The full story
A diagnostic tool for the ESP32-2432S028 "Cheap Yellow Display" board. It works out whether the screen uses an ILI9341 or ST7789, walks you through touch calibration and orientation, tests the SD card, RGB LED, speaker, Wi-Fi and more, and saves a report to the SD card.
It was built with Claude over a few days of back-and-forth.
