void gpio_setup_input_pulldown ( ioportid_t  port,
uint16_t  gpios 
)

Setup one or more pins of the given GPIO port as inputs with pull down resistors enabled.

Parameters

void gpio_setup_pin_af ( ioportid_t  port,
uint16_t  pin,
uint8_t  af,
bool  is_output 
)

Setup a gpio for input or output with alternate function.

This is an STM32 specific helper funtion and should only be used in stm32 code.
