PlatformIO firmware for an Arduino Mega (megaatmega2560) controlling a 3-axis (X/Y/Z) stepper-driven mechanical test stage, plus a Python-based PC-side serial interface for driving it.

Where to look

• src/ — firmware source (StepperMotor, MultiAxisStepper, StageController, SerialComms) and stepper_control_test.ino, the entry point wiring these together.
• include/ — headers for the above, plus include/README.md, which documents the serial command protocol used to talk to the board.
• scripts/StageCommandComms.py — Python client implementing that same protocol, for one-off commands or interactive control from a PC. Usage examples are in include/README.md.
• lib/ — private/project-specific libraries (currently empty; see lib/README for the PlatformIO convention).
• test/ — PlatformIO unit tests (see test/README).
• archive/ — earlier non-PlatformIO Arduino and MATLAB code kept for reference.
• platformio.ini — build/board/environment configuration.

Building

Standard PlatformIO workflow (pio run, pio run -t upload) targeting the megaatmega2560 environment defined in platformio.ini.
