ESP32-S3 Camera Firmware

A camera firmware project for the Seeed Studio XIAO ESP32-S3 development board with battery management, BLE connectivity, and camera functionality.

Hardware Requirements

• Seeed Studio XIAO ESP32 S3 Sense
• Compatible Li-ion battery (optional)
• Camera module (OV2640/OV5640)

Features

• Camera Support: Image capture and streaming
• Battery Management: Voltage monitoring and charge level detection
• Power Management: USB charging detection and power optimization
• BLE Connectivity: Bluetooth Low Energy for device communication
• LED Management: Status indication and user feedback
• Hardware Abstraction: Centralized pin definitions and constants

Getting Started

Hardware Setup

1. Connect your XIAO ESP32-S3 board
2. Optional: Connect a compatible Li-ion battery
3. Ensure camera module is properly connected

Software Setup

1. Install Arduino IDE or arduino-cli

2. Add ESP32 board package:

   arduino-cli config add board_manager.additional_urls https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json
   arduino-cli core install esp32:[email protected]

3. Compile and upload:

   cd firmware
   arduino-cli compile --build-path ../build --output-dir ../dist -e -u -p COM5 -b esp32:esp32:XIAO_ESP32S3:PSRAM=opi
