Build Note: mpk_build_1526.mpk

📦 Build Identifier

• Filename: mpk_build_1526_legcay_pwm_fix.mpk
• Build Number: 1526
• Build Type: Library Patch / PWM Bugfix
• Date: 5 November 2025
• Author: Angel Mier (SourceForge contributor)

🧩 Components Included

• Updated PWM library for legacy PIC chips
• Fix for HPWM compilation error on PIC16F876A and similar devices

🛠️ Changes & Fixes

• Resolved bug where HPWM failed to compile when assigning fractional values to DC1B0
• Error previously triggered by code like:
  Error: Cannot store 2.6 in the byte variable DC1B0 (System Include)
• Fix confirmed to work with standard 40kHz PWM brightness ramp code

✅ Validation & Testing

• Test Status: ✅ Confirmed working by user samco
• Tested By: Angel Mier, samco (SourceForge users)
• Test Notes:
• Issue reproducible in Build 1523
• Workaround (lowering clock speed) no longer needed
• Patch validated with hpwm test1.gcb sample

📁 Deployment Notes

• Target Environment: GCSTUDIO IDE, PIC16F876A and similar legacy chips
• Dependencies: GCBASIC Build 1526 or later
• Installation Instructions:
• Download PWM_build_1526.mpk from SourceForge
  Discussion Thread or this post.
• Double-click .mpk file to install via GCSTUDIO
• Recompile affected projects

📝 Additional Notes

Build Note: mpk_build_1527.mpk

📦 Build Identifier

• Filename: mpk_build_1527_PIC-AS_reverse_fix.mpk
• Build Number: 1527
• Build Type: Library Patch / Config Parser Bugfix
• Date: 12 November 2025
• Author: EvanV

🧩 Components Included

• Updated configuration file parser for FreeBASIC integration
• Fix for incomplete loading in ReverseCfgFileLookup array on legacy PIC config files

🛠️ Changes & Fixes

• Resolved bug where ReverseCfgFileLookup failed to load all relationships during config file parsing
• Issue previously caused only a single CVALUE entry per CSETTING to load (when <value> matched <mask> by coincidence), skipping others
• Fix ensures all CVALUE entries are populated sequentially, with fields: .Value (setting name), .Org (raw value), .State (primary name), .Config (combined string)
• Confirmed to work with standard PIC config samples (e.g., full FOSC oscillator options loaded)

✅ Validation & Testing

• Test Status: ✅ Confirmed working by user evanv
• Tested By: EvanV
• Test Notes:
• Issue reproducible in Build 1526
• No workarounds needed; processes all lines without premature resets
• Patch validated with config_test.gcb sample (loads 4+ entries for multi-value settings)

📁 Deployment Notes

• Target Environment: GCSTUDIO IDE, FreeBASIC-based PIC config parsers
• Dependencies: GCBASIC Build 1527 or later
• Installation Instructions:
• Download mpk_build_1527_PIC-AS_reverse_fix.mpk from this post.
• Double-click .mpk file to install via GCSTUDIO
• Recompile affected projects

📝 Additional Notes

• This patch resolves a long-standing config loading bug for PIC relationship lookups
• Recommended for all users parsing legacy config files in FreeBASIC/GCBASIC
