ScreenX

ScreenX is a DIY telemetry display for the Moza ES Lite wheel. It streams Assetto Corsa data over WiFi to an ESP32 + 2.08" OLED mounted on your wheel, powered by a desktop companion app.

Features

• Real-time telemetry (speed, RPM, gear, temps, etc.)
• One-click flashing and WiFi setup from the companion app
• Wireless ESP32 connection (no extra wires to the PC)
• Optional PCB workflow (coming soon)

Requirements

Hardware

• Seeed Studio XIAO ESP32 (C6 recommended; C3/S3 supported)
• 2.08" 256x64 SPI OLED (7-pin)
• Jumper wires

Software

• Windows 10/11
  • Linux is NOT supported because of Asseto Corsa not running natively on linux and needing a emulator to run, thus making it so the companion app cannot access the AC shared memory.
• Python 3.9+ (only if running from source)
• Assetto Corsa

Quick Start (Companion App)

1. Download the latest release from the GitHub releases page.
2. Run companion.exe.
3. Follow the in-app onboarding (detect device, flash firmware, send WiFi).
4. Enter the ESP32 IP shown on the display in the Dashboard tab.

Firmware

If you are building or flashing manually, you can use firmware.ino or the prebuilt firmware.bin. The companion app can flash .bin files directly.

Docs

See the HTML docs in docs/, or on the website to the right of this repo, for full wiring, setup, and troubleshooting.

Ai usage disclosure

AI was used in the following ways to assist with this project:

• Code auto completions
• Debugging help (Sparsely)
• Cleaning up the ESP32 gui after I made the original version
• Cleaning messy code and some frontend gui
• Parts of documentation, I have since verified all information inside the docs is correct
