Access Measurement Information

This example shows how to open an A2L file and access measurement information.

Open an A2L file:

a2lfile = xcpA2L('XCPSIM.a2l');

Display properties of the A2L object:

a2lfile
A2L with properties:

                 FileName: 'XCPSIM.a2l'
                 FilePath: 'H:\Documents\work\XCPSIM.a2l'
                SlaveName: 'CPP'
        ProtocolLayerInfo: [1x1 struct]
                  DAQInfo: [1x1 struct]
    TransportLayerCANInfo: [1x1 struct]
                   Events: {'Key T'  '10 ms'  '100ms'  '1ms'  'FilterBypassDaq'  'FilterBypassSt'}
             Measurements: {1x38 cell}

View all available measurements:

a2lfile.Measurements

Get information about the BitSlice measurement:

getMeasurementInfo(a2lfile,'Triangle')
