monitor.sh

#!/usr/bin/env bash
# Open serial monitor for the UnitCamS3-5MP.
# Usage: ./monitor.sh [port]
#   port: optional, e.g. /dev/cu.usbmodem1101 (macOS) or /dev/ttyACM0 (Linux)
# Exit with Ctrl+]
#
# Works for both IDF v5 and v6 builds — idf.py monitor decodes crash addresses
# from the ELF file's DWARF info, so the IDF version used here does not matter.
