Crate inverted_pin 

This provides implementations of the input/output pin embedded-hal traits with inverted logic.

For example, an InvertedPin can wrap an OutputPin and when setting it low, it will set the wrapped OutputPin high. It works similarly for an InputPin as well.

This is useful when dealing with pins that use a logic that is inverted with respect to what the rest of the system expects.

Since an InvertedPin implements the OutputPin and InputPin traits as well, it can be used just like any other OutputPin or InputPin and serves as a drop-in replacement of the wrapped pin.

Usage examples

Output InvertedPin interaction

use linux_embedded_hal::SysfsPin;
use inverted_pin::InvertedPin;

let pin = SysfsPin::new(25);
let mut inverted_pin = InvertedPin::new(pin);

// This calls `pin.set_low()`
inverted_pin.set_high().unwrap();

Input InvertedPin interaction

use linux_embedded_hal::SysfsPin;
use inverted_pin::InvertedPin;

let pin = SysfsPin::new(25);
let mut inverted_pin = InvertedPin::new(pin);

// This returns the result of calling `pin.is_low()`
inverted_pin.is_high().unwrap();
