原则上越少越省内存,以内核对象 100 个为例,一个对象名占用 8 字节,总共是 800 字节。但是考虑到struct rt_object结构体定义,后面跟了两个 rt_uint8_t 型变量。 RT_NAME_MAX 可以定义成 2n + 2 Q2. RT_DEBUG 如非必要,不要开启内核调试。除非,你真的想学习内核,或者调试内核的问题。
在 RT-Thread 系统中,任务通过线程实现的,RT-Thread 中的线程调度器也就是 以上提到的任务调度器。 此次学习之旅根据RT-Thread官方文档《RT-THREAD 编程指南》目录进行,同时参考其中内容。在源码解读方面采用直接在源代码中做注释的方式,这样既有开发者的官方注释,又有自己的思考,想法,更加清晰明了。
