DiiVA多功能插座设计与实现

Design and Implementation of DiiVA Wall Plate

为实现HDMI设备接入DiiVA家庭交互网络,采用32位MCU作为主控芯片与DiiVA接口芯片相结合的方式,设计一款DiiVA多功能插座。MCU主要负责驱动DiiVA接口芯片,并实现红外数据采集与发射;DiiVA接口芯片则负责HDMI、以太网、USB及红外信号与DiiVA信号的相互转换与传输功能。该系统由一套嵌入式程序控制设备运行,它是系统的核心,集成了红外驱动、DiiVA芯片驱动以及系统控制逻辑模块。由此可知,DiiVA多功能插座实现红外信号远程传输,HDMI设备接入DiiVA网络,以太网与DiiVA网络融合等功能。

In order to implement the feature which HDMI device can also access the DiiVA interactive home network, a methodology that integrate 32 bit MCU and DiiVA interface chip into the DiiVA wall plate is described. In this way, 32 bit MCU as the master chip control the system activities, it is responsible for driving the DiiVA interface chip, and for infrared data sampling and propagation; DiiVA interface chip is responsible for transmit- ting HDMI, Ethernet, USB signal over DiiVA network. The system operation is under control by a embedded program, it is the core of the system, it consist of the infrared driver, the DiiVA chip driver, the system control logic modules and so on. At this point, the DiiVA wall plate implements the infrared remote transmission, HDMI, Ethernet, USB and DiiVA network integration.
