kiibohd-hall-effect-keyscanning

Keyscanning embedded-hal driver for kiibohd-hall-effect. Can be used with single-shot, interrupt or DMA-connected ADC drivers.

Usage

```rust const ADCSAMPLES: usize = 1; const RSIZE: usize = 6; // Matrix rows const CSIZE: usize = 12; // Matrix columns const MSIZE: usize = RSIZE * CSIZE; // Total matrix size type Matrix = kiibohdhalleffectkeyscanning::Matrix>, CSIZE, MSIZE>;

let mut matrix = Matrix::new(cols).unwrap(); matrix.next_strobe().unwrap(); // Strobe first column

// Retrieve adc sample and key index let sample = readadc(); let index = determinekey_index();

// Store the sample value at the specified index // ADC_SAMPLES specifies how many samples are needed (averaged) until a processed sense value is returned match matrix.record::(index, sample) { Ok(val) => { // If data bucket has accumulated enough samples, pass to the next stage if let Some(sense) = val { // Processed ADC data } } Err(e) => { // Usually this is an index error defmt::error!("Sample record failed ({}, {}, {}):{} -> {}", i, strobe, index, sample, e); }

```
