Dec 1, 2025December 2025 (OpenSiFli/SiFli-SDK) delivered targeted memory optimization and robust input configuration safety checks, enhancing stability on memory-constrained devices and reducing configuration errors. Key outcomes include a memory realignment for LPSYS RAM (896k) and a compile-time validation to prevent TOUCH IRQ misconfiguration when BSP_TOUCH_IRQ_FROM_DATASVC is defined. These changes reduce memory waste, lower risk of IRQ misassignment, and improve product reliability across edge devices.

Jul 1, 2025In July 2025, OpenSiFli/SiFli-SDK delivered two new feature examples and a stability fix that strengthen developer tooling, showcase LVGL9 integration, and improve build compatibility. The CPU Usage Profiler Demo provides a comprehensive, well-documented example including configuration, usage guidance, CPU usage statistics, thread switching history, interrupt history, and detailed metrics, with hardware requirements and setup instructions plus FINSH commands for interactive profiling. Animated GIF Playback with LVGL9 demonstrates the project’s graphics capabilities by introducing an agif-based example integrated with lvgl9. A fix to agif.h for LVGL_V9 improves build stability by conditionally including lv_image_private.h, reducing compiler errors on the lvgl_v9 path. These efforts enhance onboarding, debugging efficiency, and cross-version compatibility, enabling faster demonstrations and more reliable deployments.

Jun 1, 2025June 2025: Delivered enhanced multi-bin support and modular resource management for the sf32lb52-lcd_n16r8 watch example in OpenSiFli/SiFli-SDK. By updating linker scripts to enable independent ROM2 and ROM3 sections for .ROM3_IMG and TTF font data, the update increases modularity, reduces asset coupling, and lays groundwork for scalable resource updates. This work improves build flexibility, enables faster iteration cycles, and strengthens the foundation for future resource-driven features across the SDK.
