The device features an advanced 3-Round Calibration System that provides superior touch accuracy through multiple refinement passes.

Because of Problems with a standard 5 Point calibration, caused by an unknown transformation I implemented my own approach:

• ❌ No complex multi-point sampling
• ❌ No pixel-perfect alignment required

Instead:

• ✅ Fully automatic - System knows if you're left/right/up/down
• ✅ Zone-based detection - Touch target, system auto-corrects
• ✅ Real-time convergence - Parameters adjust while you touch
• ✅ 3-round refinement - Progressive accuracy improvement
• ✅ 13 total steps - Complete calibration with multiple passes
• ✅ Fallback system - Confirmation dialog with auto-revert

📖 Read full documentation

Round 1: Full Calibration (5 steps)

1. Offset X - Touch red dot in center, system auto-adjusts horizontal offset
2. Offset Y - Touch red dot in center, system auto-adjusts vertical offset
3. Rotation - Touch red dot on vertical line, system auto-adjusts rotation
4. Scale X - Touch red dot on right edge, system auto-adjusts horizontal scale
5. Scale Y - Touch red dot on bottom edge, system auto-adjusts vertical scale

Round 2: Refinement (5 steps)

• Refine Offset X - Ultra-fine horizontal adjustment
• Refine Offset Y - Ultra-fine vertical adjustment
• Refine Rotation - Ultra-fine angle adjustment
• Refine Scale X - Ultra-fine horizontal scale
• Refine Scale Y - Ultra-fine vertical scale

Round 3: Final Offset (2 steps)

• Final Offset X - Ultimate horizontal precision
• Final Offset Y - Ultimate vertical precision

Summary Step

• Calibration complete! - Touch to exit and return to settings

1. Access Calibration:

   • Go to Settings → Touch Calibration
   • Read on-screen instructions

2. Follow the 3-Round Process:

   • Round 1: Complete calibration (5 steps, each with Coarse → Fine)
   • Round 2: Refinement of all parameters (5 ultra-fine steps)
   • Round 3: Final offset adjustment (2 maximum precision steps)
   • Just touch and hold the red dot or line as shown
   • System adjusts parameters automatically
   • Release when text says "OK! Release finger"

3. Confirmation:

   • Calibration is immediately applied for testing
   • On next boot, a confirmation dialog appears
   • Choose Keep or Revert (10-second auto-revert if no action)
   • Once confirmed, calibration is permanent

The 3-Round Calibration System uses progressive refinement to achieve optimal accuracy:

Round 1: Full Calibration (Coarse → Fine)
┌─────────────────────────────────────────┐
│ Step 1: Offset X    (Coarse → Fine)    │
│ Step 2: Offset Y    (Coarse → Fine)    │
│ Step 3: Rotation    (Coarse → Fine)    │
│ Step 4: Scale X     (Coarse → Fine)    │
│ Step 5: Scale Y     (Coarse → Fine)    │
└─────────────────────────────────────────┘

Round 2: Refinement (Ultra-Fine)
┌─────────────────────────────────────────┐
│ Step 6:  Refine Offset X  (Ultra-Fine) │
│ Step 7:  Refine Offset Y  (Ultra-Fine) │
│ Step 8:  Refine Rotation  (Ultra-Fine) │
│ Step 9:  Refine Scale X   (Ultra-Fine) │
│ Step 10: Refine Scale Y   (Ultra-Fine) │
└─────────────────────────────────────────┘

Round 3: Final Offset (Maximum Precision)
┌─────────────────────────────────────────┐
│ Step 11: Final Offset X (Max Precision)│
│ Step 12: Final Offset Y (Max Precision)│
└─────────────────────────────────────────┘

The 3-round calibration process:

1. Round 1: Establishes baseline calibration with coarse + fine passes
2. Round 2: Refines all parameters with ultra-fine adjustments
3. Round 3: Achieves maximum precision with final offset adjustments
4. Progressive accuracy: Each round builds upon the previous for optimal results
5. Origin Correction: A hardcoded origin correction is added to compensate standard origin offset

This creates a multi-pass refinement system that guarantees superior calibration accuracy!

Best method: Use the Preset Editor keyboard

1. Go to Settings → Edit Presets
2. Select any preset
3. Try typing on the on-screen keyboard
4. Test all screen regions (center, edges, corners)
5. If touch feels off → Just re-run calibration (takes 45-65 seconds for full 3-round process!)

Why the keyboard?

• Small keys in all screen regions
• Immediate visual feedback
• Most challenging UI element - if keyboard works, everything works!

