Running Containers 

# Run container interactively
docker run -it <image_name> /bin/bash

# Run container in background
docker run -d <image_name>

# Run with port mapping

Arduino CLI Commands

Board Management 

# Update board package index
arduino-cli core update-index

# Install board package (e.g., ESP32)
arduino-cli core install esp32:esp32

# List installed boards
arduino-cli core list

# List available boards
arduino-cli board listall

# Search for boards
arduino-cli core search <board_name>
Enter fullscreen mode Exit fullscreen mode

Library Management

Enter fullscreen mode Exit fullscreen mode

Compilation and Upload 

# Compile sketch
arduino-cli compile --fqbn <board_fqbn> <sketch_path>

# Upload to board
arduino-cli upload -p <port> --fqbn <board_fqbn> <sketch_path>

# Compile and upload in one command
arduino-cli compile --upload -p <port> --fqbn <board_fqbn> <sketch_path>

# Set upload speed (in sketch or command)
arduino-cli upload -p <port> --fqbn <board_fqbn> <sketch_path> --upload-field upload.speed=921600
Enter fullscreen mode Exit fullscreen mode

Board Detection and Port Management

# Connect with different baud rates
picocom -b 9600 /dev/ttyUSB0
picocom -b 57600 /dev/ttyUSB0
picocom -b 921600 /dev/ttyUSB0

# Exit picocom: Ctrl+A then Ctrl+X

# List available serial ports
ls /dev/tty*
# or
dmesg | grep tty
Enter fullscreen mode Exit fullscreen mode
