Open VI

Owning Palette: SPI VIs

Requires: myRIO Toolkit or roboRIO Toolkit

Opens a reference to a serial peripheral interface (SPI) channel. You must open a reference before you use an SPI channel to write data to or read data from an SPI slave device.

	Allow multiple opens? specifies whether to allow opening the specified channel more than once. The default is FALSE. You must set Allow multiple opens? to TRUE if you also use the specified channel in an Express VI.
	Channel Name specifies the name of the SPI channel whose reference you want to open.
	error in describes error conditions that occur before this node runs. This input provides standard error in functionality.
	SPI Ref Out returns the reference to the SPI channel that you specify.
	error out contains error information. This output provides standard error out functionality.
