摘要
在感应式电度表的基础上,结合IC卡与单片机ATmega8设计预付费电度表。电路设计中充分利用单片机ATmega8的硬件资源SPT接口和l^2C接口,使系统的设计更为简单,本文中详细介绍系统的软硬件设计。
The predestine-fee electric kilowaterhour meter was designed based on Induction electric kilowaterhour meter and IC card and singechip ATmega8. The resources of hardware (SPI and I^2C interface) was used full. So system become simple. The designed principle of hardware and software was introduced in the paper.
