# 实现功能：软件I2C

* 使用说明：
  1. 创建一个SW_I2C_HOOKS类型的实例并绑定10个所需的接口函数
  2. 调用sw_i2c_regist_init注册并初始化
  3. 调用sw_i2c_read_bytes和sw_i2c_write_bytes函数进行I2C读写操作

* 示例代码：
  ```c
  #define SLALVE_ADDR_7BIT 0x38
  int main(void)
  {
      unsigned char tx_buf[2] = {0x01, 0x02}, rx_buf[2] = {0};
  
      SW_I2C_HOOKS sw_i2c = {0};
      sw_i2c.GPIO_INIT = myGPIO_INIT;
      sw_i2c.SDA_OUT = mySDA_OUT;
      sw_i2c.SDA_IN = mySDA_IN;
      sw_i2c.READ_SDA = myREAD_SDA;
      sw_i2c.SDA_H = mySDA_H;
      sw_i2c.SDA_L = mySDA_L;
      sw_i2c.SCL_H = mySCL_H;
      sw_i2c.SCL_L = mySCL_L;
      sw_i2c.DELAY_5US = myDELAY_5US;
      sw_i2c.DELAY_2US = myDELAY_2US;
      sw_i2c_regist_init(&sw_i2c);
  
      sw_i2c_write_bytes(SLALVE_ADDR_7BIT, tx_buf, 2);
      /* 注意：很多I2C器件写操作完成后需要等待一定的时间才能读到数据 */
      sw_i2c_read_bytes(SLALVE_ADDR_7BIT, rx_buf, 2);
  
      return 0;
  }
  ```
