mbed_official 340:28d1f895c6fe 15 ##### GPIO Peripheral features #####
mbed_official 340:28d1f895c6fe 16 ==============================================================================
mbed_official 340:28d1f895c6fe 17 [..]
mbed_official 340:28d1f895c6fe 18 Each port bit of the general-purpose I/O (GPIO) ports can be individually
mbed_official 340:28d1f895c6fe 19 configured by software in several modes:
mbed_official 340:28d1f895c6fe 20 (+) Input mode
mbed_official 340:28d1f895c6fe 21 (+) Analog mode
mbed_official 340:28d1f895c6fe 22 (+) Output mode
mbed_official 340:28d1f895c6fe 23 (+) Alternate function mode
mbed_official 340:28d1f895c6fe 24 (+) External interrupt/event lines
mbed_official 340:28d1f895c6fe 25
mbed_official 340:28d1f895c6fe 26 [..]
mbed_official 340:28d1f895c6fe 27 During and just after reset, the alternate functions and external interrupt
mbed_official 340:28d1f895c6fe 28 lines are not active and the I/O ports are configured in input floating mode.
mbed_official 340:28d1f895c6fe 29
mbed_official 340:28d1f895c6fe 30 [..]
mbed_official 340:28d1f895c6fe 31 All GPIO pins have weak internal pull-up and pull-down resistors, which can be
mbed_official 340:28d1f895c6fe 32 activated or not.
mbed_official 340:28d1f895c6fe 33
mbed_official 340:28d1f895c6fe 34 [..]
mbed_official 340:28d1f895c6fe 35 In Output or Alternate mode, each IO can be configured on open-drain or push-pull
mbed_official 340:28d1f895c6fe 36 type and the IO speed can be selected depending on the VDD value.
mbed_official 340:28d1f895c6fe 37
mbed_official 340:28d1f895c6fe 38 [..]
mbed_official 340:28d1f895c6fe 39 The microcontroller IO pins are connected to onboard peripherals/modules through a
mbed_official 340:28d1f895c6fe 40 multiplexer that allows only one peripheral s alternate function (AF) connected
mbed_official 340:28d1f895c6fe 41 to an IO pin at a time. In this way, there can be no conflict between peripherals
mbed_official 340:28d1f895c6fe 42 sharing the same IO pin.
mbed_official 340:28d1f895c6fe 43
mbed_official 340:28d1f895c6fe 44 [..]
mbed_official 340:28d1f895c6fe 45 All ports have external interrupt/event capability. To use external interrupt
mbed_official 340:28d1f895c6fe 46 lines, the port must be configured in input mode. All available GPIO pins are
mbed_official 340:28d1f895c6fe 47 connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
mbed_official 340:28d1f895c6fe 48
mbed_official 340:28d1f895c6fe 49 [..]
mbed_official 340:28d1f895c6fe 50 The external interrupt/event controller consists of up to 23 edge detectors
mbed_official 340:28d1f895c6fe 51 (16 lines are connected to GPIO) for generating event/interrupt requests (each
mbed_official 340:28d1f895c6fe 52 input line can be independently configured to select the type (interrupt or event)
mbed_official 340:28d1f895c6fe 53 and the corresponding trigger event (rising or falling or both). Each line can
mbed_official 340:28d1f895c6fe 54 also be masked independently.

mbed_official 340:28d1f895c6fe 56 ##### How to use this driver #####
mbed_official 340:28d1f895c6fe 57 ==============================================================================
mbed_official 340:28d1f895c6fe 58 [..]

mbed_official 340:28d1f895c6fe 64 structure.
mbed_official 340:28d1f895c6fe 65 (++) In case of Output or alternate function mode selection: the speed is
mbed_official 340:28d1f895c6fe 66 configured through "Speed" member from GPIO_InitTypeDef structure,
mbed_official 340:28d1f895c6fe 67 the speed is configurable: 2 MHz, 10 MHz and 50 MHz.
mbed_official 340:28d1f895c6fe 68 (++) If alternate mode is selected, the alternate function connected to the IO
mbed_official 340:28d1f895c6fe 69 is configured through "Alternate" member from GPIO_InitTypeDef structure
mbed_official 340:28d1f895c6fe 70 (++) Analog mode is required when a pin is to be used as ADC channel
mbed_official 340:28d1f895c6fe 71 or DAC output.
mbed_official 340:28d1f895c6fe 72 (++) In case of external interrupt/event selection the "Mode" member from
mbed_official 340:28d1f895c6fe 73 GPIO_InitTypeDef structure select the type (interrupt or event) and
mbed_official 340:28d1f895c6fe 74 the corresponding trigger event (rising or falling or both).
mbed_official 340:28d1f895c6fe 75
mbed_official 340:28d1f895c6fe 76 (#) In case of external interrupt/event mode selection, configure NVIC IRQ priority
mbed_official 340:28d1f895c6fe 77 mapped to the EXTI line using HAL_NVIC_SetPriority() and enable it using
mbed_official 340:28d1f895c6fe 78 HAL_NVIC_EnableIRQ().
mbed_official 340:28d1f895c6fe 79
mbed_official 340:28d1f895c6fe 80 (#) To get the level of a pin configured in input mode use HAL_GPIO_ReadPin().
mbed_official 340:28d1f895c6fe 81
mbed_official 340:28d1f895c6fe 82 (#) To set/reset the level of a pin configured in output mode use
mbed_official 340:28d1f895c6fe 83 HAL_GPIO_WritePin()/HAL_GPIO_TogglePin().
mbed_official 340:28d1f895c6fe 84
mbed_official 340:28d1f895c6fe 85 (#) To lock pin configuration until next reset use HAL_GPIO_LockPin().
mbed_official 340:28d1f895c6fe 86
mbed_official 340:28d1f895c6fe 87 (#) During and just after reset, the alternate functions are not
mbed_official 340:28d1f895c6fe 88 active and the GPIO pins are configured in input floating mode (except JTAG
mbed_official 340:28d1f895c6fe 89 pins).

mbed_official 340:28d1f895c6fe 92 (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has
mbed_official 340:28d1f895c6fe 93 priority over the GPIO function.
mbed_official 340:28d1f895c6fe 94
mbed_official 340:28d1f895c6fe 95 (#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as
