C++ library for direct hardware access to the 8254 Programmable Interval Timer on Windows systems.
Provides low-level access to PIT Channel 0 counter registers through direct port I/O using the inpoutx64 driver. Designed for applications requiring precise timing measurements and hardware interaction.
- Direct PIT counter register access (ports 0x40-0x41)
- Thread-safe operations with mutex protection
- RAII wrapper for automatic resource management
- Minimal overhead for timing-critical code
- x64 Windows compatibility
- Windows 7 or newer
- x64 architecture
- inpoutx64.dll in application directory
bool PIT::initialize(); // Load driver and initialize
void PIT::shutdown(); // Cleanup resources
uint16_t PIT::read_counter(); // Read current PIT counter value
bool PIT::is_initialized(); // Check initialization status
