GW3323 OS使用记录
当两个线程优先级相同时，两个线程的while(1)中，必须要使用 delay_5ms（），给两个相同优先级的线程相互打断的时间，不然会卡死在一个任务中，退出不了，如图为相同优先级的例程，：https://alidocs.dingtalk.com/core/api/resources/img/5eecdaf48460cde538b3ffb2a461a4b76cd2765f1144c52e91ff1ac8adf83e6bd31a09ccfd9c229465a117e9692870647a928f062610a7cdc06e418267feb22231ecf560d2c715853ae413e808b978c60dd4c2e62e4ff99c149565b860957ab4?tmpCode=7beee294-9e5f-4fec-8cdb-b3ab54808e68

当两个线程一个为高优先级，一个为低优先级时，高优先级的的delay_5ms（）的时间，为低优先级程序运行的时间，如低优先级没运行完，也会被高优先级的任务打断，故需在高优先级处留够足够多的时间，如图，高优先级留50ms的时间给低优先级：

主函数任务优先级为12，故，此时程序也可跑到主函数中，usb的枚举与数据传输都没问题，只是会慢很多https://alidocs.dingtalk.com/core/api/resources/img/5eecdaf48460cde538b3ffb2a461a4b76cd2765f1144c52e91ff1ac8adf83e6bd31a09ccfd9c229465a117e969287064593c6cd47f25038f5ee52b9fbdc063b340f677c65e8617c1f572040c7b33aac9c4d60bdbf021d4eba900dfd662445084?tmpCode=7beee294-9e5f-4fec-8cdb-b3ab54808e68
重要的一点：如果要在线程中更改蓝牙的相关东西，那么线程的优先级不能比蓝牙的优先级高
确实，线程同步和优先级管理在多任务系统中非常重要。你分享的这些经验对于避免死锁和确保任务公平执行非常有帮助。
有图吗 ？我刷不出来啊 ！！！
