lypinator | 0:bb348c97df44 | 13 | ##### GPIO Peripheral features ##### |
lypinator | 0:bb348c97df44 | 14 | ============================================================================== |
lypinator | 0:bb348c97df44 | 15 | [..] |
lypinator | 0:bb348c97df44 | 16 | Subject to the specific hardware characteristics of each I/O port listed in the datasheet, each |
lypinator | 0:bb348c97df44 | 17 | port bit of the General Purpose IO (GPIO) Ports, can be individually configured by software |
lypinator | 0:bb348c97df44 | 18 | in several modes: |
lypinator | 0:bb348c97df44 | 19 | (+) Input mode |
lypinator | 0:bb348c97df44 | 20 | (+) Analog mode |
lypinator | 0:bb348c97df44 | 21 | (+) Output mode |
lypinator | 0:bb348c97df44 | 22 | (+) Alternate function mode |
lypinator | 0:bb348c97df44 | 23 | (+) External interrupt/event lines |
lypinator | 0:bb348c97df44 | 24 | |
lypinator | 0:bb348c97df44 | 25 | [..] |
lypinator | 0:bb348c97df44 | 26 | During and just after reset, the alternate functions and external interrupt |
lypinator | 0:bb348c97df44 | 27 | lines are not active and the I/O ports are configured in input floating mode. |
lypinator | 0:bb348c97df44 | 28 | |
lypinator | 0:bb348c97df44 | 29 | [..] |
lypinator | 0:bb348c97df44 | 30 | All GPIO pins have weak internal pull-up and pull-down resistors, which can be |
lypinator | 0:bb348c97df44 | 31 | activated or not. |
lypinator | 0:bb348c97df44 | 32 | |
lypinator | 0:bb348c97df44 | 33 | [..] |
lypinator | 0:bb348c97df44 | 34 | In Output or Alternate mode, each IO can be configured on open-drain or push-pull |
lypinator | 0:bb348c97df44 | 35 | type and the IO speed can be selected depending on the VDD value. |
lypinator | 0:bb348c97df44 | 36 | |
lypinator | 0:bb348c97df44 | 37 | [..] |
lypinator | 0:bb348c97df44 | 38 | All ports have external interrupt/event capability. To use external interrupt |
lypinator | 0:bb348c97df44 | 39 | lines, the port must be configured in input mode. All available GPIO pins are |
lypinator | 0:bb348c97df44 | 40 | connected to the 16 external interrupt/event lines from EXTI0 to EXTI15. |
lypinator | 0:bb348c97df44 | 41 | |
lypinator | 0:bb348c97df44 | 42 | [..] |
lypinator | 0:bb348c97df44 | 43 | The external interrupt/event controller consists of up to 23 edge detectors |
lypinator | 0:bb348c97df44 | 44 | (16 lines are connected to GPIO) for generating event/interrupt requests (each |
lypinator | 0:bb348c97df44 | 45 | input line can be independently configured to select the type (interrupt or event) |
lypinator | 0:bb348c97df44 | 46 | and the corresponding trigger event (rising or falling or both). Each line can |
lypinator | 0:bb348c97df44 | 47 | also be masked independently. |
lypinator | 0:bb348c97df44 | 48 | |
lypinator | 0:bb348c97df44 | 49 | ##### How to use this driver ##### |
lypinator | 0:bb348c97df44 | 50 | ============================================================================== |
lypinator | 0:bb348c97df44 | 51 | [..] |
lypinator | 0:bb348c97df44 | 52 | (#) Enable the GPIO AHB clock using the following function: __HAL_RCC_GPIOx_CLK_ENABLE(). |
lypinator | 0:bb348c97df44 | 53 | |
lypinator | 0:bb348c97df44 | 54 | (#) Configure the GPIO pin(s) using HAL_GPIO_Init(). |
lypinator | 0:bb348c97df44 | 55 | (++) Configure the IO mode using "Mode" member from GPIO_InitTypeDef structure |
lypinator | 0:bb348c97df44 | 56 | (++) Activate Pull-up, Pull-down resistor using "Pull" member from GPIO_InitTypeDef |
lypinator | 0:bb348c97df44 | 57 | structure. |
lypinator | 0:bb348c97df44 | 58 | (++) In case of Output or alternate function mode selection: the speed is |
lypinator | 0:bb348c97df44 | 59 | configured through "Speed" member from GPIO_InitTypeDef structure. |
lypinator | 0:bb348c97df44 | 60 | (++) In alternate mode is selection, the alternate function connected to the IO |
lypinator | 0:bb348c97df44 | 61 | is configured through "Alternate" member from GPIO_InitTypeDef structure. |
lypinator | 0:bb348c97df44 | 62 | (++) Analog mode is required when a pin is to be used as ADC channel |
lypinator | 0:bb348c97df44 | 63 | or DAC output. |
lypinator | 0:bb348c97df44 | 64 | (++) In case of external interrupt/event selection the "Mode" member from |
lypinator | 0:bb348c97df44 | 65 | GPIO_InitTypeDef structure select the type (interrupt or event) and |
lypinator | 0:bb348c97df44 | 66 | the corresponding trigger event (rising or falling or both). |
lypinator | 0:bb348c97df44 | 67 | |
lypinator | 0:bb348c97df44 | 68 | (#) In case of external interrupt/event mode selection, configure NVIC IRQ priority |
lypinator | 0:bb348c97df44 | 69 | mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using |
lypinator | 0:bb348c97df44 | 70 | HAL_NVIC_EnableIRQ(). |
lypinator | 0:bb348c97df44 | 71 | |
lypinator | 0:bb348c97df44 | 72 | (#) To get the level of a pin configured in input mode use HAL_GPIO_ReadPin(). |
lypinator | 0:bb348c97df44 | 73 | |
lypinator | 0:bb348c97df44 | 74 | (#) To set/reset the level of a pin configured in output mode use |
lypinator | 0:bb348c97df44 | 75 | HAL_GPIO_WritePin()/HAL_GPIO_TogglePin(). |
lypinator | 0:bb348c97df44 | 76 | |
lypinator | 0:bb348c97df44 | 77 | (#) To lock pin configuration until next reset use HAL_GPIO_LockPin(). |
lypinator | 0:bb348c97df44 | 78 | |
lypinator | 0:bb348c97df44 | 79 | |
lypinator | 0:bb348c97df44 | 80 | (#) During and just after reset, the alternate functions are not |
lypinator | 0:bb348c97df44 | 81 | active and the GPIO pins are configured in input floating mode (except JTAG |
lypinator | 0:bb348c97df44 | 82 | pins). |
lypinator | 0:bb348c97df44 | 83 | |
lypinator | 0:bb348c97df44 | 84 | (#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose |
lypinator | 0:bb348c97df44 | 85 | (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has |
lypinator | 0:bb348c97df44 | 86 | priority over the GPIO function. |
lypinator | 0:bb348c97df44 | 87 | |
lypinator | 0:bb348c97df44 | 88 | (#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as |
lypinator | 0:bb348c97df44 | 89 | general purpose PH0 and PH1, respectively, when the HSE oscillator is off. |
lypinator | 0:bb348c97df44 | 90 | The HSE has priority over the GPIO function. |
