# WaveShare ESP32-S3 1.8inch Knob Display / Guition JC3636K518C-I-YR1 - Knob-ESP32S3

> ESPHome configuration for the WaveShare / Guition knob display on an ESP32-S3.

---

## Status

**WIP** — mostly functional, audio still under test.

---

## Features

- ✅ **ST77916 display** — custom external component via MIPI SPI
- ✅ **CST816 touchscreen** — tap, swipe left/right support
- ✅ **Rotary encoder** — custom polling-based component with debouncing, min/max limits, restore modes, clockwise/anticlockwise triggers, and `set_value` action
- ✅ **LVGL UI** — multi-page interface (clock/weather page + media player page)
- ✅ **Media player integration** — track name, artist, album, volume arc, seek via encoder, album art via `online_image`
- ✅ **Battery monitoring** — ADC voltage with calibrated percentage, arc indicator with color coding (green/orange/red)
- ✅ **SD card** — read, write, append, delete, list, format via `sd_mmc_card` (4-bit MMC mode)
- ✅ **Haptic motor (DRV2605)** — LRA motor with effect library, triggered on encoder turns
- ✅ **Backlight control** — PWM dimming with screensaver timeout (LVGL snow effect on sleep)
- 🧪 **Audio and microphone** — experimental, not yet enabled by default

## Known issues

- Audio and microphone code are still experimental / under test — contributions welcome

If you encounter other issues or want to help, please open an issue or a PR.

## Rotary encoder component

The `rotary_encoder_custom` component is a simple polling-based encoder with optimised debouncing. It lives in `components/` and is picked up automatically as an external component.

```yaml
sensor:
  - platform: rotary_encoder_custom
    name: "Rotary Encoder"
    id: rotary_counter
    pin_a: GPIO8
    pin_b: GPIO7
    min_value: 0
    max_value: 100
    restore_mode: RESTORE_DEFAULT_ZERO  # or ALWAYS_ZERO
    publish_initial_value: true
    on_clockwise:
      - logger.log: "CW"
    on_anticlockwise:
      - logger.log: "CCW"
```

Set value programmatically:

```yaml
- sensor.rotary_encoder_custom.set_value:
    id: rotary_counter
    value: 0
```

See [`components/rotary_encoder_custom/README.md`](components/rotary_encoder_custom/README.md) for full documentation.
