ArduinoCrashMonitor | Event-driven crash monitor service

ArduinoCrashMonitor is a C++ library typically used in Internet of Things (IoT), Arduino applications. ArduinoCrashMonitor has no bugs, it has no vulnerabilities, it has a Strong Copyleft License and it has low support. You can download it from GitHub.

This library takes advantage of the Arduino's watchdog capability to trigger an interrupt in the event that the Arduino sketch (firmware) becomes unresponsive due to a crash (divide by zero, Ethernet shield fails to initialize, etc). The general idea behind this is: during each iteration of loop(), CrashMonitor's iAmAlive() method should be called to signal to CrashMonitor that the sketch is still running. If CrashMonitor does not receive the iAmAlive() signal before the end of the timeout, then an interrupt is triggered. The interrupt will call a routine that will generate a small report that contains the address of the last instruction the Arduino attempt to execute (and optionally some user data) and write the report to EEPROM. You can also have the interrupt call a user-specified callback. Once the report is written to EEPROM, the MCU will be restarted or will hang indefinitely until manually reset. You can then use the dump() method to load the crash reports and dump them to a Serial port.
