Module analog_processor 

AnalogProcessor for EV_ABS event handling with deadzone filtering

This module provides analog stick processing with:

• Deadzone filtering (values within deadzone return None)
• Sensitivity adjustment (multiplier for output values)
• Response curve application (Linear, Exponential)
• Per-device calibration state tracking

Processing Pipeline

1. Deadzone Filter: If |value| < deadzone, return None (no event)
2. Normalization: Map (deadzone, max) to (0, max)
3. Sensitivity: Apply multiplier (default 1.0)
4. Response Curve: Apply Linear or Exponential transformation

Device Configurations

Each device has independent analog configuration:

• deadzone: 0-32767 range (default ~14000 for ~43%)
• sensitivity: 0.1-5.0 multiplier (default 1.0)
• response_curve: Linear or Exponential

Examples

let processor = AnalogProcessor::new();

// Process analog event
if let Some(processed) = processor.process_event("1532:0220", 61000, 25000).await {
    // Send processed value to macro engine
} else {
    // Value was filtered by deadzone
}

// Configure device
processor.set_deadzone("1532:0220", 16000).await;
processor.set_sensitivity("1532:0220", 1.5).await;
