Function wiringpi::setup

pub fn setup() -> WiringPi<WiringPi>

This initialises the wiringPi system and assumes that the calling program is going to be using the wiringPi pin numbering scheme.

This is a simplified numbering scheme which provides a mapping from virtual pin numbers 0 through 16 to the real underlying Broadcom GPIO pin numbers. See the pins page for a table which maps the wiringPi pin number to the Broadcom GPIO pin number to the physical location on the edge connector.

This function needs to be called with root privileges.
