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
  1. #define IIC_SCL_PIN                         GPIO_PIN_6
    

  2. #define IIC_SCL_GPIO_PORT                   GPIOB
    

  3. #define IIC_SCL_GPIO_CLK                    RCU_GPIOB
    


  4. 

  5. #define IIC_SDA_PIN                         GPIO_PIN_7
    

  6. #define IIC_SDA_GPIO_PORT                   GPIOB
    

  7. #define IIC_SDA_GPIO_CLK                    RCU_GPIOB
    

  8.  
    

  9. #define OLED_SCLK_Clr() gpio_bit_reset(IIC_SCL_GPIO_PORT,IIC_SCL_PIN)
    

  10. #define OLED_SCLK_Set() gpio_bit_set(IIC_SCL_GPIO_PORT,IIC_SCL_PIN)
    

  11.  
    

  12. #define OLED_SDIN_Clr() gpio_bit_reset(IIC_SDA_GPIO_PORT,IIC_SDA_PIN)
    

  13. #define OLED_SDIN_Set() gpio_bit_set(IIC_SDA_GPIO_PORT,IIC_SDA_PIN)
    

  14. int iic_init(void)
    

  15. {
    

  16.     rcu_periph_clock_enable(IIC_SCL_GPIO_CLK);
    

  17.     rcu_periph_clock_enable(IIC_SDA_GPIO_CLK);
    

  18.     
    

  19.         /* configure led GPIO port */
    

  20.     gpio_mode_set(IIC_SCL_GPIO_PORT, GPIO_MODE_OUTPUT, GPIO_PUPD_PULLUP,IIC_SCL_PIN);
    

  21.     gpio_output_options_set(IIC_SCL_GPIO_PORT, GPIO_OTYPE_PP, GPIO_OSPEED_50MHZ,IIC_SCL_PIN);
    

  22.         
    

  23.         gpio_mode_set(IIC_SDA_GPIO_PORT, GPIO_MODE_OUTPUT, GPIO_PUPD_PULLUP,IIC_SDA_PIN);
    

  24.     gpio_output_options_set(IIC_SDA_GPIO_PORT, GPIO_OTYPE_OD, GPIO_OSPEED_50MHZ,IIC_SDA_PIN);
    


  25. 

  26.     return 0;
