❶ UCOS-III真的无限个任务吗
理论上是.因为它支持相同优先级的任务.所以只要有ram.就可以创建任务.
❷ ucos-ii 有多少行代码
文件清单如下： OS_SEM.C OS_MUTEX.C OS_FLAG.C OS_MBOX.C OS_Q.C OS_MEM.C OS_TASK.C OS_TIME.C OS_TMR.C OS_CORE.C OS_CPU_A.ASM OS_CPU_C.C总的代码量应该有几版万行吧！权
❸ ucosiii移植需要修改哪些文件
上层函数不需要修改有一些CPU相关的汇编文件需要手动修改UCOS官方提供的DEMO就是基于STM32的，应该可以直接用
❹ 不同单片机用到的需要移植的UCOSIII源码是不一样的吗
C语言有个很大的好处就是可移植性好。各种不同的单片机应用平台，只是一些寄存器，外设等不同，但主体程序不会相差太大，只需要修改一些头文件或者一些寄存器等等。
❺ UCOS II怎么没有OS_CPU.H OS_CPU_C.C OS_CPU_A.ASM。这个几个文件，还有INCLUDES.H
这个有啊！估计你们有好好找啊！这个在Micrium\software\uC-CPU\ARM-Cortex-M3\IAR(最后的两个是因为我移植在Cortex-M3上，编译器用的是IAR)。如果你用的是别的内核，编译器用的其它的也是有相对应的。希望能对你有帮助！
❻ ucos移植到51单片机上需要改那几个文件
Os_cpu.hOs_cpu_a.sOs_cpu_c.c这三个函数的修改是必不可少的，在介绍ucos移植的文章里都会提到，网上应该有不少ucos移植到51单品机上的范例
❼ ucosiii源码中有多个os-app-cfg
