SPI, or Serial Peripheral Interface, is a synchronous serial data link standard that operates in full duplex mode. It is commonly used in the test and measurement field. Typical uses include communicating with micro controllers, EEPROMs, A2D devices, embedded controllers, etc. Using Instrument Control Toolbox™ SPI support, you can open connections with individual chips and read and write over the connections.
Create the interface object using the
and use the
for communication. To use the SPI interface, you must have a Total
Phase Aardvark host adaptor or an NI-845x adaptor board installed.
See Configuring SPI Communication for details.
