首页A function that implements a task must not exit or attempt to return to its caller as there is nothing to return to. If a task wants to exit it should instead call vTaskDelete( NULL ). Artificially force an assert() to be triggered if configASSERT() is defined, then stop here so application writers can catch the error

fcron-3.2.1.src.tar.gz_Home To You_ION_linux 秒级计划任务软件

Fcron is a scheduler. It aims at replacing Vixie Cron, so it implements most of its functionalities. But contrary to Vixie Cron, fcron does not need your system to be up 7 days a week, 24 hours a day : it also works well with systems which are running only occasionnally (contrary to anacrontab). In other words, fcron does both the job of Vixie Cron and anacron, but does even more and better :)) ... To do so, fcron allows you to use the standard mode in which you tell it to execute one command at a given date and hour (for instance every day at 6am), or to run a command depending to the system up time. For example : Run the task 'save /home/ directory' every 3h15 of system up time. Of course, in order to make it really useful, the time remaining until next execution is saved each time the system is stopped.

这段文本是针对在FreeRTOS中实现任务时的一些规则和最佳实践。它提到，任务函数不应该尝试退出或返回给调用者，因为任务函数没有返回值。如果一个任务想要退出，应该调用vTaskDelete(NULL)函数来删除任务。此外，如果在FreeRTOS中定义了configASSERT()宏，它可以用来强制触发一个断言错误。这样做是为了帮助应用程序开发人员捕捉错误和调试问题。总结起来，这段文本强调了在FreeRTOS中任务函数的正确退出方式以及如何使用configASSERT()宏来辅助调试。
