FreeRTOS内存管理一章中描述了FreeRTOS如何使用RAM，并且描述了RAM是如何分配给RTOS内核的。 如果你要将演示例程移植到一个RAM稍小的微处理器上，那么你可能需要减少configTOTAL_HEAP_SIZE的值（位于FreeRTOSConfig.h），并且减少演示例程的任务个数。可以通过简单的注释掉不需要的任务来实现。 如 … Visa mer 对于一个特定平台，大多数（不是全部）硬件接口代码包含在一个叫做FreeRTOS/source/portable/[编译器]/[微控制器/port.c的文件中， … Visa mer C启动文件和链接脚本都属于处理器和编译器特定的。不推荐尝试从无到有的创建这些文件，应该到FreeRTOS演示工程中寻找一个合适的来修改。 要特别小心ARM7启动文件。它必须将IRQ中断服务程序入口地址配置到快速中断处理向量 … Visa mer 编译器可以为嵌入式系统提供某些特定的C语言扩展。比如某个特定关键字可以标识出一个函数是中断处理服务函数。 扩展的C语言部分，是不属于 … Visa mer 每一个工程通常都会定义一些宏，这些预处理宏定义了一些要被编译的特定的硬件接口代码。要包含portmacro.h文件才能识别这些宏。比如，当使用GCC编译MegaAVR硬件接口代码时，宏GCC_MEGA_AVR必须被定义；当使用IAR编 … Visa mer
