Release v0.2.0

rust_gpiozero now uses Rust 2018 edition and rppal for gpio access

• input_devices

  • InputDevice changes:

    • pin is now u8
    • new configures device with the pin pulled to low by default
    • Added new_with_pullup: create InputDevice with the pin number given with the pin pulled high with an internal resistor by default
    • value returns a bool

  • DigitalInputDevice changes:

    • pin is now u8
    • new configures device with the pin pulled to low by default
    • Added new_with_pullup: create InputDevice with the pin number given with the pin pulled high with an internal resistor by default
    • value returns a bool
    • wait_for_inactive takes an argument timeout (Option)
    • wait_for_active takes an argument timeout (Option)

  • Button changes:

    • pin is now u8
    • new configures device with the pin pulled to high by default
    • Added new_with_pulldown: create InputDevice with the pin number given with the pin pulled low with an internal resistor by default
    • value returns a bool
    • wait_for_inactive takes an argument timeout (Option)
    • wait_for_active takes an argument timeout (Option)

• output_devices

  • PWMOutputDevice (New)

    • A generic output device configured for software pulse-width modulation (PWM)
    • Values can be specified between 0.0 and 1.0 for varying levels of power in the device.

  • PWMLED (New)

    • Represents a light emitting diode (LED) with variable brightness.
    • Values can be specified between 0.0 and 1.0 for varying levels of brightness.

  • Servo (New)

    • Represents a PWM-controlled servo motor connected to a GPIO pin

  • OutputDevice changes:

    • pin is now u8
    • Added active_high: When True, the value property is True when the device's pin is high. When False the value property is True when the device's pin is low (i.e. the value is inverted).
    • Added set_active_high to set the state for active_high

  • DigitalOutputDevice changes:

    • pin is now u8
    • Added active_high: When True, the value property is True when the device's pin is high. When False the value property is True when the device's pin is low (i.e. the value is inverted).
    • Added set_active_high to set the state for active_high
    • Added blink to make the device turn on and off repeatedly in the background.
    • Added set_blink_countto set the number of times to blink the device
    • Added wait which blocks until background blinking process is done

  • LED changes:

    • pin is now u8
    • Added active_high: When True, the value property is True when the device's pin is high. When False the value property is True when the device's pin is low (i.e. the value is inverted).
    • Added set_active_high to set the state for active_high
    • blink now takes f32 for on_time and off_time.
    • Added set_blink_countto set the number of times to blink the device
    • Added wait which blocks until background blinking process is done
    • Added is_lit which returns True if the device is currently active and False otherwise.

  • Buzzer changes:

    • pin is now u8
    • Added active_high: When True, the value property is True when the device's pin is high. When False the value property is True when the device's pin is low (i.e. the value is inverted).
    • Added set_active_high to set the state for active_high
    • Added beep to make the device turn on and off repeatedly in the background.
    • Added set_beep_countto set the number of times to beep the device
    • Added wait which blocks until background beeping process is done
    • Removed blink method

  • Motor changes:

    • forward_pin and backward_pinare now u8
    • Added set_speed method: Use set_speed to change the speed at which motors should turn. Can be any value between 0.0 and the default 1.0 (maximum speed)

• device

  • Renamed GPIODevice to GpioDevice
