"基于AT89C51单片机的简易计算器设计与实现"

In the field of electronics, calculators play a crucial role in everyday life and have become an essential tool for many people. The development of calculators has been rapid, with newer models constantly emerging that offer more advanced features and capabilities. To better understand the inner workings of calculators, a simple calculator was designed and developed as part of a course project. This simple calculator is capable of performing basic arithmetic operations such as addition, subtraction, multiplication, and division within a range of 14 digits. It also has the ability to handle negative numbers and display results accurate to two decimal places. The calculator is powered by an AT89C51 microcontroller chip, which serves as the core processing unit. The output is displayed on an LCD1602 industrial character liquid crystal display. The completion of the calculator project involved thorough testing to ensure that all predefined functions were successfully implemented. The design and execution of the calculator were meticulously planned, with attention to detail and a focus on usability. The resulting calculator is not only functional but also user-friendly and has high practical value. In conclusion, the simple calculator project serves as a valuable learning experience in the study of microcontrollers and electronic devices. It demonstrates the application of microcontroller technology in everyday devices and highlights the importance of precision and accuracy in electronic calculations. Overall, the project showcases the potential of microcontrollers in creating practical and useful electronic products like calculators.
