ADAC LabVIEW VI 152
ADAC Get DMA Chan
This VI gets the hardware DMA channel of the device. See the AL_SetDmaChan.VI for
the available options.
Device Handle (0) Device Handle is a numeric value that is used to identify the device
subsystem. The default Device Handle is 0.
error in (no error) Error in describes error conditions occurring before this VI executes.
This cluster defaults to no error.
Device Handle out Device Handle out contains the value of Device Handle in.
DMA CHAN DMA Chan is a numeric value that sets the hardware DMA channel of the
device. The available settings are:
0:DISABLED DMA disabled
1:DMA1 DMA channel 1
2:DMA2 DMA channel 2
3:DMA3 DMA channel 3
4:DMA5 DMA channel 5
5:DMA6 DMA channel 6
6:DMA7 DMA channel 7
DMA Chan String DMA Channel String is a string value that represents the hardware
DMA channel currently configured in the LDSD.
error out Error out contains error information. If the error in cluster indicated an error,
the error out cluster contains the same information. Otherwise, error out describes the
error status of this VI.
