I2CStepper/README.md

I2CStepper

Control a stepper motor via I2C using a master-slave microcontroller setup.

Features

• Control stepper motors (e.g., TMC2209 + NEMA 17) over I2C
• Change slave I2C address at runtime (persistent in EEPROM)
• Scan for available I2C devices
• Simple API for master and slave
• Example code included

Hardware Requirements

• Two Arduino-compatible microcontrollers (e.g., Uno, ESP32, etc.)
• TMC2209 stepper driver or similar (STEP/DIR interface)
• NEMA 17 or compatible stepper motor
• I2C wiring between master and slave

Installation

1. Download or clone this repository.
2. Copy the folder to your Arduino libraries directory.
3. Open Arduino IDE and include I2CStepper.h in your project.
