Write Handshake (Clock-Driven Logic)

Last Modified: August 28, 2017

Writes an element of data to a handshake item.

If the ready for input terminal returns False during a given cycle, this node discards any data that other nodes send to this node during the following cycle. This node discards this data even if input valid is True during the following cycle.

reference in

Reference to a handshake item. You can wire a handshake control, handshake constant, or the reference out terminal of another Handshake node to reference in.

datatype_icon

data

The data to transfer using the handshake item. The data type of data is the data type you wire to the Create Handshake node that creates the handshake item.

datatype_icon

input valid

A Boolean that determines whether the next data point has arrived for processing. Wire the output valid output of an upstream node to this input to transfer data from the upstream node to this node.

True The next data point has arrived for processing.
False The next data point has not arrived for processing.
datatype_icon

reference out

The same handshake reference wired into this node.

datatype_icon

ready for input

A Boolean that indicates whether the previous write operation is complete and the node is ready to accept data. Use a Feedback Node to wire this output to the ready for output input of an upstream node.

True The previous write operation is complete and the node is ready to accept new input data.
False The previous write operation is not complete and the node discards any data that other nodes send to this node during the following cycle.

Where This Node Can Run:

Desktop OS: none

FPGA: All devices

Web Server: Not supported in VIs that run in a web application
