📷 cameraDisplay

A portable USB camera display solution developed under Arduino IDE 2.3.7. This project allows you to plug a UVC camera into an ESP32-S2 and display the live feed on a small TFT screen.

📺 Demo & Preview

Check out the 3D models on my Thingiverse page. The current design can continually run on battery for over 1 hour. Ideal for USB cameras with low resolutions. i.e.,a thermal camera like Haikang 4117 as per demo

⚠️ Important Installation Steps

Important

You MUST replace the original configuration file to enable the USB stream:

Replace: ~\Arduino\libraries\ESP32_USB_STREAM\src\original\include\arduino_config.h With: The arduino_config.h provided in this repository.

Current Limitations:

• Currently only supports UVC MJPEG 320x240 format.

🎯 Project Goals

• Battery-powered portable screen.
• Plug-and-play USB camera image display.

📝 TODO List

• OTA: Support Over-the-Air updates.
• Wireless: Stream in/out via Wi-Fi or ESP-NOW.
• Storage: Add TF card support for recording and playback.
