基于AVR实现对维根信息码的采集与处理

Realization of the collecting and processing Wiegand code Based on AVR ATmega8515

提出一种基于高性能、低功耗AVR Atmega 8515单片机实现对维根信息码采集的解决方案。本文详细介绍了维根协议(Wiegand26)的格式和规范,给出了软件流程图、核心原程序及硬件接口电路,本方案经过在实际中运行,证明其设计是可靠的。

This paper introduces a solution to Wiegand code information collection which bases on high performance, low power AVR ATmega8515 MCU. It details the pattern and specification of Wiegand protocol （Wiegand26）. It also gives the flowchart of software, the core code and the interface circuit hardware. After the program running in practice, it proves that its design is reliable.
