like... you're opening a lil chat window with your microcontroller. iconic behavior honestly. 👑

---

🌸 SYNOPSIS 🌸

arduino-cli monitor [flags]

that's it. that's the whole vibe. flags go brrr. ✨

🦋 DESCRIPTION 🦋

Open a communication port with a board.

fr fr, that's the entire description. the manpage said what it said and it said it in one sentence. main character energy — no filler, all substance. 💅

🎀 OPTIONS 🎀

every single flag, bestie, no skipping, we don't do that here:

• --board-options=[] — List of board options separated by commas. Or can be used multiple times for multiple options. (yes queen, either style works, you do you 💜)
• -c, --config=[] — Configure communication port settings. The format is =[,=]...
• --describe[=false] — Show all the settings of the communication port. give me the whole lore pls 🍓
• --discovery-timeout=1s — Max time to wait for port discovery, e.g.: 30s, 1m
• -b, --fqbn="" — Fully Qualified Board Name, e.g.: arduino:avr:uno
• -h, --help[=false] — help for monitor
• -p, --port="" — Upload port address, e.g.: COM3 or /dev/ttyACM2
• -m, --profile="" — Sketch profile to use
• -l, --protocol="" — Upload port protocol, e.g: serial
• -q, --quiet[=false] — Run in silent mode, show only monitor input and output. 🤫
• --raw[=false] — Set terminal in raw mode (unbuffered).
• --timestamp[=false] — Timestamp each incoming line. ⏰

🧚 OPTIONS INHERITED FROM PARENT COMMANDS 🧚

these ones you got from the family, not from monitor itself, but they still ride with you everywhere:

• --additional-urls=[] — Comma-separated list of additional URLs for the Boards Manager.
• --config-dir="" — Sets the default data directory (Arduino CLI will look for configuration file in this directory).
• --config-file="" — The custom config file (if not specified the default will be used).
• --json[=false] — Print the output in JSON format.
• --log[=false] — Print the logs on the standard output.
• --log-file="" — Path to the file where logs will be written.
• --log-format="text" — The output format for the logs, can be: text, json
• --log-level="info" — Messages with this level and above will be logged. Valid levels are: trace, debug, info, warn, error, fatal, panic
• --no-color[=false] — Disable colored output. 😭 (why would you, but okay)

🔥 EXAMPLE 🔥

look at her go, she's serving:

debian/build/bin/arduino-cli monitor -p /dev/ttyACM0
debian/build/bin/arduino-cli monitor -p /dev/ttyACM0 -b arduino:avr:uno
debian/build/bin/arduino-cli monitor -p /dev/ttyACM0 --config 115200
debian/build/bin/arduino-cli monitor -p /dev/ttyACM0 --describe

ate. no crumbs. 🌈
