"Flatten To JSON" element

Flatten To JSON

LabVIEW RT block diagram snippet: Read the onboard accelerometer and pushbutton, convert to JSON string, and write to TCP channel

TCP client-server
RT code PC code

Create a server on the Academic RIO Device that listens for TCP/IP network connection requests from a client running on the PC host, accepts client information including the desired state of the four onboard LEDs, sets the LEDs accordingly, and returns the state of the onboard 3-axis accelerometer and pushbutton.

LabVIEW RT block diagram snippet: Read the onboard accelerometer and pushbutton, convert to JSON string, and write to UDP channel

UDP client-server
RT code PC code

Create a server on the Academic RIO Device that listens for UDP datagram messages from a client running on the PC host, accepts client information including the desired state of the four onboard LEDs, sets the LEDs accordingly, and returns the state of the onboard 3-axis accelerometer and pushbutton.

LabVIEW RT block diagram snippet: Control onboard LEDs from web form data, return system date/time

Host a Web service
RT code

Host a web service on the Academic RIO Device to serve the states of onboard sensors (pushbutton and accelerometer) and system information (date, time, host name, and IP address), and to control the onboard LEDs based on a user-selected LED hex code.
