Pic Microcontroller-based Smart Phone Charger

One mobile telephone cell charger is necessarily to a mobile telephone user. The intelligent charger based on microcontroller can charge for all mobile telephone cell. This paper introduces the condition of mobile telephone cell charger. On the basis of analysis to the condition,this paper build a intelligent charger for all mobile telephone cell.To meet the requirement of all mobile telephone cell, the author selects high performance hardware and designs stable and reliable software. The hardware of the system is introduced detailedly including data acquisition circuit, control circuit, power supply, interface between the system and the people,microcontroller. 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, stability, 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.
