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 Directory contents - - - I2C/IOExpander/stm32f10x_conf.h Library Configuration file - - I2C/IOExpander/stm32f10x_it.c Interrupt handlers - - I2C/IOExpander/stm32f10x_it.h Header for stm32f10x_it.c - - I2C/IOExpander/main.c Main program - - I2C/IOExpander/main.h Header for main.c - - I2C/IOExpander/system_stm32f10x.c STM32F10x system source file - - -@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).
