INTRODUCTION
Coin operated public mobile phone charger. Yuki is a low cost, multi-functional and "highly intelligent" public coin-operated mobile phone charger The coin-operated mobile phone charger is already successfully installed in hundreds of locations worldwide, providing a unique service to the public and a source of revenue for site providers. The coin-operated mobile charger can be quickly and easily installed in any busines premises.
The charger offers a unique revenue opportunity for a vast range of businesses - from airports to pubs, from universities to health clubs; virtually any location where there is a high footfall, creating a large number of potential users.
The mobile phone market is a billion pound industry, and the launch of new generation mobile phones with cameras and video, means the battery life of todays mobile phone is becoming noticeably shorter. One of the most annoying things that can happen to a mobile phone user is a flat battery, particularly at inconvenient times when access to a standard charger isn't possible. The coin-operated mobile phone
charger are designed to solve this problem.
writing actual code for Microcontroller
After the development of the algorithm and flowchart we have actually translated them in C language for Atmel 89C51 Microcontroller so that it can understand the instructions and run as per our requirement. The instructions are in ANSII C Language.
Compiling the code
The code is implemented on the computer for which we have used Keil pre-installed on PC. The Keil is a Computer Aided Program to simulate the working of Microcontroller in real time without burning the software into actual IC. We simulated and compiled our program for error checking. After removing of several compiling errors the program was converted into machine language i.e. Intel hex format.
Brief Description
The AT89C51 is a low-power, high-performance CMOS 8-bit microcomputer with 4K bytes of Flash programmable and erasable read only memory (PEROM). The device is manufactured using Phillips’s high-density nonvolatile memory technology and is compatible with the industry-standard MCS-51 instruction set and pinout. The on-chip Flash allows the program memory to be reprogrammed in-system or by a conventional nonvolatile memory programmer. By combining a versatile 8-bit CPU with Flash on a monolithic chip, the Phillips AT89C51 is a powerful microcomputer which provides a highly-flexible and cost-effective solution to many embedded control applications.
