-  * @author  MCD Application Team

-  * @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.
