Handler Implementation Notes
Current MicrochipHandler Issues
- HashSet Usage: Uses
new HashSet<>()
instead of Set.of()
for immutable sets
- Pattern Duplication: Many patterns registered for both base type and manufacturer-specific type
- No Debug Statements: Clean implementation without println
Pattern Registration
The handler registers patterns for:
- All dsPIC variants (30F, 33FJ, 33EP, 33EV, 33CH, 33CK)
- 8-bit PIC (10F, 10LF, 12F, 12LF, 16F, 16LF, 18F, 18LF)
- 16-bit PIC24 (24F, 24FJ, 24EP, 24HJ)
- 32-bit PIC32 (MX, MZ, MM, MK, WK)
- Memory (24AA, 24LC, 24FC, 25AA, 25LC, 93LC, 93AC)
- Interface ICs (MCP25xx, MCP22xx, MCP79xx)
Package Extraction Logic
Current implementation handles:
- Hyphen-separated suffixes:
-P
, -PT
, -ML
, -SO
, -SS
, -ST
- Combined temp+package:
-I/P
, -E/SO
, etc.
- Embedded codes:
/P
, /PT
, /ML
, /SO
Series Extraction
- PIC: Extracts up to first non-alphanumeric character
- dsPIC33: Special handling to include sub-family (FJ, EP, etc.)
- Memory: Extracts first 4 characters (e.g., "24LC")
- MCP: Extracts "MCP" + numeric suffix
Supported ComponentTypes
