Create a connection from MATLAB to the specified SoC hardware board using the IP address, username, and password of the board.

hw = socHardwareBoard('Xilinx Zynq ZC706 evaluation kit','hostname','192.168.1.18','username','root','password','root');

Create a data recording session on the SoC hardware board by using thehwobject. The resultingDataRecorderobject represents the data recording session on the SoC hardware board.

dr = soc.recorder(hw)

dr = DataRecorder with properties: HardwareName: 'Xilinx Zynq ZC706 evaluation kit' Sources: {} Recording: false

List the input sources added to the data recording session.

dr.Sources(hw)

ans = 1×0 empty cell array

By default,soc.recorderobjects have no added input sources. To add an input source to the data recording session, first create an input source object by using thesoc.iosourcefunction. For this example, create an User Datagram Protocol (UDP) source object.

udpSrc = soc.iosource(hw,'UDP Receive')

udpSrc = soc.iosource.UDPRead with properties: Main LocalPort: 25000 DataLength: 1 DataType: 'uint8' ReceiveBufferSize: -1 BlockingTime: 0 OutputVarSizeSignal: false SampleTime: 0.1000 HideEventLines: true Show all properties

将这个UDP源对象添加到数据记录ession by using theaddSourceobject function.

addSource(dr,udpSrc,'UDPDataReceived-Port25000')

Verify the result by inspecting theSourcesproperty of thesoc.recorderobject.

dr.Sources

ans = 1×1 cell array {'UDPDataOnPort25000'}

Call the setup function to initialize all hardware peripheral input sources added to the data recording session, and start the data recording process.

setup(dr)

Record data for 60 seconds on the SoC hardware board.

record(dr, 60);

Check the status of the data recording session by using theisRecordingobject function. The recording status when data recording is in progress is1.

recordingStatus = isRecording(dr)

recordingStatus =逻辑1

The recording status when data recording is complete is0.

isRecording(dr)

recordingStatus =罗技cal 0

Save recorded data to a TGZ-compressed file.

save(dr,'UDPDataReceived','UDP Data Testing',{'Recorded On Zynq Board'})

This function saves the recorded data as the fileUDPDataReceived.tgzin your working folder of the host PC. You can read this file by using ansocFileReaderobject in MATLAB or anIO Data Sourceblock in your Simulink model.

Remove the added source from the data recording session by using theremoveSourceobject function.

removeSource(dr,'UDPDataReceived-Port25000')

Verify the result by inspecting theSourcesproperty of thesoc.recorderobject.

ans = 1×0 empty cell array
