Arduino ESP8266/ESP32 Exception Stack Trace Decoder Build Status

Arduino plugin which lets you get a more meaningful explanation of the stack traces you get on ESP8266/ESP32.

Installation

  • Make sure you use one of the supported versions of Arduino IDE and have ESP8266/ESP32 core installed.
  • Download the tool archive from releases page.
  • In your Arduino sketchbook directory, create tools directory if it doesn't exist yet.
  • Unpack the tool into tools directory (the path will look like <home_dir>/Arduino/tools/EspExceptionDecoder/tool/EspExceptionDecoder.jar).
  • Restart Arduino IDE.

Usage

  • Open a sketch and build it.
  • Upload the sketch and monitor the Serial port for Exceptions
  • When you get an Exception, open Tools > ESP Exception Decoder menu item. This will open a new window.
  • Paste the stack trace into the window's top pane and the result will show in the bottom.
  • Every time you enter new address or stack trace, the results will refresh

Command line version

If you are searching for a command line version, look at [EspStackTraceDecoder] (https://github.com/littleyoda/EspStackTraceDecoder). EspStackTraceDecoder is based on the EspExceptionDecoder, but was completely rewritten for the command line usage.
