Example description
===================
This example provides a description of how to send an ARP command from I2C1 to I2C2
in SMBus mode.

After configuring the I2C1 and I2C2 as SMBus Host and Device, respectively, both I2Cs are
enabled. The PEC calculation is enabled for both I2Cs. The ARP capability is enabled for
slave I2C2. After the start condition, the master (I2C1) sends the SMBus default header and
I2C2 responds by setting its SMBDEFAULT flag. The master (I2C1) then issues the Prepare
to ARP command to the slave (I2C2). PEC transfer is then enabled for both I2Cs, and the
PEC value received on I2C2 is stored into the PEC_Value variable.

The communication clock speed is set to 200KHz.


Directory contents
==================
stm32f10x_conf.h  Library Configuration file
stm32f10x_it.c    Interrupt handlers
stm32f10x_it.h    Interrupt handlers header file
main.c            Main program


Hardware environment
====================
 - Connect I2C1 SCL pin (PB.06) to I2C2 SCL pin (PB.10)
 - Connect I2C1 SDA pin (PB.07) to I2C2 SDA pin	(PB.11)
 - Check that a pull-up resistor is connected on one I2C SDA pin
 - Check that a pull-up resistor is connected on one I2C SCL pin


How to use it
=============
In order to make the program work, you must do the following :
- Create a project and setup all your toolchain's start-up files
- Compile the directory content files and required Library files :
  + stm32f10x_lib.c
  + stm32f10x_i2c.c
  + stm32f10x_rcc.c
  + stm32f10x_nvic.c
  + stm32f10x_gpio.c
  + stm32f10x_flash.c
    
- Link all compiled files and load your image into either RAM or FLASH
- Run the example
