-@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) (only for STM3210C-EVAL).
- - 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 Hardware and Software environment
-
- - This example runs on STM32F10x Connectivity line, High-Density, High-Density
- Value line, Medium-Density, XL-Density, High-Density Value line, Medium-Density
- Value line, Low-Density and Low-Density Value line Devices.
-
- - This example has been tested with STMicroelectronics STM32100E-EVAL (High-Density
- Value line) and STM3210C-EVAL (Connectivity line) evaluation boards
- and can be easily tailored to any other supported device and development
- board.
-
- - STM32100E-EVAL Set-up
- - Use two IO Expanders connected to I2C2 SCL and SDA pins PB10 and PB11 and
- interrupt output pin connected to PA12 (EXTI mode). IO Expander 1 address
- pins is connected to Gnd (address is 0x82).
- - Use LED1, LED2, LED3 and LED4 connected respectively to PF.06, PF.07, PF.08
- and PF.09 pins
- - Use LCD connected to SPI3 remapped pins SCK, MISO and MOSI: PC10, PC11,
- PC12 and the CS pin PB2.
- - Use LCD Touch Screen module connected to IO Expander 1 pins IO_Pin_1,
- IO_Pin_2, IO_Pin_3 and IO_Pin_4 (respectively Y-, X-, Y+, X+ lines).
-
- - STM3210C-EVAL Set-up
- - Use two IO Expanders connected to I2C1 SCL and SDA pins PB6 and PB7 and
- interrupt output pin connected to PB14 (EXTI mode). IO Expander 1 address
- pins is connected to Gnd (address is 0x82) and IO Expander 2 address pins
- is connected to Vcc (address is 0x88).
- - Use LED1, LED2, LED3 and LED4 connected respectively to PD.07, PD.13, PF.03
- and PD.04 pins
- - Use LCD connected to SPI3 remapped pins SCK, MISO and MOSI: PC10, PC11,
- PC12 and the CS pin PB2.
- - Use LCD Touch Screen module connected to IO Expander 1 pins IO_Pin_1,
- IO_Pin_2, IO_Pin_3 and IO_Pin_4 (respectively Y-, X-, Y+, X+ lines).
- - Use Joystick module connected to IO Expander 2 pins IO_Pin_3, IO_Pin_4,
- IO_Pin_5, IO_Pin_6 and IO_Pin_7 (respectively UP, Right, Left, Down and Center)
