/** @page I2C_IOE Example on how to use the IO Expander @verbatim ******************** (C) COPYRIGHT 2011 STMicroelectronics ******************* * @file I2C/IOE/readme.txt * @author MCD Application Team * @version V1.0.0 * @date 18-April-2011 * @brief Description of the I2C IOExpander example. ****************************************************************************** * THE PRESENT FIRMWARE WHICH IS FOR GUIDANCE ONLY AIMS AT PROVIDING CUSTOMERS * WITH CODING INFORMATION REGARDING THEIR PRODUCTS IN ORDER FOR THEM TO SAVE * TIME. AS A RESULT, STMICROELECTRONICS SHALL NOT BE HELD LIABLE FOR ANY * DIRECT, INDIRECT OR CONSEQUENTIAL DAMAGES WITH RESPECT TO ANY CLAIMS ARISING * FROM THE CONTENT OF SUCH FIRMWARE AND/OR THE USE MADE BY CUSTOMERS OF THE * CODING INFORMATION CONTAINED HEREIN IN CONNECTION WITH THEIR PRODUCTS. ****************************************************************************** @endverbatim @par Example Description This firmware provides an example of configuring and using the IO Expander STMPE811 in order to control input Joystick IOs, output IOs and the Touch Screen feature. This example provides the elementary steps to control the following modules and use them in an application: The IO pins are used for: - Getting Joystick pins status (Polling and interrupt) only for STM3210C-EVAL. - The Touch Screen controller is used to get the Touched area detection information in a single point mode (Polling and interrupt). The input information can be used either in Polling mode (uncomment the define #define IOE_POLLING_MODE) or in Interrupt mode (uncomment the define #define IOE_INTERRUPT_MODE). These defines are in main.h file. After configuring the IO Expander modules and Interrupts (if needed), the output IOs are set to their default state. These operations are done by the functions: IOE_Config() and IOE_ITConfig(). If the IO Expander is not operational (or the I2C pins are not in the correct level) the IOE_Config() function returns a value different from 0 and a message is displayed on the LCD screen. To get the status of an input: - IOE_JoyStickGetState() function is used for Joystick and returns a JOY_State_TypeDef value indicating the currently pressed key. This information is used to update the LCD display (the Joystick pressed key name is displayed). - IOE_TS_GetState() function is used for Touch Screen and returns a pointer to a structure holding the Touch Screen status (did a Touch Detection happened, X, Y, and Z positions). Only detection into the drawn rectangles areas is considered and used to update the LEDs status and LCD display (corresponding LED turned ON when its rectangle is touched, and the LED name is displayed on the LCD screen). Besides, the examples checks the status of the other Push-Buttons implemented on the board (Key, Tamper and WakeUp push-buttons). They are checked in parallel with the IO Expander IOs and the LCD display and LEDs are updated according to the push buttons state. @par Directory contents - I2C/IOE/system_stm32f2xx.c STM32F2xx system clock configuration file - I2C/IOE/stm32f2xx_conf.h Library Configuration file - I2C/IOE/stm32f2xx_it.c Interrupt handlers - I2C/IOE/stm32f2xx_it.h Interrupt handlers header file - I2C/IOE/main.c Main program @note The "system_stm32f2xx.c" is generated by an automatic clock configuration tool and can be easily customized to your own configuration. To select different clock setup, use the "STM32F2xx_Clock_Configuration_V1.0.0.xls" tool. @par Hardware and Software environment - This example runs on STM32F2xx Devices. - This example has been tested with STM322xG-EVAL RevB (with no additional hardware), and can be easily tailored to any other development board. @par How to use it ? In order to make the program work, you must do the following : - Copy all source files from this example folder to the template folder under Project\STM32F2xx_StdPeriph_Template - Open your preferred toolchain - Rebuild all files and load your image into target memory - Run the example *
