Davis Logic V2 Module 068: Zero-Crossing Frequency Tracker and Signal Filter Core

Module 068 from the Davis Logic V2 architecture provides a unified digital signal conditioning pipeline for embedded systems. Built entirely in freestanding, zero-heap C++11, it resolves signal imperfections like noise, drift, and deadband non-linearities using fixed-point math. The 4.9 KB text file, authored by Jamie Davis and last updated in June 2026, contains code for deterministic execution on microcontrollers without floating-point units.

Use Cases

• Implement real-time hardware frequency monitoring based on the zero-crossing detector engine.
• Compensate for mechanical backlash and sensor noise bands based on the dead-zone backlash compensator.
• Apply low-pass smoothing to sensor telemetry based on the exponential smoothing filter core.
• Condition raw input signals for downstream closed-loop control systems based on the described pipeline.

Strengths

• Designed for deterministic execution on resource-constrained microcontrollers without floating-point units.
• Implements three specific signal processing paths (zero-crossing detection, dead-zone compensation, exponential smoothing).
• Released under the permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is a 4.9 KB text file, indicating a very limited scope focused on code rather than data records.
