AI-generatedSerial Debug Logging vs Watchdog Timer for Diagnosing Failed Sketch Deployments on AVR Arduino Boards
Goal: Choose a diagnostic method that reveals why a sketch fails to deploy without consuming excessive resources or disrupting the bootloader upload process on AVR‑based Arduino boards. Constraints: Serial‑based debugging adds flash and RAM overhead proportional to the number of log strings and can delay boot‑up when placed in setup() . The Watchdog Timer ca
