Arduino Nano/Uno/Mega is not detected¶
When you run
arduino-cli board list, your board doesn't show up. Possible causes:
- Your board is a cheaper derivative, or
- It's a board, such the classic Nano, that uses a USB to serial converter like FTDI FT232 or CH340. These chips always report the same USB VID/PID to the operating system, so the only thing we know is that the board mounts that specific USB2Serial chip, but we don’t know which board that chip is on.
What's the FQBN string?¶
For a deeper understanding of how FQBN works, you should understand the Arduino platform specification.
How to set multiple board options?¶
Additional board options have to be separated by commas (instead of colon):
$ arduino-cli compile --fqbn "esp8266:esp8266:generic:xtal=160,baud=57600" TestSketch
Where is the Serial Monitor?¶
The serial monitor is available through the monitor command. By the way, the functionality provided by this command is very limited and you may want to look for other tools if you need more advanced functionality.
How to change monitor configuration?¶
Configuration parameters of the monitor can be obtained by executing the following command:
$ arduino-cli monitor -p <port> --describe
These parameters can be modified by passing a list of
<key>=<desiredValue> pairs to the
--config flag. For example,
when using a serial port, the monitor baud rate can be set to 4800 with the following command:
$ arduino-cli monitor -p <port> --config baudrate=4800
