[][src]Struct AT42QT2120::At42qt2120

pub struct At42qt2120<I2C> { /* fields omitted */ }

Driver for the AT42QT2120

Methods

impl<I2C, E> At42qt2120<I2C> where
    I2C: WriteRead<Error = E> + Write<Error = E>, 
[src]

pub fn new(i2c: I2C) -> Self[src]

initialize the AT42QT2120 driver. No configuration is made at this point and defaults are in place.

pub fn setup(&mut self) -> Result<(), Error<E>>[src]

Setup the device, currently just checks the chip ID.

pub fn setup_slider(
    &mut self,
    slider: bool,
    enabled: bool
) -> Result<(), Error<E>>
[src]

Setup the slider settings, slider is false for slider, true for wheel.

pub fn setup_key(
    &mut self,
    key: u8,
    threshold: u8,
    enabled: bool
) -> Result<(), Error<E>>
[src]

Setup a key. Keys can be enabled or disabled, the lower the threshold, the more sensitive the key. Settings here also count for the slider/wheel.

pub fn keys_pressed(&mut self) -> Result<bool, Error<E>>[src]

Checks if any keys are pressed.

pub fn slider_pressed(&mut self) -> Result<bool, Error<E>>[src]

Checks if the slider is pressed.

pub fn read_status(&mut self) -> Result<u8, Error<E>>[src]

read the raw detection status register

pub fn read_slider(&mut self) -> Result<u8, Error<E>>[src]

read the slider position. Only valid when the slider is pressed.

pub fn read_key_value(&mut self, key: u8) -> Result<u16, E>[src]

read the raw 16 bit key signal

pub fn read_keys(&mut self) -> Result<u16, Error<E>>[src]

read all key values. bit 0 is for key 0, bit 1 for key 1 and so forth

pub fn read_key(&mut self, key: u8) -> Result<bool, Error<E>>[src]

read if a key is pressed
