SkyLogic AeroAlign - Implementation Status

Date: 2026-03-11
State: AeroAlign working, CoG integration base prepared

Repository Status

The project now has two layers:

1. working AeroAlign firmware and UI for IMU-based angle measurement
2. shared protocol and documentation base for the upcoming CoG scale extension

Implemented

Firmware

• Master firmware builds for esp32-c3 and esp32-s3
• IMU slave firmware builds for the current slave environments, including S3
• Master and Slave use the same direct MPU6050 register access approach
• shared ESP-NOW packet format supports device typing:
  • IMU
  • CoG Scale
  • Hybrid
• Master data model and UI can already represent CoG-style telemetry fields

UI

• current tabs remain angle-focused: Sensors, Differential, System
• mixed-device node cards are supported
• differential selection excludes CoG-only nodes
• Master battery display is hidden when the ADC path is not available

Documentation

• README rewritten for combined AeroAlign + CoG direction
• IMU wiring brought to current C3/S3 and battery-monitoring behavior
• new CoG wiring guide added
• BOM converted from placeholder marketplace list to current component overview
• CAD readme updated to include planned CoG fixtures

Current Hardware Documentation

• README.md
• sensor_node_wiring.md
• cog_scale_wiring.md
• bom.csv
• hardware/cad/README.md
• AEROALIGN_COG_INTEGRATION.md

What Works Right Now

• Master AP + web UI
• IMU node discovery over ESP-NOW
• calibration and differential measurement for angle nodes
• S3-safe IMU access path
• optional battery reporting on Master hardware where ADC is not wired

What Is Not Finished Yet

• dedicated firmware/cog_slave
• HX711 integration
• tare and scale calibration persistence
• model profiles for support spacing and target CoG
• dedicated CoG workflow in the UI

Recommended Next Step

Implement the actual CoG node firmware next, because the protocol, Master-side data path and baseline documentation are now in place.
