Implementation of a Chaotic Oscillator into a Simple Microcontroller

In this work, an experimental implementation of a chaotic oscillator is proposed. Many works have been proposed in order to solve some different interesting problems, such that determining structural damages in materials or for secure communications purpose. However, several approaches are in continuous-time, whereas in many cases, the systems are desired to be in discrete-time mode and in real time. In this work we present the implementation of one chaotic oscillator (Lorenz system) into a simple microcontroller, the implementation consists only of a low cost microcontroller, a few resistors and a simple algorithm. The algorithm could be easily modified to add or substitute the chaotic system.
