摘要
本課題充分利用PIC單片機(jī)的強(qiáng)大功能，進(jìn)行了大量的軟件設(shè)計(jì)，用軟件完成了絕大部分任務(wù):輔以簡單的外圍電路，即實(shí)現(xiàn)了對目前市場上所售的所有手機(jī)進(jìn)行充電，且便于集中管理的功能，重點(diǎn)闡述了系統(tǒng)的軟件設(shè)計(jì)，首先對控制軟件進(jìn)行需求分析，總體目標(biāo)是實(shí)現(xiàn)系統(tǒng)的可靠性、穩(wěn)定性、安全性和經(jīng)濟(jì)性。據(jù)此目標(biāo)，用軟件工程的方法設(shè)計(jì)了系統(tǒng)
的總體框架。以匯編語言為工具，采用面向?qū)ο蟮脑砗图夹g(shù)，進(jìn)行了詳細(xì)設(shè)計(jì)和編碼實(shí)現(xiàn)。

ABSTRACT
Microcontroller,the core of the system, is introduced more detaildely.The software design is mainly
explained. Requirement of the software system have been analyzed firstly. The general aim of the software system is to realize reliability,stabilit.y,safety and ecnomization.Then the author designs the whole framework of the system with the thinking of software engineering. At last, the author makes full use of assemble language according to the object-oriented programming principles and technologies
to implement, the detailed design and coding.
Keywords:mobile telephone cell charger intelligent
based on PIC16F877 40-Pin Flash-Based 8-Bit Microcontroller
