mbed_official 76:aeb1df146756 17 [..]
mbed_official 76:aeb1df146756 18 (#) Enable the GPIO AHB clock using RCC_AHBPeriphClockCmd()
mbed_official 76:aeb1df146756 19 (#) Configure the GPIO pin(s) using GPIO_Init()
mbed_official 76:aeb1df146756 20 Four possible configuration are available for each pin:
mbed_official 76:aeb1df146756 21 (++) Input: Floating, Pull-up, Pull-down.
mbed_official 76:aeb1df146756 22 (++) Output: Push-Pull (Pull-up, Pull-down or no Pull)
mbed_official 76:aeb1df146756 23 Open Drain (Pull-up, Pull-down or no Pull).
mbed_official 76:aeb1df146756 24 In output mode, the speed is configurable: Very Low, Low,
mbed_official 76:aeb1df146756 25 Medium or High.
mbed_official 76:aeb1df146756 26 (++) Alternate Function: Push-Pull (Pull-up, Pull-down or no Pull)
mbed_official 76:aeb1df146756 27 Open Drain (Pull-up, Pull-down or no Pull).
mbed_official 76:aeb1df146756 28 (++) Analog: required mode when a pin is to be used as ADC channel,
mbed_official 76:aeb1df146756 29 DAC output or comparator input.
mbed_official 76:aeb1df146756 30 (#) Peripherals alternate function:
mbed_official 76:aeb1df146756 31 (++) For ADC, DAC and comparators, configure the desired pin in
mbed_official 76:aeb1df146756 32 analog mode using GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AN
mbed_official 76:aeb1df146756 33 (++) For other peripherals (TIM, USART...):
mbed_official 76:aeb1df146756 34 (+++) Connect the pin to the desired peripherals' Alternate
mbed_official 76:aeb1df146756 35 Function (AF) using GPIO_PinAFConfig() function.
mbed_official 76:aeb1df146756 36 (+++) Configure the desired pin in alternate function mode using
mbed_official 76:aeb1df146756 37 GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AF
mbed_official 76:aeb1df146756 38 (+++) Select the type, pull-up/pull-down and output speed via
mbed_official 76:aeb1df146756 39 GPIO_PuPd, GPIO_OType and GPIO_Speed members.
mbed_official 76:aeb1df146756 40 (+++) Call GPIO_Init() function.
mbed_official 76:aeb1df146756 41 (#) To get the level of a pin configured in input mode use GPIO_ReadInputDataBit()
mbed_official 76:aeb1df146756 42 (#) To set/reset the level of a pin configured in output mode use
mbed_official 76:aeb1df146756 43 GPIO_SetBits()/GPIO_ResetBits()
mbed_official 76:aeb1df146756 44 (#) During and just after reset, the alternate functions are not
mbed_official 76:aeb1df146756 45 active and the GPIO pins are configured in input floating mode
mbed_official 76:aeb1df146756 46 (except JTAG pins).
mbed_official 76:aeb1df146756 47 (#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as
mbed_official 76:aeb1df146756 48 general-purpose (PC14 and PC15, respectively) when the LSE
mbed_official 76:aeb1df146756 49 oscillator is off. The LSE has priority over the GPIO function.
mbed_official 76:aeb1df146756 50 (#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as
mbed_official 76:aeb1df146756 51 general-purpose PH0 and PH1, respectively, when the HSE
mbed_official 76:aeb1df146756 52 oscillator is off. The HSE has priority over the GPIO function.
