求助关于UCOSII的问题

xp3539989

我在正点原子探索版上移植了UCOSII 系统，然后创建了三个任务，为什么这三个任务不执行呢？

bj2008wyou

好歹贴下你创建的三个任务前后之间的代码吧，你这样是让人家凭空猜测啊，猜测也要有根据的

---------------------------------
不好意思，因为程序太大，把部分任务函数贴出来，因为现在创建的第一个任务函数感觉都没有执行，望有过类似经验的大侠，帮帮忙，不胜感激

????? 已经爬了很久了,对UCOS还不甚了解，现在项目急，只能求大侠帮帮

bj2008wyou

看不出来什么，我只能说，你要去找原因了。现在你说第一个任务感觉没有执行。那你可以这样做啊，注释掉第一个任务里面所有的代码，在里面开启系统定时器和添加一个点亮LED的程序的小程序，如果能看到LED亮就说明有执行，只是你代码执行结果不是预期的；没有亮就是根本就没切换任务，那就是你移植部分代码的问题了

什么项目一定要用uCOS?
STM32平台一般用不到系统。

有可能是你选择的优先级有问题,最高级别的优先级,还有最低2位的优先级被系统占用了
你优先级可以选择4,5,6,7(注意:还要看你最大的优先级,不要溢出了)

兄弟  你说的对，昨天我也是改变了优先级才弄好的，我改成10,7,3，4，优先级范围OS_LOWEST_PRIO           10u ，我之前是做增强型51单片机开发的，从来没用过UCOS，还得摸索一段时间，谢谢了啊！
