Initial release v1.1.0 — ESP32 automated telescope flat panel
Firmware (Arduino Nano ESP32 / PlatformIO): - Native ASCOM Alpaca CoverCalibrator REST API on port 11111 - Alnitak serial protocol on USB at 9600 baud (simultaneous with WiFi) - MG995 servo cover mechanism with non-blocking state machine (D9) - LED brightness PWM via IRLZ44N MOSFET, LEDC channel 0 (D3) - 12V dew heater PWM via IRLZ44N MOSFET, LEDC channel 1 (D5) - mDNS + UDP Alpaca discovery, WiFi watchdog reconnect - SERIAL_DEBUG flag to silence debug output in USB-only mode INDI driver (C++ / libcurl / nlohmann-json): - WiFi mode: HTTP Alpaca via libcurl - USB mode: Alnitak serial via POSIX termios - LightBoxInterface + DustCapInterface + dew heater number property Python controller (PyQt6): - Dark-themed desktop app for direct manual control - AlpacaBackend (requests) + AlnitakBackend (pyserial) - PollWorker QThread; cover, brightness, dew heater panels - QSettings persistence; auto serial port discovery Docs: - system-diagram.svg, wiring-diagram.svg (browser-renderable SVG) - BUILD_NOTES.md with BOM, LM2596 calibration, power-on checklist - WIRING.md quick-reference, README.md, CHANGELOG.md
