WebWhat would be the best way to reconfigure a pin from Input to Output and vice versa on the flight? The STM function HAL_GPIO_Init() is quite long so I would rather not use that function just to change a mode Input/Output. What would be the most efficient way to change a pin I/O mode once it has been initially configured? Thanks.
