…pers#10 This commit resolves multiple critical crashes and implements lazy TxRx initialization: Bug DarkFlippers#7 - Black screen/devices.c crash: - Implemented lazy TxRx initialization pattern - TxRx now remains NULL during app startup - Only allocated on first transmission to avoid device init conflicts - Removed subghz_devices_init() call from subghz_txrx_alloc() Bug DarkFlippers#8 - message_queue.c crash: - Fixed race condition with RAW callback executing after cleanup - Clear RAW callback BEFORE stopping transmission in scene exit - Added NULL check before clearing callback Bug DarkFlippers#9 - Scene flow broken (couldn't open/edit maps): - Fixed malformed #ifdef/#else/#endif preprocessor structure - Properly nested scene transitions for Official vs Custom firmware Bug DarkFlippers#10 - NULL pointer dereference when opening map: - Modified map loading to handle lazy TxRx initialization - Skip full protocol validation if TxRx is NULL - Defer validation until first transmission attempt Additional improvements: - Increased stack size from 2KB to 4KB for stability - Added comprehensive NULL safety checks throughout codebase - Added Claude Code documentation (CLAUDE.md) - All subsystems now handle graceful degradation Files modified: - helpers/txrx/subghz_txrx.c - Removed global device init, added safety checks - subghz_remote_app.c - Lazy TxRx init, fixed scene flow - subghz_remote_app_i.c - Lazy init function, safe map loading - scenes/subrem_scene_remote.c - Callback cleanup safety - views/remote.c, views/edit_menu.c - NULL safety in draw functions - application.fam - Version bump to 1.8.9, increased stack size Tested on Kiisu mntm-dev custom firmware. 🤖 Generated with Claude Code (https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
