摘要
在计算机主板BIOS的设计和调试中,通过向LPC总线的80口丢调试信息是行之有效且应用广泛的设计和调试方法之一。本文阐述了利用CPLD芯片编程实现基于LPC总线的调试端口的设计技术。该技术遵循标准的LPC总线传输协议实现调试端口口信息的监听和显示,实现简单方便且容易掌握和理解。
Keyboard＆mouse, based on USB bus interface, as the basic computer peripherals, that have been widely used because of their hot-swappable. This design uses a low-power microcontroller with a USB device interthce, and uses GPIOs of the microcontroller as input and output for keyboard light and keypad scanned array, and mouse data based on PS/2 interface is the input to the microcontroller, and the only USB device interlace is a channel for communication with a host computer, for achieving to control of the host computer with the composite Device with Keyboard＆Mouse. Key words USB-bus interface Composite device with keyboard＆mouse Low-power microcontroller
