Implementations

impl<P1, P2, P3> TouchSensor<P1, P2, P3> where
    P1: PinId,
    P2: PinId,
    P3: PinId, [src][−]

pub fn new(
    threshold: [u32; 3],
    confidence: u32,
    adc: Adc<Enabled>,
    adc_timer: Ctimer1<Enabled>,
    sample_timer: Ctimer2<Enabled>,
    _charge_pin: Pin<Pio1_16, Special<MATCH_OUTPUT3<Ctimer1<Enabled>>>>,
    buttons: ButtonPins<P1, P2, P3>
) -> Self[src][−]

Threshold is the ADC sample limit where an is considered. Confidence is the number of times the threshold needs to be crossed

impl<P1, P2, P3> TouchSensor<P1, P2, P3> where
    P1: PinId,
    P2: PinId,
    P3: PinId, [src][−]

pub fn enabled(
    self,
    dma: &mut Dma<Enabled>,
    _token: ClocksSupportTouchToken
) -> Self[src][−]

Starts DMA and internal timers to enable touch detection

impl<P1, P2, P3> TouchSensor<P1, P2, P3> where
    P1: PinId,
    P2: PinId,
    P3: PinId, [src][−]

pub fn count(&self, bufsel: u8) -> u32[src][−]

Count how many elements from a source are available Used for debugging

pub fn reset_results(&self, channel: TouchSensorChannel, offset: i32)[src][−]

Used after an edge is detected to prevent the same edge being detected twice

pub fn get_state(
    &self,
    channel: TouchSensorChannel,
    ctype: Compare
) -> TouchResult[src][−]

Use threshold and confidence value to see if indicated state has occured in current buffer

pub fn has_edge(&self, channel: TouchSensorChannel, edge_type: Edge) -> bool[src][−]

Indicate if an edge has occured in current buffer. Does not reset.
