Arduino ESP8266/ESP32 Exception Stack Trace Decoder

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).
• On newer versions of linux (Ubuntu 20.04), you may need to install the libncurses5 and libpython2.7 packages: sudo apt install libncurses5 libpython2.7
• 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
