@par Example Description 

This example provides a description of how to use the I2C to communicate with 
an STLM75 (or a compatible device) I2C temperature sensor is mounted on the 
STM320518-EVAL board and used to get instantaneous external temperature
(-55°C to +125°C).
 
Thanks to STM32 I2C SMBus feature, we can easily monitor the temperature 
variations. This is managed by the SMBus Alert which is generating a dedicated 
interrupt informing the system that the temperature is out of the selected 
ranges.

The user can configure the TOS and THYS thanks to a dedicated define values in 
the code.

By default the STM320518-EVAL demo are setting them to (see main.c file):
  
   #define TEMPERATURE_THYS 31
   #define TEMPERATURE_TOS 32

@par Hardware and Software environment

  - This example runs on STM32F0xx Devices.
  
  - This example has been tested with STMicroelectronics STM320518-EVAL (STM32F0xx)
    evaluation board and can be easily tailored to any other supported device 
    and development board. 

  - STM320518-EVAL Set-up
    - STLM75 I2C temperature sensor is already available on this board.


@par How to use it ? 

In order to make the program work, you must do the following :
 - Copy all source files from this example folder to the template folder under
   Project\STM32F0xx_StdPeriph_Templates
 - Open your preferred toolchain 
 - Add the following file the project source list
     - Utilities/STM32_EVAL/STM320518_EVAL/stm320518_eval_i2c_tsensor.c
 - Rebuild all files and load your image into target memory
 - Run the example
