Quick Porting Guide

Add the following codes for your platform and you are pretty much ready to go.

sensor_driver_test.c: main program

• Add the time delay function

  #define DELAY_MS(ms)	//.....     /* Add your time delay function here */
  

• Add HW initialization

  /* Add your HW initialization code here
  ...
  ...
  ...
  ...
  */
  

bus_support.c

• Add I2C read/write function pointer to your I2C functions

   pbus->bus_read = I2C_read_bytes;    /* Put your I2C read function pointer here */
   pbus->bus_write = I2C_write_bytes;  /* Put your I2C write function pointer here */
  

  Your I2C read/write functions should implement the following interface:

  //******************************************************************************
  //
  //! @brief Read multiple bytes from I2C slave with address devAddr
  //!
  //! @param devAddr 7-bit device slave address
  //! @param regAddr start register address
  //! @param dataBuf data byte array to store the reading
  //! @param len number of data to be read
  //
  //! @return number of bytes read
  //
  //******************************************************************************
  char I2C_read_bytes(unsigned char devAddr, 
  					unsigned char regAddr, 
  					unsigned char* dataBuf, 
  					unsigned char len)
   {
    /* ..... */
   }
  
  //******************************************************************************
  //
  //! @brief Write multiple bytes to I2C slave with address devAddr
  //!
  //! @param devAddr 7-bit device slave address
  //! @param regAddr register address
  //! @param dataBuf data bytes array buffer with datas to write
  //! @param len number of bytes to write
  //!
  //! @param return number of byte written
  //
  //******************************************************************************
  char I2C_write_bytes(unsigned char devAddr,
                       unsigned char regAddr,
  					 unsigned char* dataBuf,
  					 unsigned char len)
  
  {
   /* ..... */
  }
