基于 AT89C51 单片机的数字音乐盒设计 Design of digital music box based on AT89C51 MCUI ABSTRACTIn this paper, the digital music box design of AT89C51 single-chip microcomputer is taken as the design object. In order to reduce the design cost as much as possible, the DS18B20 sensor is selected as the main part of the digital music box design hardware. On the basis of meeting the requirements of temperature accuracy range, this paper designs the overall scheme of the design of digital music box based on AT89C51 single chip microcomputer. At the same time, it is necessary to ensure that the design speed regulation is accurate and the error is as small as possible. All the modules needed to be applied to the digital music box are selected and analyzed one by one. The design of digital music box based on AT89C51 single chip microcomputer mainly includes the following points: Consult the literature, consult the domestic and foreign data about the design of digital music box based on AT89C51 single chip microcomputer, according to the literature, explore the background and current situation of the design of digital music box based on AT89C51 single chip microcomputer at home and abroad, on this basis, establish the research framework of digital music box based on AT89C51 single chip microcomputer. Through the study of how to choose the model of each component, the overall scheme of digital music box based on AT89C51 is designed, and the design scheme is compared with other models. On the basis of the design of digital music box based on AT89C51 single chip microcomputer, the internal details are designed, including the design of hardware system, power circuit, storage circuit and display circuit....
