Touch sensor filter configuration

Fields

mode: touch_filter_mode_t

<Set filter mode. The input of the filter is the raw value of touch reading, and the output of the filter is involved in the judgment of the touch state.

debounce_cnt: u32

<Set debounce count, such as n. If the measured values continue to exceed the threshold for n+1 times, the touch sensor state changes. Range: 0 ~ 7

noise_thr: u32

<Noise threshold coefficient. Higher = More noise resistance. The actual noise should be less than (noise coefficient * touch threshold). Range: 0 ~ 3. The coefficient is 0: 4/8; 1: 3/8; 2: 2/8; 3: 1;

jitter_step: u32

<Set jitter filter step size. Range: 0 ~ 15

smh_lvl: touch_smooth_mode_t

<Level of filter applied on the original data against large noise interference.
