# LilyGo T-Deck Board Support Package (BSP) Component [![Badge](https://components.espressif.com/components/espp/t-deck/badge.svg)](https://components.espressif.com/components/espp/t-deck) The LilyGo T-Deck is a development board for the ESP32-S3 module. It features a touchscreen display, keyboard, trackball, audio, and expansion headers. The `espp::TDeck` component provides a singleton hardware abstraction for initializing the touch, display, keyboard, trackball, audio, and micro-SD card subsystems. ## Supported Features - ST7789 LCD driven through the shared `espp::Spi` + `SpiPanelIo` path - GT911 capacitive touch input with LVGL integration helpers - T-Keyboard input and trackball pointer input - Audio through the [`espp::Audio`](../audio) component, set up with `initialize_audio(AudioConfig)` (`espp::Audio::AppConfig`, started from `default_audio_config()`; each direction can be turned off to save its I2S DMA ring and task): - I2S speaker output (MAX98357A) with software volume / mute control (`play_audio()`, `volume()`, `mute()`, `audio_sample_rate()`) - Dual microphone recording through the ES7210 ADC on its own I2S bus (a 4-slot TDM frame, of which MIC1 and MIC3 are delivered as 16-bit stereo) at its own sample rate (`AudioConfig::recording_sample_rate`), via `start_audio_recording()`, with adjustable analog gain via `microphone_volume()` - `audio()` / `microphone_audio()` return the two `espp::Audio` instances for anything else; the older `initialize_sound()` / `initialize_microphone()` remain as deprecated wrappers - microSD mounting over SDSPI on the shared SPI host - Backlight brightness control and exposed peripheral helpers ## Example The [example](./example) shows how to use the `espp::TDeck` hardware abstraction component to initialize the major subsystems on the LilyGo T-Deck and interact with the display, touch panel, keyboard, trackball, audio path, and optional microSD card.
