Example description
===================
This example provides a description of how to transfer a data buffer from I2C1 to
I2C2 using interrupts.
The communication is a configured on 7bit addressing mode with a clock speed set 
to 200KHz.

After enabling the two I2C peripherals and the two event and buffer interrupts,
the transfer in 7-bit addressing mode starts after the I2C1 start condition is
generated. Each time an event occurs on the master or the slave, it is managed
in the I2C1 or I2C2 interrupt routine, respectively. In this application, I2C1
Tx_Buffer is transmitted from the master (I2C1) to the slave (I2C2) and stored
into I2C2 Rx_Buffer. At the end of the transfer, the PEC is transmitted from
master to slave. It is then saved in the PEC_Value variable. All transmitted and
received buffers are compared to check that all data have been correctly transferred.

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
