CODESYS Example: Knight Rider

This tutorial explains how to create a Knight Rider effect on the LEDs of a RevPi Compact. The digital output LEDs flash sequentially from left to right and back, replicating the iconic light effect.

Prerequisites​

Hardware​

✓ RevPi Compact

For detailed instructions about how to set up your system, see Getting Started.

Software​

✓ CODESYS Development System is installed on your PC

To ensure a compatible system with suitable software, see CODESYS System Requirements.

Overview​

The Knight Rider effect is achieved by:

▷ Configure AI Channel 1 on the RevPi Compact for the 0–10 V range in the Parameters tab.

▷ Use these two tasks:

  • POU_AdjustSpeed: Sets the time interval for the LED sequence based on the analog input value (AI_CH1).

  • POU_KnightRider: Implements the LED shifting effect on the digital outputs, creating the desired left-to-right and right-to-left pattern.
