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 the slave I2C2. Following the start condition generation, 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. A correct transmission leads to obtaining the following variable values: - Status = 0x01 (the flag SMBDEFAULT has been set) - ReceivedCommand = 0x01 (the Command value has been correctly received) The communication clock speed is set to 200KHz.

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 target memory - Run the example ******************* (C) COPYRIGHT 2008 STMicroelectronics *****END OF FILE******
