有关AVR单片机的bootloader，外国人写的，很实用，内容详细

本设计主要由数字信号发生器和逻辑分析仪组成，其中数字信号发生器运用了89C51单片机系统，可以重复输出8路循环逻辑移位序列，逻辑分析仪用了89C55单片机系统，可以实现8路信号的采集和显示(时间域和空间域)，3级触发字可调，有多种触发功能，可显示时标线,使逻辑分析仪能从大量的数据流中获得有分析意义的数据。-primarily by the design of digital signal generator and logic analyzer, composed of digital signal generator used 89C51 systems, which can output eight repeat cycle shift logic sequence, logic analyzer with the 89C55 microcontroller system, can achieve a 8-way signal acquisition and display (time Victoria and space domain), three adjustable trigger word, a number of trigger functions, can show that the time scale, so the logic analyzer from the large amounts of data flow has been analyzing the meaning of the data.
