Detailed Description

Quadrature encoder component — Gray code state machine.

Encoder tracks rotational position from A/B quadrature signals. Uses a 16-entry transition table for robust decoding. The encoder's push-button is a separate Button component (composable).

Usage: sbl::components::control::Encoder enc; enc.update(gpio_a, gpio_b); // Feed A/B each tick int32_t d = enc.delta(); // Steps since last check (+CW/-CCW) int32_t pos = enc.position(); // Cumulative position
