ESP32 Crash Data Recorder
The ESP32 Crash Data Recorder captures and logs system crash information, stack traces, and diagnostic data when the microcontroller encounters a fault or exception. This project demonstrates how to configure the ESP32's built-in crash detection and storage mechanisms to preserve valuable debugging information that would otherwise be lost.
The guide includes a complete parts list, wiring diagram for optional external storage, step-by-step assembly instructions, and firmware code to initialize crash logging, retrieve stored crash data, and format logs for analysis. Builders will learn how to set up persistent storage, configure exception handlers, and access crash reports via serial output or web interface.
