- **HarmonyOS** (Huawei, Honor)

### Embedded / IoT
- **Raspberry Pi** (Zero, 3, 4, 5) - Linux with LCD/HDMI display
- **Orange Pi** - Budget Raspberry alternative with NPU
- **Banana Pi** - ARM boards with display
- **BeagleBone** - Industrial IoT
- **Arduino** (with ESP32/ESP8266) - OLED/LCD display + WiFi
- **ESP32** - TFT/OLED displays
- **Rock Pi** - RK3399/RK3588 boards
- **NVIDIA Jetson** - Edge AI with display
- **LattePanda** - x86 embedded
- **ODROID** - Hardkernel boards

### Supported Displays
- LCD Character (16x2, 20x4)
- OLED (128x64, 128x32)
- TFT/IPS (320x240, 480x320, 800x480)
- E-ink/E-paper
- HDMI (any resolution)

## Installation Levels

| Level | Requirements | What it does |
|-------|-------------|--------------|
| **1** | ADB only | Removes bloatware, installs BotDevice as app |
| **2** | Root + Magisk | GB boot animation, BotDevice as system app |
| **3** | Unlocked bootloader | Replaces entire Android with BotDevice |

## Quick Start

```bash
cd botdevice/rom
./install.sh
```

The installer automatically detects the device and shows available options.

## Prerequisites

### To compile BotDevice App

```bash
# Rust and Android targets
rustup target add aarch64-linux-android armv7-linux-androideabi

# Android SDK and NDK
export ANDROID_HOME=$HOME/Android/Sdk
export NDK_HOME=$ANDROID_HOME/ndk/25.2.9519653

# Tauri CLI
cargo install tauri-cli
```

### To install on devices

```bash
# ADB
sudo apt install adb

# To generate icons/boot animation
sudo apt install librsvg2-bin imagemagick
```

## Building

```bash
cd botdevice

# Generate icons
./scripts/generate-icons.sh

# Initialize Android project
cargo tauri android init

# Build APK
cargo tauri android build --release
```

## Installation

### Quick Method (Interactive)

```bash
cd botdevice/rom
chmod +x install.sh
./install.sh
```

### Manual Method

#### Level 1: Debloat + App (No Root)

```bash
# Connect device via USB (debug enabled)
cd botdevice/rom/scripts
./debloat.sh

# Install APK
adb install ../gen/android/app/build/outputs/apk/release/app-release.apk

# Set as launcher: Home → BotDevice → Always
```

#### Level 2: Magisk Module (With Root)

```bash
# Generate module
cd botdevice/rom/scripts
./build-magisk-module.sh

# Copy to device
adb push botdevice-magisk-v1.0.zip /sdcard/

adb logcat -s BotDevice:*
```

## Embedded Interface (LCD/Keyboard)

For devices with limited resources, use the embedded interface at `botui/ui/embedded/`:

chromium-browser --kiosk --app=http://localhost:8088/embedded/

# ESP32 with TFT display (via WebView)
# Configure BOTSERVER_URL in firmware

# Character terminal mode
# Use botui/ui/embedded/ with CONFIG.maxMsgLen adjusted
```
