STM32F429I DISCOVERY IO Private Functions
[STM32F429I DISCOVERY IO]

Configures the IO pin(s) according to IO mode structure value.

Parameters:

IoPin,:	IO pin(s) to be configured. This parameter could be any combination of the following values: STMPE811_PIN_x: where x can be from 0 to 7.
IoMode,:	The IO pin mode to configure, could be one of the following values: IO_MODE_INPUT IO_MODE_OUTPUT IO_MODE_IT_RISING_EDGE IO_MODE_IT_FALLING_EDGE IO_MODE_IT_LOW_LEVEL IO_MODE_IT_HIGH_LEVEL

Definition at line 160 of file stm32f429i_discovery_io.c.

Initializes and configures the IO functionalities and configures all necessary hardware resources (GPIOs, clocks..).

Note:

BSP_IO_Init() is using HAL_Delay() function to ensure that stmpe811 IO Expander is correctly reset. HAL_Delay() function provides accurate delay (in milliseconds) based on variable incremented in SysTick ISR. This implies that if BSP_IO_Init() is called from a peripheral ISR process, then the SysTick interrupt must have higher priority (numerically lower) than the peripheral interrupt. Otherwise the caller ISR process will be blocked.

Return values:

IO_OK

if all initializations done correctly. Other value if error.
