and we get
Dln.SpiSlave.Port reference as output. Connect
Dln.SpiSlave.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 also by right-clicking on property element. Connect
Dln.I2cSlave.Port reference output to
Invoke Node to execute available methods. In this example
LoadReply method is used.
After all operations with SPI Slave module is done, close
Dln.Device reference and finally call DlnDisconnect.vi to close connection with Dln Server and
