1. 实验准备

  • 硬件方面：
    • 了解 STM32 单片机的基本原理和使用方法，本实验可选用常见的 STM32F103 系列。
    • 熟悉 DS18B20 温度传感器的工作原理和通信协议（单总线协议）。
    • 数码管可选用共阴极或共阳极数码管，用于显示温度值。
  • 软件方面：
    • 安装 Keil MDK 开发环境，用于编写和编译 STM32 的程序代码。
    • 安装 Proteus 仿真软件，用于搭建电路并进行仿真。

2. Proteus 电路搭建

  1. 打开 Proteus 软件：新建一个工程，在元件库中搜索并添加以下元件：
    • STM32F103R6：作为主控芯片。
    • DS18B20：温度传感器。
    • 7SEG-MPX4-CC：4 位共阴极数码管。
    • 电阻、电容等辅助元件。
  2. 连接电路：
    • DS18B20 连接：将 DS18B20 的 VDD 引脚连接到 3.3V 电源，GND 引脚接地，DQ 引脚连接到 STM32 的一个 GPIO 引脚（例如 PA0）。
    • 数码管连接：将数码管的段选引脚（a - g、dp）连接到 STM32 的一组 GPIO 引脚（例如 PB0 - PB7），位选引脚（COM1 - COM4）连接到另一组 GPIO 引脚（例如 PC0 - PC3）。
    • 电源和地：将 STM32 的 VDD 和 VSS 引脚分别连接到 3.3V 电源和地。

3. Keil MDK 代码编写

以下是一个

    简单的示例代码，用于读取 DS18B20 的温度数据并显示在数码管上：

    4. 代码编译

    4. 代码编译和仿真

    编译代码：在 Keil MDK 中，将上述代码保存为 .c 文件，进行编译，确保代码没有错误。

    1. 生成 hex 文件：在 Keil MDK 的项目选项中，配置生成 .hex 文件。
    2. 加载 hex 文件：在 Proteus 中，双击 STM32 芯片，在弹出的对话框中选择生成的 .hex 文件。
    3. 开始仿真：点击 Proteus 中的运行按钮，开始仿真。此时，数码管应该会显示 DS18B20 读取到的温度值。

    5. 注意事项
