+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.h    Interrupt handlers header file

+

+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
