1.8寸显示屏和stm32怎么接

目录

一、所选模块

液晶模块选择（淘宝上均有售卖）

模块引脚

二、嵌入式单片机型号

三、接线表设计

四、开发环境版本说明

五、标准库实现

六、HAL库实现

七、完整工程（内含标准库和HAL库源码）

代码链接

一、所选模块

液晶模块选择（淘宝上均有售卖）

1.8寸液晶屏 LCD SPI串口显示屏模块 TFT彩屏

模块引脚

二、嵌入式单片机型号

本博客选用的单片机型号：STM32F103C8T6

该款单片机应用就多，相对性价比较高。

三、接线表设计

由于液晶模块采用的是SPI通信，但这里均使用模拟SPI的方式进行通信，实现液晶显示（后面博客会使用STM32自带的SPI功能实现数据传输）。

TFT真彩屏 液晶模块STM32F103C8T6
GND电源地
VCC接5V或3.3v电源
SCLPA6（SCL）
SDAPA7（SDA）
RESPB0
DCPB1
CSPB10 
BLPB11

因为液晶模块主要用于显示功能，而且是模拟SPI通信，这里的所以的IO口均设置成推挽输出模式。引脚接线是依据需要修改的，但需要大家修改完全，不然不能成功。

四、开发环境版本说明

标准库的开发环境：

HAL库开发环境：

STMCUBEMX、KEIL5

五、标准库实现

由于工程文件较多，只给出部分核心代码，供大家参考，博文最后会有全套代码给大家。

六、HAL库实现

CubeMX配置引脚为output，然后修改别名，如下：

时钟配置为32MHz，其它其实也可以，无所谓的。

  2. {

  9.   /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  10.   HAL_Init();
  11.  
  12.   /* USER CODE BEGIN Init */
  13.  
  14.   /* USER CODE END Init */
  15.

  17.   SystemClock_Config();
  18.  
  19.   /* USER CODE BEGIN SysInit */
  20.  
  21.   /* USER CODE END SysInit */
  22.

  26. 	Lcd_Init();
  27. 	HAL_GPIO_WritePin(GPIOB, BL_Pin, GPIO_PIN_SET);//通过IO控制背光亮		
  28.   /* USER CODE END 2 */
  29.  
  30.   /* Infinite loop */
  31.   /* USER CODE BEGIN WHILE */
  32.   while (1)
  33.   {
  34.     /* USER CODE END WHILE */
  35.  
  36.     /* USER CODE BEGIN 3 */
  37. 		QDTFT_Test_Demo();
  38.   }
