STM32使用DHT11传感器读取温湿度，显示在LCD屏上

黑心小红帽 2024-03-20 原文

文章目录

1. 温湿度传感器 DHT11/12

传感器中有一个高性能的8位单片机，会采集并完成数据转换。

1.1 DHT1x应用电路图

1.2 温湿度模块引脚

1.3 连接到STM32上的引脚

1.4 STM32CubeMX属性配置

这里给PA8重新给了名字，叫DHT，代码中也做相应修改。

1.5 调用函数

dht.c放在最后，主函数中需要开启tim6定时器，调用dht_read()函数即可实现温湿度的读取。

传输的数据格式（40位）：8bit湿度整数数据 + 8bit湿度小数数据 + 8bit温度证书数据 + 8bit湿度小数数据 + 8bit校验和。
8位校验和 = 8bit湿度整数数据+8bit湿度小数数据+8bi温度整数数据+8bit温度小数数据 所得结果的末8位。

2. I2C和SPI的工作原理

I2C和SPI都是芯片和芯片之间通信总线，都有时钟线，都是同步的。

2.1 I2C

I2C用2根双向信号线（时钟线SCL，数据线SDA）来传输数据。
半双工的通信方式，同步

1对n的模式，一个主机，n个从机，每一个从机都有一个7位的地址，主机通过地址找到从机。

传输开始：时钟线高电平，数据线由高变低

传输结束：时钟线高电平，数据线由低变高

2.2 SPI

串行外围设备接口，全双工的通信总线，高速，同步。

接口有四根线：

  • 串行时钟线SCK

  • 主机输入/从机输出数据线MISO

  • 主机输出/从机输入数据线MOSI

  • 低电平有效的从机选择线SS ，也叫片选线(有的SPI接口芯片带有中断信号线INT或INT、有的SPI接口芯片没有主机输出/从机输入数据线MOSI)

片选线拉低表示主机选中某个从机。

SPI的工作模式有两种：主模式、从模式，无论那种模式，都支持3Mbit/s的速率

2.3 UART、I2C、SPI比较

UART：3条线（接收数据线RXD，发送数据线TXD，地线GND），串行，半双工，异步
I2C：2条线（时钟线SCL，数据线SDA），半双工，同步
SPI：4条线（串行时钟线SCK，主发从收MOSI，主收从发MISO，片选线SS），全双工，同步

3. 驱动LCD屏

3.1 STM32控制LCD方式

3.2 LCD屏引脚

3.3 连接到STM32上对应的引脚

3.4 STM32CubeMX中设置对应引脚模式

3.5 设置SPI属性

3.6 调用函数

显示在LCD屏上的字符是需要通过文字取模软件转换成16进制的，控制LCD的部分代码在最后。
主函数中需要对LCD屏进行初始化、设置显示区域、清屏。

函数用法举例说明：
lcd_drawcharWen(0, 15, (uint16_t)0x00FF00, (uint16_t)0x000000);
函数作用：在LCD上显示“温”字，温字对应的16进制已经通过取模软件保存在了.c文件的最后，直接调用即可。
参数1：横坐标，从左向右
参数2：纵坐标，从上到下
参数3：前景色
参数4：背景色
