Enum InputCaps 

Source 
pub enum InputCaps {
    Keypad {
        buttons: u8,
    },
    Pointer {
        width: u16,
        height: u16,
    },
}
Expand description

What input model a board exposes, so a consumer can install the matching LVGL indev (keypad vs pointer) instead of assuming three buttons (#32 I2). This is a capability descriptor only — it carries no app vocabulary (no nav/semantic meaning); see buttons::ButtonEvent for the I1 event contract and input_caps to query the running board.

Variants§

§

Keypad

Discrete buttons (Fire27: three front-panel buttons). Drive an LVGL KEYPAD/ENCODER indev from the buttons::ButtonEvent stream.

Fields

§buttons: u8
§

Pointer

A touch panel of the given pixel size (CoreS3: FT6336U). Drive an LVGL POINTER indev from driver::ft6336u::read_touch, or the zone-emulated touch_buttons::TouchButtons keypad stream.

Fields

§width: u16
§height: u16
