Blinking outputs of the Raspberry Pi

A very basic project which demonstrates access to GPIO pins of the Raspberry Pi platform.

Prerequisites

• REXYGEN Runtime Core and RPiDrv module must be installed and running on the Raspberry Pi
• The wiring must comply with the attached schematics.

Timing of the project

The algorithm runs each 20 milliseconds (0.02 s). See the EXEC function block,
tick x ntick0 = 0.02 x 1 = 0.02 s

Running the example

• The *exec.mdl file is the project main file
• Open it with REXYGEN Studio, compile and download it to the target device

User interface (HMI)

The example is accompanied by a HTML5-based user interface built on the WebBuDi framework (Web Buttons and Displays).
