1 Design Overview

The design demonstrates the basic functionality of the PolarFire SoC Video Kit, the PolarFire SoC ICICLE Kit, the Stepper Motor, and their communication with each other over the OPC UA protocol. OPC Unified Architecture (OPC UA) is a machine-to-machine communication protocol used for OPC UA Industrial Edge demo.

The demo can be run with any of the following scenarios.

  • To control Video Kit and ICICLE Kit individually from UAExpert OPC UA client.
  • To control Video Kit through ICICLE Kit – OPC UA client.

Scenario 1

In this scenario, OPC UA Client UAExpert acts as the main controller, which controls the PolarFire SoC Video Kit and the Stepper Motor on the ICICLE Kit. Control signals from UAExpert are sent over the OPC UA channel to the PolarFire SoC Video Kit for video streaming and to stepper motor to start or stop the motor in clockwise or anti-clockwise direction.

Scenario 2

In this scenario, OPC UA Client UAExpert communicates with the Video Kit through the ICICLE Kit. The objective here is to demonstrate the ICICLE Kit’s capability to act as an OPC UA Client. Control signals from the UAExpert are sent over the OPC UA channel to the ICICLE Kit, which in turn is communicated to the PolarFire SoC Video Kit for video streaming.
