pio-device: Start an interactive device monitor and listen to a specific port.

$ pio device monitor --port ${-dev-ttyUSBX}

try on your machine

This command is used to start the device monitor in PlatformIO, a development environment for embedded systems. The device monitor allows you to monitor the output from a connected device (such as a microcontroller) and interact with it through the serial port.

Let's break down the command:

pio device monitor: This is the main command to start the device monitor in PlatformIO.
--port ${-dev-ttyUSBX}: This specifies the serial port that the device is connected to. The ${-dev-ttyUSBX} is a placeholder for the actual port name, where X represents a number (e.g., 0, 1, 2, etc.). The port name format ttyUSBX is typically used in Linux systems for USB-to-serial converters. You need to replace ${-dev-ttyUSBX} with the actual port name of your device.

By running this command with the correct port name, the device monitor will launch and display the output from your device in the terminal. You can also send commands or data to the device through the same terminal interface.
