Show HN: C++ library for reading MacBook lid angle sensor data

Summary

MacBook Lid Angle Sensor C++ Library A C++ library for reading MacBook lid angle sensor data, based on reverse engineering of HID device specifications. Features 🔍 Direct access to MacBook's built-in lid angle sensor 📏 Real-time precise angle measurements (0-360 degree range) ⚡ High-performance C++ implementation with modern C++14 standard support 🛡️ Comprehensive exception handling mechanism 🔧 Clean and easy-to-use API interface 📦 CMake build system support Device Compatibility Supported Devices MacBook Pro 16-inch (2019) and newer models MacBook Pro M2/M3/M4 series Known Incompatible Devices M1 MacBook Air/Pro (sensor access restricted) Technical Specifications Device identification: Apple VID=0x05AC, PID=0x8104 HID usage: Sensor page (0x0020), Orientation usage (0x008A) Data format: 16-bit angle value with 0.01-degree precision Data range: 0-360 degrees Quick Start System Requirements macOS 10.15 or later Xcode Command Line Tools CMake 3.15 or later Build and Installation # Clone the repository git clone < repository-url > cd mac-angle # Create build directory mkdir build && cd build # Configure build cmake .. # Compile make # Run example program ./lid_angle_example Basic Usage # include " angle.h " # include < iostream > using namespace MacBookLidAngle ; int main () { try { // Create sensor instance LidAngleSensor sensor; // Check if sensor is available if (sensor. isAvailable ()) { // Read current angle double angle = sensor. readAngle (); std::cout << " Current lid angle: " << angle << " ° " << std::endl; } } catch ( const SensorNotSupportedException& e) { std::cerr << " Device not supported: " << e. what () << std::endl; } catch ( const SensorInitializationException& e) { std::cerr << " Initialization failed: " << e. what () << std::endl; } catch ( const SensorReadException& e) { std::cerr << " Read failed: " << e. what () << std::endl; } return 0 ; } Continuous Monitoring # include " angle.h " # include < iostream > # include < chrono > # include < thread > ...
