       [..]
       (#) Enable the GPIO AHB clock using RCC_AHBPeriphClockCmd()
       (#) 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: Low, Medium, Fast or High.
          (++) 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,
               DAC output or comparator input.
       (#) Peripherals alternate function:
          (++) For ADC, DAC and comparators, configure the desired pin in analog
               mode using GPIO_InitStruct->GPIO_Mode = GPIO_Mode_AN
          (++) For other peripherals (TIM, USART...):
