+# ZeroClaw ESP32 UI Firmware
+
+Slint-based graphical interface for ZeroClaw AI assistant on ESP32.
+
+## Features
+
+- **Modern UI**: Declarative interface built with Slint UI framework
+- **Touch Support**: Compatible with resistive (XPT2046) and capacitive (FT6X36) touch panels
+- **Display Options**: Support for ST7789, ILI9341, and SSD1306 displays
+- **Connectivity**: WiFi and Bluetooth Low Energy support
+- **Memory Efficient**: Optimized for ESP32's limited RAM (~520KB)
+
+## Hardware Requirements
+
+### Recommended: ESP32-S3
+- **SoC**: ESP32-S3 (Xtensa LX7 dual-core, 240MHz)
+- **RAM**: 512KB SRAM + 8MB PSRAM (optional but recommended)
+- **Display**: 2.8" 320x240 TFT LCD (ST7789 or ILI9341)
+- **Touch**: XPT2046 resistive or FT6X36 capacitive
+- **Storage**: 4MB+ Flash
+
+### Alternative: ESP32-C3
+- **SoC**: ESP32-C3 (RISC-V single-core, 160MHz)
+- **RAM**: 400KB SRAM
+- **Display**: 1.14" 135x240 TFT (ST7789)
+- **Note**: Limited to simpler UI due to RAM constraints
+
+## Project Structure
+
+```
+firmware/zeroclaw-esp32-ui/
+├── Cargo.toml          # Rust dependencies
+├── build.rs            # Build script for Slint compilation
+├── .cargo/
+│   └── config.toml     # Cross-compilation settings
+├── ui/
+│   └── main.slint      # Slint UI definition
+└── src/
+    └── main.rs         # Application entry point
+```
+
+## Prerequisites
+
+1. **Rust toolchain with ESP32 support**:
+   ```bash
+   cargo install espup
+   espup install
+   source ~/export-esp.sh
+   ```
+
+2. **Additional tools**:
+   ```bash
+   cargo install espflash cargo-espflash
+   ```
+
+3. **Hardware setup**:
+   - Connect display to SPI pins (see pin configuration below)
+   - Ensure proper power supply (3.3V logic level)
+
+## Pin Configuration
+
+Default pin mapping for ESP32-S3 with ST7789 display and FT6X36 capacitive touch:
+
+### Display (SPI)
+
+| Function | GPIO Pin | Description |
+|----------|---------|-------------|
+| SPI SCK  | GPIO 6   | SPI Clock |
+| SPI MOSI | GPIO 7   | SPI Data Out |
+| SPI MISO | GPIO 8   | SPI Data In (optional) |
+| SPI CS   | GPIO 10  | Chip Select |
+| DC       | GPIO 4   | Data/Command |
+| RST      | GPIO 3   | Reset |
+| Backlight| GPIO 5   | Display backlight |
+
+### Touch Controller (I2C)
+
+| Function | GPIO Pin | Description |
+|----------|---------|-------------|
+| I2C SDA | GPIO 1   | I2C Data |
+| I2C SCL | GPIO 2   | I2C Clock |
+| INT     | GPIO 11  | Touch interrupt |
+
+### Hardware Connections
+
+```
+ESP32-S3              ST7789 Display        FT6X36 Touch
+-----------           ---------------        -------------
+GPIO 6  ──────────►  SCK
+GPIO 7  ──────────►  MOSI
+GPIO 10 ──────────►  CS
+GPIO 4  ──────────►  DC
+GPIO 3  ──────────►  RST
+GPIO 5  ──────────►  BACKLIGHT (via resistor)
+
+GPIO 1  ──────────►  SDA
+GPIO 2  ──────────►  SCL
+GPIO 11 ◄──────────  INT
+```
+
+**Note**: Use 3.3V for power. ST7789 typically requires 3.3V logic level.
+
+## Building
+
+### Standard build for ESP32-S3:
+```bash
+cd firmware/zeroclaw-esp32-ui
+cargo build --release
+```
+
+### Flash to device:
+```bash
+cargo espflash flash --release --monitor
+```
+
+### Build for ESP32-C3 (RISC-V):
+```bash
+rustup target add riscv32imc-esp-espidf
+cargo build --release --target riscv32imc-esp-espidf
+```
+
+### Feature flags:
+```bash
+# Use ILI9341 display instead of ST7789
+cargo build --release --features display-ili9341
+
+# Enable WiFi support
+cargo build --release --features wifi
+
+# Enable touch support
+cargo build --release --features touch-xpt2046
+```
+
+## UI Design
+
+The interface is defined in `ui/main.slint` with the following components:
+
+- **StatusBar**: Shows connection status and app title
+- **MessageList**: Displays conversation history
+- **InputBar**: Text input with send button
+- **MainWindow**: Root container with vertical layout
+
+### Customizing the UI
+
+Edit `ui/main.slint` and rebuild:
+```bash
+cargo build --release
+```
+
+The build script automatically compiles Slint files.
+
+## Memory Optimization
+
+For ESP32 (non-S3) with limited RAM:
+
+1. Reduce display buffer size in `main.rs`:
+   ```rust
+   const DISPLAY_WIDTH: usize = 240;
+   const DISPLAY_HEIGHT: usize = 135;
+   ```
+
+2. Use smaller font sizes in Slint UI
+
+3. Enable release optimizations (already in Cargo.toml):
+   - `opt-level = "s"` (optimize for size)
+   - `lto = true` (link-time optimization)
+
+## Troubleshooting
+
+### Display shows garbage
+- Check SPI connections and pin mapping
+- Verify display orientation in `Builder::with_orientation()`
+- Try different baud rates (26MHz is default)
+
+### Out of memory
+- Reduce Slint window size
+- Disable unused features
+- Consider ESP32-S3 with PSRAM
+
+### Touch not working
+- Verify touch controller is properly wired
+- Check I2C/SPI address configuration
+- Ensure interrupt pin is correctly connected
