QWERTY Keyboard Tester

The tool performs hardware-level validation of a standard QWERTY keyboard by capturing keystroke events and reporting per-key status. It benefits hardware engineers, QA teams, and repair technicians who require objective keystroke verification during development, manufacturing, or post-service diagnostics. It provides a clear pass/fail determination and per-key detail without reliance on software UI tests.
Conceptually, the system maps hardware scan codes to a standard key set, streams events in real time, and maintains a per-key state for each key. It detects stuck keys, ghosting, and mismapped rows by comparing observed activity against a defined layout. The result is a structured report that can be archived for traceability.
Core features include real-time event capture, ANSI QWERTY layout support, per-key status reporting, and exportable results. Optional capabilities cover alternate layouts, custom key-code maps, adjustable debounce thresholds, and JSON/CSV exports for defect tracking. The tool suits manufacturing test benches, repair workflows, and remote QA labs.
This approach yields objective metrics, reduces reliance on manual checks, and accelerates the validation cycle for keyboards before release or after repair, ensuring key fidelity and layout correctness.
