Chapter 17 Shaking Hands with a Digital Partner
© National Instruments Corporation 17-9 LabVIEW Data Acquisition Basics Manual
For the other devices that support digital handshaking, the example would
be the same as above except the
handshaking mode
input would be deleted
from the DIO Config VI and the DIO Start VI would be replaced with the
DIO Buffer Control VI. Also, you do not need the
handshake source
and
clock frequency
inputs for most devices, because of the external
handshaking signal source. Figure 17-8 shows the VI used for all
DAQ devices other than the DIO-32 Series.

Reading Data with the Digital VIs Using Digital Handshaking
Circular-Buffered Examples
Circular-buffered handshaking is similar to simple-buffered handshaking
in that both types of handshaking place data in a buffer; however, a circular
buffer application returns to the beginning of the buffer when it reaches the
end, and fills the same buffer again.
Note
Remember that circular-buffered handshaking works only on the AT-DIO-32F
and DIO-32HS devices.
