基于AVR单片机的异步串行信号检测装置

Measure Equipment of Simple Asynchronous Serial Signal Based on AVR Single Micyoco

本文提出了一种简易通用异步串行信号检测装置的设计方法。介绍了AVR系列单片机Atmega128和USB2.0接口芯片的功能特性,并实现异步串行信号检测装置。阐述了通过USB2.0接口控制单片机工作模式的过程。应用单片机内部大容量RAM对接收的高速串行数据进行转存,实现高速接收低速转发回计算机进行检测的目的。

This paper advised a designment of measurement equipment of simple universal asynchronous serial signal. It introduced the array of AVR SCM (Single Chip Micyoco ) Atmega128 and the function characteristics of USB2.0 interface chip, then carried out asynchronous serial signal measurement. In this paper, it also described the process of AVR working modes through USB2.0 to control the interface. Using the larger capacity RAM of SCM interior it storages the received high speed serial data, then achieves the pur...
