Hardware Description

2.1 Introduction

The system consists of a MCU control board and a LED driving board. The MCU control board, DEMO9S08AW60LED, is one of the demonstration boards for the Freescale MC9S08AW60. This board allows easier developmet of code for LED control applications, architectural/entertainment lighting or LCD backlighting. The on-board serial interface allows you to control and monitor the system status via the RS232 serial port connection. The separated LED light-box with driving circuitries is also available as a whole demo kit to demonstrate how to do the color mixing and see the visual effects on changing different type of parameter settings.
