sahilmgandhi 18:6a4db94011d3 15 ##### GPIO Peripheral features #####
sahilmgandhi 18:6a4db94011d3 16 ==============================================================================
sahilmgandhi 18:6a4db94011d3 17 [..]
sahilmgandhi 18:6a4db94011d3 18 Subject to the specific hardware characteristics of each I/O port listed in the datasheet, each
sahilmgandhi 18:6a4db94011d3 19 port bit of the General Purpose IO (GPIO) Ports, can be individually configured by software
sahilmgandhi 18:6a4db94011d3 20 in several modes:
sahilmgandhi 18:6a4db94011d3 21 (+) Input mode
sahilmgandhi 18:6a4db94011d3 22 (+) Analog mode
sahilmgandhi 18:6a4db94011d3 23 (+) Output mode
sahilmgandhi 18:6a4db94011d3 24 (+) Alternate function mode
sahilmgandhi 18:6a4db94011d3 25 (+) External interrupt/event lines
sahilmgandhi 18:6a4db94011d3 26
sahilmgandhi 18:6a4db94011d3 27 [..]
sahilmgandhi 18:6a4db94011d3 28 During and just after reset, the alternate functions and external interrupt
sahilmgandhi 18:6a4db94011d3 29 lines are not active and the I/O ports are configured in input floating mode.
sahilmgandhi 18:6a4db94011d3 30
sahilmgandhi 18:6a4db94011d3 31 [..]
sahilmgandhi 18:6a4db94011d3 32 All GPIO pins have weak internal pull-up and pull-down resistors, which can be
sahilmgandhi 18:6a4db94011d3 33 activated or not.
sahilmgandhi 18:6a4db94011d3 34
sahilmgandhi 18:6a4db94011d3 35 [..]
sahilmgandhi 18:6a4db94011d3 36 In Output or Alternate mode, each IO can be configured on open-drain or push-pull
sahilmgandhi 18:6a4db94011d3 37 type and the IO speed can be selected depending on the VDD value.
sahilmgandhi 18:6a4db94011d3 38
sahilmgandhi 18:6a4db94011d3 39 [..]
sahilmgandhi 18:6a4db94011d3 40 All ports have external interrupt/event capability. To use external interrupt
sahilmgandhi 18:6a4db94011d3 41 lines, the port must be configured in input mode. All available GPIO pins are
sahilmgandhi 18:6a4db94011d3 42 connected to the 16 external interrupt/event lines from EXTI0 to EXTI15.
sahilmgandhi 18:6a4db94011d3 43
sahilmgandhi 18:6a4db94011d3 44 [..]
sahilmgandhi 18:6a4db94011d3 45 The external interrupt/event controller consists of up to 23 edge detectors
sahilmgandhi 18:6a4db94011d3 46 (16 lines are connected to GPIO) for generating event/interrupt requests (each
sahilmgandhi 18:6a4db94011d3 47 input line can be independently configured to select the type (interrupt or event)
sahilmgandhi 18:6a4db94011d3 48 and the corresponding trigger event (rising or falling or both). Each line can
sahilmgandhi 18:6a4db94011d3 49 also be masked independently.

sahilmgandhi 18:6a4db94011d3 51 ##### How to use this driver #####

sahilmgandhi 18:6a4db94011d3 61 configured through "Speed" member from GPIO_InitTypeDef structure.
sahilmgandhi 18:6a4db94011d3 62 (++) In alternate mode is selection, the alternate function connected to the IO
sahilmgandhi 18:6a4db94011d3 63 is configured through "Alternate" member from GPIO_InitTypeDef structure.
sahilmgandhi 18:6a4db94011d3 64 (++) Analog mode is required when a pin is to be used as ADC channel
sahilmgandhi 18:6a4db94011d3 65 or DAC output.
sahilmgandhi 18:6a4db94011d3 66 (++) In case of external interrupt/event selection the "Mode" member from
sahilmgandhi 18:6a4db94011d3 67 GPIO_InitTypeDef structure select the type (interrupt or event) and
sahilmgandhi 18:6a4db94011d3 68 the corresponding trigger event (rising or falling or both).

sahilmgandhi 18:6a4db94011d3 81

sahilmgandhi 18:6a4db94011d3 83 active and the GPIO pins are configured in input floating mode (except JTAG
sahilmgandhi 18:6a4db94011d3 84 pins).

sahilmgandhi 18:6a4db94011d3 87 (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has
sahilmgandhi 18:6a4db94011d3 88 priority over the GPIO function.
