v1.1.0

What's New in v1.1.0

FreeRTOS Optional Library

• One-click FreeRTOS integration for all 4 MCU families (STM32F1/F4, GD32F1/F4)
• Auto-copies kernel sources + Cortex-M3/M4 RVDS port + heap_4 memory management
• DWT cycle counter for microsecond delays (no SysTick conflict)
• Shared SysTick_Handler: auto-forwards to FreeRTOS after scheduler starts

HXTAL Crystal Configuration

• External crystal frequency selector (8 MHz / 25 MHz) in project settings
• Auto-corrects system clock: PLL macros for GD32F4xx, PLL_M for STM32F4xx, compiler HSE/HXTAL defines
• No more manual code editing for different crystal frequencies

Other Features

• Help button with usage guide (English/Chinese)
• GD32F4xx: 5 new F470 series chips added (total 14)
• Default UI language now English
• Delay module refactored: bare-metal / UCOS / FreeRTOS three-tier

Bug Fixes

• FreeRTOSConfig.h missing stdio.h causing printf warnings
• SYSTEM_SUPPORT_OS macro not effective due to missing sysconfig.h include
• STM32F4xx PLL_M auto-corrected for crystal frequency
• STM32 FreeRTOS UART templates added fputc retargeting
• GD32F470 RAM specs corrected per official datasheet
• System clock patching now covers all file copies
