mbed_official | 235:685d5f11838f | 15 | ##### GPIO Peripheral features ##### |
mbed_official | 235:685d5f11838f | 16 | ============================================================================== |
mbed_official | 235:685d5f11838f | 17 | [..] |
mbed_official | 235:685d5f11838f | 18 | (+) Each port bit of the general-purpose I/O (GPIO) ports can be individually |
mbed_official | 235:685d5f11838f | 19 | configured by software in several modes: |
mbed_official | 235:685d5f11838f | 20 | (++) Input mode |
mbed_official | 235:685d5f11838f | 21 | (++) Analog mode |
mbed_official | 235:685d5f11838f | 22 | (++) Output mode |
mbed_official | 235:685d5f11838f | 23 | (++) Alternate function mode |
mbed_official | 235:685d5f11838f | 24 | (++) External interrupt/event lines |
mbed_official | 235:685d5f11838f | 25 | |
mbed_official | 235:685d5f11838f | 26 | (+) During and just after reset, the alternate functions and external interrupt |
mbed_official | 235:685d5f11838f | 27 | lines are not active and the I/O ports are configured in input floating mode. |
mbed_official | 235:685d5f11838f | 28 | |
mbed_official | 235:685d5f11838f | 29 | (+) All GPIO pins have weak internal pull-up and pull-down resistors, which can be |
mbed_official | 235:685d5f11838f | 30 | activated or not. |
mbed_official | 235:685d5f11838f | 31 | |
mbed_official | 235:685d5f11838f | 32 | (+) In Output or Alternate mode, each IO can be configured on open-drain or push-pull |
mbed_official | 235:685d5f11838f | 33 | type and the IO speed can be selected depending on the VDD value. |
mbed_official | 235:685d5f11838f | 34 | |
mbed_official | 235:685d5f11838f | 35 | (+) The microcontroller IO pins are connected to onboard peripherals/modules through a |
mbed_official | 235:685d5f11838f | 36 | multiplexer that allows only one peripheral alternate function (AF) connected |
mbed_official | 235:685d5f11838f | 37 | to an IO pin at a time. In this way, there can be no conflict between peripherals |
mbed_official | 235:685d5f11838f | 38 | sharing the same IO pin. |
mbed_official | 235:685d5f11838f | 39 | |
mbed_official | 235:685d5f11838f | 40 | (+) All ports have external interrupt/event capability. To use external interrupt |
mbed_official | 235:685d5f11838f | 41 | lines, the port must be configured in input mode. All available GPIO pins are |
mbed_official | 235:685d5f11838f | 42 | connected to the 16 external interrupt/event lines from EXTI0 to EXTI15. |
mbed_official | 235:685d5f11838f | 43 | |
mbed_official | 235:685d5f11838f | 44 | (+) The external interrupt/event controller consists of up to 23 edge detectors |
mbed_official | 235:685d5f11838f | 45 | (16 lines are connected to GPIO) for generating event/interrupt requests (each |
mbed_official | 235:685d5f11838f | 46 | input line can be independently configured to select the type (interrupt or event) |
mbed_official | 235:685d5f11838f | 47 | and the corresponding trigger event (rising or falling or both). Each line can |
mbed_official | 235:685d5f11838f | 48 | also be masked independently. |

mbed_official | 235:685d5f11838f | 50 | ##### How to use this driver ##### |
mbed_official | 235:685d5f11838f | 51 | ============================================================================== |

mbed_official | 235:685d5f11838f | 58 | structure. |
mbed_official | 235:685d5f11838f | 59 | (++) In case of Output or alternate function mode selection: the speed is |
mbed_official | 235:685d5f11838f | 60 | configured through "Speed" member from GPIO_InitTypeDef structure. |
mbed_official | 235:685d5f11838f | 61 | (++) In alternate mode is selection, the alternate function connected to the IO |
mbed_official | 235:685d5f11838f | 62 | is configured through "Alternate" member from GPIO_InitTypeDef structure. |
mbed_official | 235:685d5f11838f | 63 | (++) Analog mode is required when a pin is to be used as ADC channel |
mbed_official | 235:685d5f11838f | 64 | or DAC output. |
mbed_official | 235:685d5f11838f | 65 | (++) In case of external interrupt/event selection the "Mode" member from |
mbed_official | 235:685d5f11838f | 66 | GPIO_InitTypeDef structure select the type (interrupt or event) and |
mbed_official | 235:685d5f11838f | 67 | the corresponding trigger event (rising or falling or both). |
mbed_official | 235:685d5f11838f | 68 | |
mbed_official | 235:685d5f11838f | 69 | (#) In case of external interrupt/event mode selection, configure NVIC IRQ priority |
mbed_official | 235:685d5f11838f | 70 | mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using |
mbed_official | 235:685d5f11838f | 71 | HAL_NVIC_EnableIRQ(). |
mbed_official | 235:685d5f11838f | 72 | |

mbed_official | 235:685d5f11838f | 75 | (#) To set/reset the level of a pin configured in output mode use |

mbed_official | 235:685d5f11838f | 77 | |
mbed_official | 235:685d5f11838f | 78 | (#) During and just after reset, the alternate functions are not |
mbed_official | 235:685d5f11838f | 79 | active and the GPIO pins are configured in input floating mode (except JTAG |
mbed_official | 235:685d5f11838f | 80 | pins). |

mbed_official | 235:685d5f11838f | 83 | (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has |
mbed_official | 235:685d5f11838f | 84 | priority over the GPIO function. |
