前言

不管哪款LCD，都是同理的，我这款LCD是用的IIC通信。 然后本工程使用普通IO口模拟IIC时序进行通信

一、拿到一款LCD首先确认通信方式，然后确认通信接口

二、然后就是确认控制指令，(指令太多放不完，我就放一部分）

三、LCD的外围电路设计

四、新建工程

五、打开CubeMX

六、时钟使用外部晶振

七、配置下载口

八、打开串口一，调试用

九、配置时钟线，时钟频率拉满

十、选择工具链

十一、生成.c和.h文件

十二、生成代码

十三、主函数中这么写

/** @Description:* @Author: mzh* @Date: 2023-07-31 21:57:47* @LastEditors: mzh* @LastEditTime: 2023-07-31 22:01:58*/

#include "system_deal.h"int main(void)
{SystemStartInit();return RT_EOK;
}

十四、在applications文件下新建system_deal文件夹，再在system_deal文件下新建system_deal.c和system_deal.h文件

十五、继续在system_deal文件夹下新建system_config.h文件

十六、包含头文件

十七、在system_deal.c中这么写

#endif}
}/*********************************************************************************************************** Function name:       SystemTaskInit** Descriptions:        System Task Init** input parameters:    NONE** output parameters:   NONE** Returned value:      NONE*********************************************************************************************************/

void SystemStartInit(void)
{SystemTaskInit();
}

十八、在system_deal.h中这么写

/** Copyright (c) 2006-2021, RT-Thread Development Team** SPDX-License-Identifier: Apache-2.0** Change Logs:* Date           Author       Notes* 2025-03-13     Administrator       the first version*/

#define SYS_THREAD_PRO 15
#define SYS_THREAD_TICK 10extern void SystemStartInit(void);#endif /* APPLICATIONS_SYSTEM_DEAL_SYSTEM_DEAL_H_ */

十九、system_config.h中这么写

/** Copyright (c) 2006-2021, RT-Thread Development Team** SPDX-License-Identifier: Apache-2.0** Change Logs:* Date           Author       Notes* 2025-03-13     Administrator       the first version*/

#define APPLICATIONS_SYSTEM_DEAL_SYSTEM_CONFIG_H_/* screen config */
#define SCREEN_CONTROL_ENABLE 1#endif /* APPLICATIONS_SYSTEM_DEAL_SYSTEM_CONFIG_H_ */

二十、在applications文件夹下新建screen_deal文件夹，再在screen_deal文件夹下新建lcd_font.c、lcd_font.c、screen_deal.c、screen_deal.h文件夹。

二十一、在lcd_font.c中这么写

/** Copyright (c) 2006-2021, RT-Thread Development Team** SPDX-License-Identifier: Apache-2.0** Change Logs:* Date           Author       Notes* 2025-03-13     Administrator       the first version*/#include "lcd_font.h"

二十五、包含头文件

二十六、编译通过，有一些警告是有关变量类型的，不用在意

二十七、在这个屏幕线程里改这里就能显示出文字

二十八、下载程序后就能在屏幕上显示出字了

二十九、这里的3表示第3行，50表示第50列

三十、这个是LCD的初始化，具体指令的含义需要对照指令表查看

三十一、这里是与LCD通信的IO口，具体可以根据实际使用情况进行修改
