基于ZigBee RF4CE的LED遥控系统的设计

Remote Control of LEDs based on ZigBee RF4CE

ZigBee RF4CE协议是ZigBee联盟与RF4CE联合会于2009年制定的新一代家电遥控标准,具有更远的传播距离、更好的抗干扰能力,并允许电器设备之间进行双向交互。提出了一种基于RF4CE标准的LED系统的遥控系统设计。该系统应用飞思卡尔MC13213作为无线通信控制器通过lin总线控制LED系统的红绿蓝三色。调光控制使用freescale的MM908E625和3轴加速传感器MMA7260QT。

ZigBee RF4CE, created jointly by the ZigBee Alliance and RF4CE Consortium, is a standardized specification for RF - based remote controls. It provides a multi - vendor interoperable remote control solution for consumer electronics featuring a simple, robust and low - cost communication network realizing two - way wireless connectivity. This paper de- scribes a reference design of a high brightness LED control solution using the freescalc MC13213 microcontroller, which u- ses a microcontroller （MCU） to control the red/green/blue （RGB） color LEDs and increases system flexibility by lin bus. A SCI to LIN level shifter is used to make the SCI levels with LIN levels on the MM908E625 and MMA7260QT.
