Struct rustduino::atmega328p::hal::port::Pin

#[repr(C, packed)]
pub struct Pin {
    pub port: *mut Port,
    pub pin: u8,
}

Represents a single Pin.

The struct contains reference to a Port under which the pin belong and the pin number.

Fields

port: *mut Port

pin: u8

Implementations

impl Pin

pub fn new(port_name: PortName, pin: u8) -> Option<Pin>

Creates a Port of given PortName.

Returns

• maybe a Pin object - which will be used for further implementations.

pub fn set_mode(&mut self, io_mode: IOMode)

Change pin mode to input or output by changing the DDR bit of that pin to 0 and 1 respectively.

io_mode can be either IOMode::Input or IOMode::Output.

Arguments

• mode - a IOMode object, which defines the mode of the pin to be set.

pub fn toggle(&mut self)

Toggles value of PORTxn, independent of value of DDRxn.

pub fn high(&mut self)

Set pin to high.

This function checks if the pin is already high or not by reading PINxn register. If it is not high then it calls Pin::toggle.

pub fn low(&mut self)

Set pin to low.

This function checks if the pin is already low or not by reading PINxn register. If it is not low then it calls Pin::toggle.

pub fn set_output(&mut self)

Change pin mode to output by changing the DDR bit of that pin to 1.

Trait Implementations

impl Clone for Pin

fn clone(&self) -> Pin

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
