4 * @author MCD Application Team
5 * @version V1.6.0
6 * @date 28-October-2016
7 * @brief GPIO HAL module driver.
8 * This file provides firmware functions to manage the following
9 * functionalities of the General Purpose Input/Output (GPIO) peripheral:
10 * + Initialization and de-initialization functions
11 * + IO operation functions
12 *
13 @verbatim
14 ==============================================================================
15 ##### GPIO Peripheral features #####
16 ==============================================================================
17 [..]
18 (+) Each port bit of the general-purpose I/O (GPIO) ports can be individually
19 configured by software in several modes:
20 (++) Input mode
21 (++) Analog mode
22 (++) Output mode
23 (++) Alternate function mode
24 (++) External interrupt/event lines
25
26 (+) During and just after reset, the alternate functions and external interrupt
27 lines are not active and the I/O ports are configured in input floating mode.
28
29 (+) All GPIO pins have weak internal pull-up and pull-down resistors, which can be
30 activated or not.
31
32 (+) In Output or Alternate mode, each IO can be configured on open-drain or push-pull
33 type and the IO speed can be selected depending on the VDD value.
34
35 (+) The microcontroller IO pins are connected to onboard peripherals/modules through a
36 multiplexer that allows only one peripheral alternate function (AF) connected
37 to an IO pin at a time. In this way, there can be no conflict between peripherals
38 sharing the same IO pin.
39
40 (+) All ports have external interrupt/event capability. To use external interrupt
41 lines, the port must be configured in input mode. All available GPIO pins are
42 connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
43
44 (+) The external interrupt/event controller consists of up to 39 edge detectors
45 (16 lines are connected to GPIO) for generating event/interrupt requests (each
46 input line can be independently configured to select the type (interrupt or event)
47 and the corresponding trigger event (rising or falling or both). Each line can
48 also be masked independently.
49
50 ##### How to use this driver #####
51 ==============================================================================
52 [..]
53 (#) Enable the GPIO AHB clock using the following function: __HAL_RCC_GPIOx_CLK_ENABLE().
54
55 (#) Configure the GPIO pin(s) using HAL_GPIO_Init().
56 (++) Configure the IO mode using "Mode" member from GPIO_InitTypeDef structure
57 (++) Activate Pull-up, Pull-down resistor using "Pull" member from GPIO_InitTypeDef
58 structure.
59 (++) In case of Output or alternate function mode selection: the speed is
60 configured through "Speed" member from GPIO_InitTypeDef structure.
61 (++) In alternate mode is selection, the alternate function connected to the IO
62 is configured through "Alternate" member from GPIO_InitTypeDef structure.
63 (++) Analog mode is required when a pin is to be used as ADC channel
64 or DAC output.
65 (++) In case of external interrupt/event selection the "Mode" member from
66 GPIO_InitTypeDef structure select the type (interrupt or event) and
67 the corresponding trigger event (rising or falling or both).
68
69 (#) In case of external interrupt/event mode selection, configure NVIC IRQ priority
70 mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using
71 HAL_NVIC_EnableIRQ().
72
73 (#) To get the level of a pin configured in input mode use HAL_GPIO_ReadPin().
74
75 (#) To set/reset the level of a pin configured in output mode use
76 HAL_GPIO_WritePin()/HAL_GPIO_TogglePin().
77
78 (#) To lock pin configuration until next reset use HAL_GPIO_LockPin().
79
80 (#) During and just after reset, the alternate functions are not
81 active and the GPIO pins are configured in input floating mode (except JTAG
82 pins).
83
84 (#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose
85 (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has
86 priority over the GPIO function.
87
88 (#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as
89 general purpose PH0 and PH1, respectively, when the HSE oscillator is off.
90 The HSE has priority over the GPIO function.
