# Schematic Workflow Fix - Issue #26
|
|
|
|
## Problem Summary
|
|
|
|
The schematic workflow was completely broken due to incorrect usage of the kicad-skip library:
|
|
|
|
1. **`create_project`** only created PCB files, no schematic
|
|
2. **`create_schematic`** created orphaned schematic files not linked to projects
|
|
3. **`add_schematic_component`** called non-existent `schematic.add_symbol()` method
|
|
4. Project files didn't reference schematics in their structure
|
|
|
|
## Root Cause
|
|
|
|
The kicad-skip library **does not support creating symbols from scratch**. The only way to add symbols is by **cloning existing symbol instances**.
|
|
|
|
From kicad-skip documentation:
|
|
> "symbols: these don't have a new()" because they require complex mappings to library elements, pins, and properties.
|
|
|
|
## Solution
|
|
|
|
### 1. Template-Based Approach
|
|
|
|
Created a template schematic (`python/templates/template_with_symbols.kicad_sch`) with:
|
|
- Complete `lib_symbols` section defining R, C, LED symbols
|
|
- Three template symbol instances placed off-screen at (-100, -110, -120)
|
|
- Template symbols marked as `dnp yes`, `in_bom no`, `on_board no` so they don't interfere
|
|
|
|
### 2. Updated Files
|
|
|
|
**python/commands/project.py:**
|
|
- Now creates both `.kicad_pcb` AND `.kicad_sch` files
|
|
- Project file includes schematic reference in `sheets` array
|
|
- Copies template schematic with cloneable symbols
|
|
|
|
**python/commands/schematic.py:**
|
|
- Uses template file instead of creating from scratch
|
|
- Proper minimal schematic structure when template unavailable
|
|
|
|
**python/commands/component_schematic.py:**
|
|
- Completely rewritten to use `clone()` API
|
|
- Maps component types to template symbols
|
|
- Proper UUID generation for each cloned symbol
|
|
- Correct position setting: `symbol.at.value = [x, y, rotation]`
|
|
|
|
### 3. Correct Workflow
|
|
|
|
```python
|
|
from commands.project import ProjectCommands
|
|
from commands.schematic import SchematicManager
|
|
from commands.component_schematic import ComponentManager
|
|
|
|
# Step 1: Create project (creates both PCB and schematic)
|
|
project_cmd = ProjectCommands()
|
|
result = project_cmd.create_project({
|
|
"name": "MyProject",
|
|
"path": "/path/to/project"
|
|
})
|
|
|
|
# Step 2: Load the schematic
|
|
sch = SchematicManager.load_schematic(result['project']['schematicPath'])
|
|
|
|
# Step 3: Add components by cloning templates
|
|
component_def = {
|
|
"type": "R", # Maps to _TEMPLATE_R
|
|
"reference": "R1", # Component reference
|
|
"value": "10k", # Component value
|
|
"footprint": "Resistor_SMD:R_0603_1608Metric",
|
|
"x": 50.8, # Position in mm
|
|
"y": 50.8, # Position in mm
|
|
"rotation": 0 # Rotation in degrees
|
|
}
|
|
symbol = ComponentManager.add_component(sch, component_def)
|
|
|
|
# Step 4: Save the schematic
|
|
SchematicManager.save_schematic(sch, result['project']['schematicPath'])
|
|
```
|
|
|
|
## Supported Component Types
|
|
|
|
Currently supported template symbols:
|
|
- `R` - Resistor (maps to `_TEMPLATE_R`)
|
|
- `C` - Capacitor (maps to `_TEMPLATE_C`)
|
|
- `D` or `LED` - LED (maps to `_TEMPLATE_D`)
|
|
|
|
To add more component types, update:
|
|
1. `python/templates/template_with_symbols.kicad_sch` - Add lib_symbol definition and template instance
|
|
2. `python/commands/component_schematic.py` - Add mapping in `TEMPLATE_MAP`
|
|
|
|
## Testing
|
|
|
|
Comprehensive test created at `/tmp/test_schematic_workflow.py`:
|
|
- Creates project with schematic
|
|
- Loads schematic
|
|
- Adds R, C, LED components
|
|
- Saves schematic
|
|
- Validates with `kicad-cli sch export pdf`
|
|
|
|
All tests passing ✓
|
|
|
|
## Files Modified
|
|
|
|
- `python/commands/project.py` - Added schematic creation
|
|
- `python/commands/schematic.py` - Fixed template usage
|
|
- `python/commands/component_schematic.py` - Rewritten to use clone() API
|
|
- `python/templates/empty.kicad_sch` - Minimal template (created)
|
|
- `python/templates/template_with_symbols.kicad_sch` - Template with cloneable symbols (created)
|
|
|
|
## Limitations
|
|
|
|
1. Can only add components that have templates defined
|
|
2. Template symbols remain in schematic (but marked as DNP/not in BOM)
|
|
3. Complex symbols (multi-unit, hierarchical) may need custom templates
|
|
|
|
## Future Improvements
|
|
|
|
1. Add more component templates (transistors, connectors, ICs)
|
|
2. Dynamic template generation from KiCad symbol libraries
|
|
3. Auto-hide template symbols in schematic
|
|
4. Support for custom user templates
