## AI overview

The article describes using Wokwi simulation and Warp's AI vision capabilities to diagnose and fix an RGB565 color-mapping bug in a Raylib port for ESP32 devices. It presents screenshot-based visual debugging, rapid iteration, and automated testing as alternatives to repeated testing on physical hardware.
