## Pull Request: Disable INA226 Current Sensing by Default (Hardware Compatibility)

[tazomatalax]

Summary

This pull request comments out all code related to INA226 current sensing in order to prevent microcontroller lockups caused by a faulty or missing INA226 component. The code remains in place and is clearly commented, so it can be easily re-enabled in the future by simply uncommenting the relevant lines.

Details

• main.cpp
  • All INA226 initialization and runtime code is commented out.
  • The handle_current_sensor() function and its calls are commented out.
  • Forward declarations and related logic are commented out.
• sys_init.h
  • INA226 header include, object instantiation, and calibration defines are commented out.
• README.md
  • Added a section explaining that INA226 current sensing is present but disabled by default.
  • Provided instructions for re-enabling current sensing if hardware is available and working.
  • Clarified that all other features (ADC, RPM, Modbus, etc.) remain fully functional.

Motivation

• Prevents microcontroller lockups on hardware with a faulty or missing INA226.
• Makes it easy for future users to restore current sensing by uncommenting code.
• Documents the change and the reason for it in the README.

How to Re-enable Current Sensing

1. Uncomment all INA226-related code in main.cpp and sys_init.h.
2. Ensure the INA226 is present and connected correctly on your hardware.
3. Rebuild and upload the firmware.
