Struct kiibohd_hall_effect_keyscanning::Matrix

pub struct Matrix<C: OutputPin, const CSIZE: usize, const MSIZE: usize, const INVERT_STROBE: bool> { /* private fields */ }

Handles strobing the Hall Effect sensor matrix ADC reading is handled separately as the current embedded-hal doesn’t work well across oneshot, interrupt based and DMA ADC read methods. (usually requires quite a bit of MCU specific setup as well)

const CSIZE: usize = 18; // Number of columns
const RSIZE: usize = 6; // Number of rows
const MSIZE: usize = RSIZE * CSIZE; // Total matrix size
const INVERT_STROBE: bool = true; // P-Channel MOSFETs have an inverted strobe
type Matrix = kiibohd_hall_effect_keyscanning::Matrix<PioX<Output<PushPull>>, CSIZE, MSIZE, INVERT_STROBE>; // atsam4-hal

Implementations

impl<C: OutputPin, const CSIZE: usize, const MSIZE: usize, const INVERT_STROBE: bool> Matrix<C, CSIZE, MSIZE, INVERT_STROBE>

pub fn new( cols: [C; CSIZE], mode: SensorMode, activation: i16, deactivation: i16 ) -> Result<Self, SensorError>

pub fn clear<'a, E: 'a>(&'a mut self) -> Result<(), E>where C: OutputPin<Error = E>,

Clears strobes Resets strobe counter to the last element (so next_strobe starts at 0)

pub fn next_strobe<'a, E: 'a>(&'a mut self) -> Result<usize, E>where C: OutputPin<Error = E>,

Next strobe

pub fn strobe(&self) -> usize

Current strobe

pub fn record<const IDLE_LIMIT: usize>( &mut self, index: usize, value: u16 ) -> Result<Option<&SenseData>, SensorError>

Record ADC Hall Effect reading for the given the current row/sense index The sense index is usually 0-5, though it depends on the typical setup IDLE_LIMIT - Number of samples before considering the sensor idle (within the configured range)

pub fn state(&self, index: usize) -> Option<Result<&SenseData, SensorError>>

Return current SenseData for a given index
