- * @file stm32f4xx_gpio.c
- * @author MCD Application Team
- * @version V1.3.0
- * @date 08-November-2013
- * @brief This file provides firmware functions to manage the following
- * functionalities of the GPIO peripheral:
- * + Initialization and Configuration
- * + GPIO Read and Write
- * + GPIO Alternate functions configuration
- *
-@verbatim
- ===============================================================================
- ##### How to use this driver #####
- ===============================================================================
- [..]
- (#) Enable the GPIO AHB clock using the following function
- RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOx, ENABLE);
-
- (#) Configure the GPIO pin(s) using GPIO_Init()
- Four possible configuration are available for each pin:
- (++) Input: Floating, Pull-up, Pull-down.
- (++) Output: Push-Pull (Pull-up, Pull-down or no Pull)
- Open Drain (Pull-up, Pull-down or no Pull). In output mode, the speed
- is configurable: 2 MHz, 25 MHz, 50 MHz or 100 MHz.
- (++) Alternate Function: Push-Pull (Pull-up, Pull-down or no Pull) Open
- Drain (Pull-up, Pull-down or no Pull).
- (++) Analog: required mode when a pin is to be used as ADC channel or DAC
- output.
-
- (#) Peripherals alternate function:
- (++) For ADC and DAC, configure the desired pin in analog mode using
- GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AN;
- (+++) For other peripherals (TIM, USART...):
- (+++) Connect the pin to the desired peripherals' Alternate
- Function (AF) using GPIO_PinAFConfig() function
- (+++) Configure the desired pin in alternate function mode using
- GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AF
- (+++) Select the type, pull-up/pull-down and output speed via
- GPIO_PuPd, GPIO_OType and GPIO_Speed members
- (+++) Call GPIO_Init() function
-
- (#) To get the level of a pin configured in input mode use GPIO_ReadInputDataBit()
-
- (#) To set/reset the level of a pin configured in output mode use
- GPIO_SetBits()/GPIO_ResetBits()
-
- (#) During and just after reset, the alternate functions are not
- active and the GPIO pins are configured in input floating mode (except JTAG
- pins).
-
- (#) The LSE oscillator pins OSC32_IN and OSC32_OUT can be used as general purpose
- (PC14 and PC15, respectively) when the LSE oscillator is off. The LSE has
- priority over the GPIO function.
-
- (#) The HSE oscillator pins OSC_IN/OSC_OUT can be used as
- general purpose PH0 and PH1, respectively, when the HSE oscillator is off.
- The HSE has priority over the GPIO function.
