Abstraction of PCA9539
Abstraction for I/O expander PCA9539. This crate offers the following features:
- Individual pin instances, fully implementing digital::v2 traits of embedded_hal
- Central I/O control, s. PCA9539 module
- Two state management modes for reduced I2C overhead, s. pins module
- Three concurrency models, s. concurrency section
- no_std support
Example
use rca9539::example::DummyI2CBus;
use rca9539::expander::Bank::Bank0;
use rca9539::expander::PCA9539;
use rca9539::expander::PinID::Pin1;
use embedded_hal::digital::v2::InputPin;
let i2c_bus = DummyI2CBus::new();
let mut expander = PCA9539::new(i2c_bus);
let pins = expander.pins();
let pin01 = pins.get_pin(Bank0, Pin1);
assert!(pin01.is_high().unwrap());