Calibration Timing:

• Round 1: 20-30 seconds (5 steps × 4-6 seconds each)
• Round 2: 15-25 seconds (5 refinement steps × 3-5 seconds each)
• Round 3: 6-10 seconds (2 final offset steps × 3-5 seconds each)
• Total: 45-65 seconds for complete 3-round calibration

If your device becomes unusable due to bad calibration, you can reset to factory defaults:

1. Go to Settings → Touch Calibration
2. The calibration will use factory defaults during the process
3. Complete the 3-round calibration process (13 steps total)

If touch is completely broken:

1. Open src/main.cpp around line 125
2. Uncomment the emergency reset line:

   // === NOTFALL: Touch Calibration Reset ===
   resetTouchCalibrationToDefaults();  // ← Remove the //

3. Flash to device
4. Re-comment the line and flash again

To change factory default values, edit src/hardware/display/lvgl_driver.cpp line 27-34:

static const float DEFAULT_CAL_MATRIX[7] = {
    0.0f,    // [0] offset_x
    0.85f,   // [1] scale_x - Try 0.80-1.05
    0.0f,    // [2] shear_xy - Usually 0.0
    0.0f,    // [3] offset_y
    0.0f,    // [4] shear_yx - Usually 0.0
    1.0f,    // [5] scale_y - Try 0.80-1.05
    1.0f     // [6] divisor - Leave at 1.0
};

Tested Defaults: are saved in the Config.h

Recommendation: Use the automatic 3-round calibration instead of manual adjustment. It provides optimal, device-specific calibration in 45-65 seconds with superior accuracy through progressive refinement!

You can edit presets on-device via Settings → Edit Presets, but the keyboard can be challenging to use. For easier customization, edit presets before compilation.

Adding Presets Before Compilation (Recommended):

See Adding Custom Presets section for editing tcg_presets.cpp before building.

Extend Battery Life:

1. Enable Auto-Dim (Settings → Power Settings → Auto-Dim → ON)
2. Enable Sleep (Settings → Power Settings → Sleep → ON)
3. Reduce brightness (Settings → Power Settings → Brightness → 30-50%)

Battery Protection:

• Low Battery Dimming activates automatically at ≤15%
• Wake device by pressing power button
• Critical Battery Protection triggers at ≤2%
• Device enters deep sleep to prevent battery damage

Charging:

• Connect USB-C cable
• Device can operate while charging
• Low Battery Dimming disabled during charging
• Battery percentage may show 0% while charging (normal behavior)

The Life Puck includes comprehensive power management to extend battery life and protect the battery from damage.

• Function: Reduces display to 25% brightness after inactivity
• Default: 60 seconds
• Configuration: Power Settings → Auto-Dim
• Benefits: Extends battery life during pauses in gameplay

• Function: Turns off display completely after extended inactivity
• Default: 300 seconds (5 minutes)
• Configuration: Power Settings → Sleep
• Wake: Touch screen anywhere

• Function: Forces display to 5% brightness at ≤15% battery
• Automatic: Activates when battery drops to critical levels
• Restoration: Automatically restores brightness when battery > 15%
• USB Detection: Disabled when charging (voltage < 1V)
• Configuration: Power Settings → Low Battery Dimming

Purpose: Prevents permanent battery damage from deep discharge

How It Works:

1. Battery drops to ≤2%
2. 2-second verification timer starts
3. After 2 seconds, voltage is re-checked
4. If voltage is between 1V and 3.3V → Deep sleep activated
5. If voltage < 1V (USB charging) or > 3.3V → Protection canceled

Smart USB Detection:

• Voltage < 1V → USB charging detected, no shutdown
• 30-second timeout handles power switch toggling during USB charging
• 10-second boot grace period allows voltage readings to stabilize

Why This Matters:

• The original Life Puck had no automatic battery protection
• Without this feature, battery can drain to 2.7V, causing permanent damage
• This system ensures battery longevity and prevents costly replacements

Wake from Deep Sleep:

• connect USB-C cable
• Press and hold power button for 2 seconds (non C Model)

For Maximum Battery Life:

1. Enable Auto-Dim and Sleep
2. Set brightness to 30-50%
3. Enable Low Battery Dimming
4. Charge battery before it reaches 15%

For Maximum Performance:

1. Set brightness to 70-100%
2. Disable Auto-Dim
3. Set Sleep timeout to 0 (disabled)
4. Keep Low Battery Dimming enabled (battery protection)
