This tutorial introduces how to use the example projects provided on Wireless-Tag's GitHub for the WT9932P4-MINI-A1 development board, including MIPI-DSI display, camera, and more.
- 🎯 Smartphone-style UI — based on the ESP-Brookesia framework
- 📱 Multiple applications — calculator, camera app
- 🤖 AI vision features — face detection, pedestrian detection
- 🖥️ High-definition display — supports MIPI-DSI interface screens
- 📷 Camera support — 1280×960 resolution camera
1. Hardware Preparation
- Development Board: WT9932P4-MINI-A1
