BSP_IO_Init() function

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

Syntax

uint8_t BSP_IO_Init(void);
Implemented in stm324xg_eval_io.c:98

Return value

IO_OK: if all initializations are OK. Other value if error.

Notes

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.

Examples

BSP_IO_Init() is referenced by 1 libraries and example projects.
