AVR单片机性能优越，有着广阔的市场前景，本设计主要研究AVR单片机的各部分功能，了解AVR单片机及其外围芯片连接，做出接口软件。

本设计将AVR单片机各部分功能融合起来，采用Atmega16L作为系统的核心，以12864为液晶显示，以RS232转换PC到单片机的电平，采用Atmega16L本身的A/D等等，出于价格和研究实用性方面的考虑本系统采用万用板制作。

经实践证明，该系统可以对AVR单片机的各部分功能进行实验研究，达到了对AVR单片机系统设计的要求，性能稳定，结构合理，适合在教学和实际应用中推广。

-AVR microcontroller superior performance, has broad market prospects, the main research design AVR microcontroller function of each, about AVR microcontrollers and peripheral chips to connect, to make interface software. The AVR microcontroller design will integrate the various parts function, using Atmega16L as the core of the system, to 12864 for the liquid crystal display to RS232 converter PC to MCU level, using Atmega16L own A/D, etc., for the price and of practical of considerations of the system used by 10,000 board production. The practice shows that the system can AVR microcontroller function of each experimental study, achieved the AVR microcontroller system design requirements, performance and stability, reasonable structure, suitable for practical application in the teaching and promotion.
