1、用GD32模拟IIC时序，第一步是端口的定义和配置可以很方便的移植IIC程序，核心代码如下：
复制
#define IIC_SCL_PIN                         GPIO_PIN_6

#define IIC_SCL_GPIO_PORT                   GPIOB

#define IIC_SCL_GPIO_CLK                    RCU_GPIOB



#define IIC_SDA_PIN                         GPIO_PIN_7

#define IIC_SDA_GPIO_PORT                   GPIOB

#define IIC_SDA_GPIO_CLK                    RCU_GPIOB

 

#define OLED_SCLK_Clr() gpio_bit_reset(IIC_SCL_GPIO_PORT,IIC_SCL_PIN)

#define OLED_SCLK_Set() gpio_bit_set(IIC_SCL_GPIO_PORT,IIC_SCL_PIN)

 

#define OLED_SDIN_Clr() gpio_bit_reset(IIC_SDA_GPIO_PORT,IIC_SDA_PIN)

#define OLED_SDIN_Set() gpio_bit_set(IIC_SDA_GPIO_PORT,IIC_SDA_PIN)

int iic_init(void)

{

    rcu_periph_clock_enable(IIC_SCL_GPIO_CLK);

    rcu_periph_clock_enable(IIC_SDA_GPIO_CLK);

    

        /* configure led GPIO port */

    gpio_mode_set(IIC_SCL_GPIO_PORT, GPIO_MODE_OUTPUT, GPIO_PUPD_PULLUP,IIC_SCL_PIN);

    gpio_output_options_set(IIC_SCL_GPIO_PORT, GPIO_OTYPE_PP, GPIO_OSPEED_50MHZ,IIC_SCL_PIN);

        

        gpio_mode_set(IIC_SDA_GPIO_PORT, GPIO_MODE_OUTPUT, GPIO_PUPD_PULLUP,IIC_SDA_PIN);

    gpio_output_options_set(IIC_SDA_GPIO_PORT, GPIO_OTYPE_OD, GPIO_OSPEED_50MHZ,IIC_SDA_PIN);



    return 0;

}

3.写调用IIC函数控制oled屏函数：

5.主程序调用oled初始化，显示函数，实现显示：
复制
int main(void)

{

//    gd_led_config();

        iic_init();

    systick_config();



//    unsigned int t=1;

        OLED_Init();            //初始化OLED  

        OLED_Clear();         //清屏函数

                

                //这个函数显示中文

                OLED_ShowCHinese(18,0,0);//兆        //第一个形参是列，第二个是行，第三个是显示哪个中文，这里一个字占16宽

                OLED_ShowCHinese(36,0,1);//易

                OLED_ShowCHinese(54,0,2);//科

                OLED_ShowCHinese(72,0,3);//技

                

                //这个函数显示字符

                OLED_ShowString(6,3,"GD32F310G-START",16);//第一个形参表示第六行，第二个形参表示排，第三个表示写入的字符，第四个表示字体大小



 while(1) 

        {            }      

}
