HUD

This project receives lane deviation and inter-vehicle distance data from a Raspberry Pi, displays the information on an ESP32-based display module, and implements a HUD (Head-Up Display) using a combiner method.

Key Features

• Real-time visualization of lane deviation and following distance
• Display output using ESP32 and LVGL
• HUD implementation via combiner reflection
• Touch-based UI with calibration functionality

HW

• Waveshare ESP32-S3 2.41inch AMOLED Touch Display
  • MCU : ESP32-S3
  • Driver IC : RM690B0
  • Touch IC : FT6336

SW

• Squareline Studio : 1.5.3
• LVGL : 8.3.11
• IDE : PlatformIO

System Overview

HUD usage example
