|
||||
#### Object-Oriented Design Excellence:
|
||||
```rust
|
||||
// BEFORE: Inconsistent patterns
|
||||
let virtual_axis = VirtualAxis::new(5); // Has methods
|
||||
let gimbal_axis = GimbalAxis::default(); // Just data structure
|
||||
axis_manager.process_axis_values(); // Manager does everything
|
||||
|
||||
// AFTER: Consistent object-oriented patterns
|
||||
let virtual_axis = VirtualAxis::new(5);
|
||||
let gimbal_axis = GimbalAxis::new(); // Same constructor pattern
|
||||
for axis in &mut axes {
|
||||
axis.process_value(filtered, &expo); // Each axis manages itself
|
||||
}
|
||||
```
|
||||
|
||||
#### Comprehensive Method Suite:
|
||||
- **Construction methods** - `new()`, `new_with_calibration()`, `calibrate()` for flexible setup
|
||||
- **Processing methods** - `process_value()`, `process_throttle_hold()`, `process_hold()` for self-contained logic
|
||||

|
||||
- **Activity detection** - `check_activity()` for independent state change tracking
|
||||
|
||||
#### Architectural Benefits:
|
||||
- **Design consistency** - both axis types follow identical patterns (constructor, methods, encapsulation)
|
||||
- **Individual testability** - each axis method can be unit tested independently
|
||||

## 🚀 LATEST: Clean Separation Architecture - Calibration Module Refinement - COMPLETED! ✅
|
||||
|
||||
### ✅ Unified SpecialAction-Based Button Handling - COMPLETED:
|
||||
|
||||
#### Major Architecture Improvement - Clean Separation of Concerns:
|
||||
After implementing a unified SpecialAction approach, we identified architectural issues with forcing SpecialAction into calibration.rs. The solution was refined to maintain **perfect separation of concerns**:
|
||||
|
||||
**Architecture Problems Identified:**
|
||||
- Mixed concerns: SpecialAction belonged in input handling, not calibration logic
|
||||
- Over-consolidation: Single massive method vs focused, single-responsibility methods
|
||||
- Artificial coupling: Calibration module forced to understand input concepts
|
||||
|
||||
**Final Clean Architecture Implemented:**
|
||||
- **SpecialAction stays in main.rs** - where input handling belongs
|
||||
- **calibration.rs stays pure** - focused only on calibration operations
|
||||
- **Separate focused methods** - each method has single responsibility
|
||||
|
||||
#### 12. buttons.rs Extended SpecialAction - COMPLETED ✅
|
||||
- **Extended SpecialAction enum** with calibration-specific actions:
|
||||
```rust
|
||||
pub enum SpecialAction {
|
||||
None,
|
||||
Bootloader,
|
||||
StartCalibration,
|
||||
CancelCalibration,
|
||||
ThrottleHold(u16),
|
||||
VirtualThrottleToggle,
|
||||
CalibrationSetModeM10, // NEW
|
||||
CalibrationSetModeM7, // NEW
|
||||
CalibrationSave, // NEW
|
||||
}
|
||||
```
|
||||
- **Enhanced button detection** - `check_special_combinations` detects calibration mode buttons during calibration
|
||||
- **Clean input abstraction** - buttons translate to semantic actions
|
||||
|
||||
#### 13. calibration.rs Clean Focused Methods - COMPLETED ✅
|
||||
- **Removed SpecialAction dependency** - calibration module stays pure
|
||||
- **Separate focused methods** with clean interfaces:
|
||||
- `update_dynamic_calibration()` - continuous min/max tracking during calibration
|
||||
- `set_gimbal_mode_m10()` - focused M10 mode setting with axis reset
|
||||
- `set_gimbal_mode_m7()` - focused M7 mode setting with axis reset
|
||||
- `save_calibration()` - clean calibration save and mode exit
|
||||
- **Single responsibility principle** - each method does one thing well
|
||||
- **No artificial consolidation** - separate methods are cleaner and more maintainable
|
||||
|
||||
#### 14. main.rs Clean Input Handling - COMPLETED ✅
|
||||
- **SpecialAction handling** stays in main.rs where it belongs:
|
||||
```rust
|
||||
match action {
|
||||
SpecialAction::CalibrationSetModeM10 => {
|
||||
if calibration_manager.set_gimbal_mode_m10(&mut axes, &smoothers) {
|
||||
axis_manager.set_gimbal_mode(calibration_manager.get_gimbal_mode());
|
||||
}
|
||||
}
|
||||
SpecialAction::CalibrationSave => {
|
||||
calibration_manager.save_calibration(&axes, &mut write_fn);
|
||||
}
|
||||
// ... other actions
|
||||
}
|
||||
// Always do dynamic tracking when active
|
||||
calibration_manager.update_dynamic_calibration(&mut axes, &smoothers);
|
||||
```
|
||||
- **Perfect separation** - input handling separate from calibration logic
|
||||
- **Clean coordination** - main.rs coordinates between modules without mixing concerns
|
||||
|
||||
### 🧪 Enhanced Testing Infrastructure - 74 TESTS PASSING ✅
|
||||
|
||||
