文档介绍：摘要
在学****单片机的过程中,通过做了一系列的实验,从而比较容易地领会了单片机哪些枯燥、难懂的专业术语,而且此次设计的单片机开发板弥补了市场上常见的单片机实验板的一些不足,有针对性地面向最终的实用控制功能,使整个开发板分解成若干个小模块,并且每个模块引出了一些引脚,这样使用者就可以根据自己的需要连接自己的电路,增加了开发板的灵活性。本单片机开发板包括:单片机最小系统、A/D电路功能模块、D/A电路功能模块、串口、2位数码管、驱动步进电机电路、4×4键盘、液显(1602)显示功能、温度测量功能、喇叭等功能模块。通过以上的功能模块可以完成基本的单片机学****实验。因此,我利用单片机控制ds18b20芯片实现了温度计的开发实验。

Abstract
In the study process of MCU, By doing a series of experiments,So it can easier to understand which of the microcontroller’s boring and hard to understand terminology。And the design of microcontroller development board made up mon market’s microcontroller development board’s a number of inadequacies, targeted for the end of the practical control, So that the whole development board broken down into several small modules, And each module raises a number of pins, So that users can connect to their own needs according to the you can use the MCU development board e more MCU development board include: Minimum System of MCU,A / D circuit functional modules, D / A circuit functional modules, serial, 2-bit digital led control, drive a stepper motor circuit, 4 × 4 keyboard, LCD(1602) display, temperature measurement function modules, Speakers function modules and so on. Through the above function modules plete the basic of MCU’s experiment.
