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 20KHz. @par Directory contents - I2C/SMBus/stm32f10x_conf.h Library Configuration file - I2C/SMBus/stm32f10x_it.c Interrupt handlers - I2C/SMBus/stm32f10x_it.h Interrupt handlers header file - I2C/SMBus/main.c Main program @par Hardware and Software environment - This example runs on STM32F10x High-Density, STM32F10x Medium-Density and STM32F10x Low-Density Devices. - This example has been tested with STMicroelectronics STM3210E-EVAL (STM32F10x High-Density) and STM3210B-EVAL (STM32F10x Medium-Density) evaluation boards and can be easily tailored to any other supported device and development board. - STM3210E-EVAL Set-up - 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 - STM3210B-EVAL Set-up - 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. @par How to use it ? In order to make the program work, you must do the following : - Create a project and setup all project configuration - Add the required Library files : - stm32f10x_gpio.c - stm32f10x_i2c.c - stm32f10x_rcc.c - system_stm32f10x.c - Edit stm32f10x.h file to select the device you are working on. @b Tip: You can tailor the provided project template to run this example, for more details please refer to "stm32f10x_stdperiph_lib_um.chm" user manual; select "Peripheral Examples" then follow the instructions provided in "How to proceed" section. - Link all compiled files and load your image into target memory - Run the example @note - Low-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes. - Medium-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 32 and 128 Kbytes. - High-density devices are STM32F101xx and STM32F103xx microcontrollers where the Flash memory density ranges between 256 and 512 Kbytes. *
