- * @brief GPIO HAL module driver.
- * This file provides firmware functions to manage the following
- * functionalities of the General Purpose Input/Output (GPIO) peripheral:
- * + Initialization and de-initialization functions
- * + IO operation functions
- *
- @verbatim
- ==============================================================================
- ##### GPIO Peripheral features #####
- ==============================================================================
- [..]
- (+) Each port bit of the general-purpose I/O (GPIO) ports can be individually
- configured by software in several modes:
- (++) Input mode
- (++) Analog mode
- (++) Output mode
- (++) Alternate function mode
- (++) External interrupt/event lines
-
- (+) During and just after reset, the alternate functions and external interrupt
- lines are not active and the I/O ports are configured in input floating mode.
-
- (+) All GPIO pins have weak internal pull-up and pull-down resistors, which can be
- activated or not.
-
- (+) In Output or Alternate mode, each IO can be configured on open-drain or push-pull
- type and the IO speed can be selected depending on the VDD value.
-
- (+) The microcontroller IO pins are connected to onboard peripherals/modules through a
- multiplexer that allows only one peripheral alternate function (AF) connected
- to an IO pin at a time. In this way, there can be no conflict between peripherals
- sharing the same IO pin.
-
- (+) All ports have external interrupt/event capability. To use external interrupt
- lines, the port must be configured in input mode. All available GPIO pins are
- connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
-
- (+) The external interrupt/event controller consists of up to 28 edge detectors
- (16 lines are connected to GPIO) for generating event/interrupt requests (each
- input line can be independently configured to select the type (interrupt or event)
- and the corresponding trigger event (rising or falling or both). Each line can
- also be masked independently.
-
- ##### How to use this driver #####
- ==============================================================================
- [..]
- (#) Enable the GPIO AHB clock using the following function : __HAL_RCC_GPIOx_CLK_ENABLE().
-
- (#) Configure the GPIO pin(s) using HAL_GPIO_Init().
- (++) Configure the IO mode using "Mode" member from GPIO_InitTypeDef structure
- (++) Activate Pull-up, Pull-down resistor using "Pull" member from GPIO_InitTypeDef
- structure.
- (++) In case of Output or alternate function mode selection: the speed is
- configured through "Speed" member from GPIO_InitTypeDef structure.
- (++) In alternate mode is selection, the alternate function connected to the IO
- is configured through "Alternate" member from GPIO_InitTypeDef structure.
- (++) Analog mode is required when a pin is to be used as ADC channel
- or DAC output.
- (++) In case of external interrupt/event selection the "Mode" member from
- GPIO_InitTypeDef structure select the type (interrupt or event) and
- the corresponding trigger event (rising or falling or both).
-
- (#) In case of external interrupt/event mode selection, configure NVIC IRQ priority
- mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using
- HAL_NVIC_EnableIRQ().
-
- (#) HAL_GPIO_DeInit allows to set register values to their reset value. It's also
- recommended to use it to unconfigure pin which was used as an external interrupt
- or in event mode. That's the only way to reset corresponding bit in EXTI & SYSCFG
- registers.
-
- (#) To get the level of a pin configured in input mode use HAL_GPIO_ReadPin().
-
- (#) To set/reset the level of a pin configured in output mode use
- HAL_GPIO_WritePin()/HAL_GPIO_TogglePin().
-
- (#) To lock pin configuration until next reset use HAL_GPIO_LockPin().
-
- (#) During and just after reset, the alternate functions are not
- active and the GPIO pins are configured in input floating mode (except JTAG
- pins).
-
- (#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose
- (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has
- priority over the GPIO function.
-
- (#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as
- general purpose PF0 and PF1, respectively, when the HSE oscillator is off.
- The HSE has priority over the GPIO function.
