New 2-phase sync (Stabilization + Silence detection).
Refactored GPIO macros for faster execution.
Cleaned up SCPH model definitions and fixed backslash warnings.
Removed unused global variables to save RAM.
- Core logic: Optimized 'isDataSector' using a single 0xD0 bitwise mask for faster 0x41 sector detection.
- Architecture: Moved 'board_detection()' into 'Init()' for a cleaner entry point in 'main()'.
- Settings: Updated 'settings.h' with improved constant definitions and macro organization.
- Performance: Reduced instruction count in the main loop and improved peripheral power management.
- Updated all input read macros (PIN_SQCK_READ, PIN_SUBQ_READ, etc.) to use double logical NOT (!!) operators.
- This ensures bitwise masks are normalized to a pure 0 or 1 boolean value.
- Optimization: Allows the compiler to use faster AVR branch instructions (SBIC/SBIS) and improves compatibility with direct equality tests.
- Updated inline documentation for better clarity on bitwise operations.
- board_detection: Added early exit for newer boards and tightened the sampling loop to reduce CPU overhead.
- captureSubQ: Simplified clock-edge synchronization and localized buffers to improve register allocation.
- performInjectionSequence: Replaced bit-calculation math with a streamlined byte-shift approach. Refined WFCK modulation to ensure zero-jitter phase locking.
- logic_Standard/5903: Refactored pattern matching into a decision tree. Factorized redundant buffer checks (scbuf[1]/[6]) and replaced multiple equality tests with range comparisons.
Optimization results:
- Reduced Flash memory footprint (smaller binary size).
- Improved execution speed by removing redundant logical operations.
- Increased signal stability during the critical injection phase.
Removal of ISR and reduction of code in the BIOS patch, for improved portability and robustness.
For now it is only available for the SCPH-100 and 102.
performInjectionSequence(): Deep refactor with a cleaner.
captureSubQ(): Faster bit-banging and improved timing accuracy.
board_detection(): Optimized logic .
General Cleanup: Fixed all warnings and minimized memory footprint.
Modular breakdown: Separated main logic into
- captureSubQ,
- logic_SCPH_5903,
- logic_Standard,
- performInjectionSequence.
