本次使用的是1.8寸的TFT,以前比较喜欢用0.96寸的OLED,使用OLED的话,显示数字、汉字这些基本功能可以满足了,但是OLED只有单色,在某些场合用着还是不够。正好手上有一个之前9.9买的TFT,在这里使用模拟iic的方式将屏幕点亮。

硬件设计:
使用的是模拟IIC进行通信,使用的引脚可以随意选择,如下所示:

程序设计:
添加LCD文件库

添加头文件路径

初始化I/O口
 CKCU_PeripClockConfig_TypeDef GPIOlock = {{ 0 }};
    GPIOlock.Bit.AFIO = 1;
        GPIOlock.Bit.PC = 1; //使能PC
        GPIOlock.Bit.PA = 1; //使能PC
        CKCU_PeripClockConfig(GPIOlock, ENABLE); //使能时钟
   
       
    AFIO_GPxConfig(GPIO_PA, AFIO_PIN_5|AFIO_PIN_6, AFIO_FUN_GPIO);
        AFIO_GPxConfig(GPIO_PA, AFIO_PIN_0|AFIO_PIN_1|AFIO_PIN_2|AFIO_PIN_3, AFIO_FUN_GPIO);
       
        GPIO_PullResistorConfig(HT_GPIOA, GPIO_PIN_5|GPIO_PIN_6, GPIO_PR_DOWN);
        GPIO_PullResistorConfig(HT_GPIOA, GPIO_PIN_0|GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3, GPIO_PR_DOWN);
       
        GPIO_DirectionConfig(HT_GPIOA, GPIO_PIN_5|GPIO_PIN_6, GPIO_DIR_OUT);
    GPIO_DirectionConfig(HT_GPIOA, GPIO_PIN_0|GPIO_PIN_1|GPIO_PIN_2|GPIO_PIN_3, GPIO_DIR_OUT);
使用宏定义的方式进行语句的使用,也方便移植到其他MCU 上。
