KernelUNO v1.0

A Unix-like shell and RAM filesystem for Arduino UNO R3. Write files, control GPIO pins, read sensors, and run simple scripts all from the serial terminal.

Commands (26):

• ls
• cd
• pwd
• mkdir
• touch
• cat
• echo
• rm
• info
• pinmode
• write
• read
• gpio
• pwm
• sh
• uptime
• uname
• dmesg
• df
• free
• whoami
• clear
• reboot
• find
• alias
• slots

How It Works

The code manages a virtual filesystem stored in RAM:

• Maximum 10 files/directories
• Max 32 bytes per file content
• 12 character names
• Automatic /home and /dev directories created on boot
• /dev/pin2, /dev/pin3, /dev/pin4 are special files for GPIO

GPIO control uses standard Arduino functions: pinMode(), digitalWrite(), digitalRead(), and analogWrite().

Input is buffered from the serial connection and parsed line-by-line. Commands are case-insensitive.

Planned Features

• EEPROM support
• I2C interface
• Date cmd
• neofetch cmd
