+Example description
+===================
+This example provides a description of how to transfer two data buffer from I2C1
+to I2C2 using its both addresses in the same application.
+
+The example consist in two parts:
+1. First step, the I2C1 master transmitter sends the Tx_Buffer1 data buffer to the
+ slave I2C2 which saves the received data in Rx_Buffer1. I2C2 is addressed in
+ this case by its first slave address I2C2_SLAVE1_ADDRESS7 programmed in the
+ I2C2 OAR1 register.
+ The transmitted and received buffers are compared to check that all data
+ have been correctly transferred.
+2. Second step, the I2C2 is now addressed by its second slave address
+ I2C2_SLAVE2_ADDRESS7 programmed in the I2C2 OAR2 register. The Tx_Buffer2
+ contents are transmitted by the master I2C1 to the slave I2C2 which stores
+ them into Rx_Buffer2.
+ A second comparison takes place between the transmitted and received buffers.
+
+The communication clock speed is set to 200KHz.

+stm32f10x_it.c Interrupt handlers

+
+
+Hardware environment
+====================
+This example runs on STMicroelectronics STM3210B-EVAL and STM3210E-EVAL evaluation
+boards and can be easily tailored to any other hardware.
+
+ - 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
+
+Note: The pull-up resitors are already implemented on the STM3210B-EVAL and
+ STM3210E-EVAL evaluation boards.
+
+
+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_gpio.c
+ + stm32f10x_nvic.c
+ + stm32f10x_flash.c
+
+- Link all compiled files and load your image into target memory
+- Run the example
