The access volume of the previous Article exceeded 1000. Haha, so many people have never read my article. Although within the company, I highly value communication and mutual experience to avoid repeated wheel-building events, there have not been so many people looking at their own things. I still want to emphasize one thing, although I have already stressed it multiple times: friends, if you want to spare your precious time to read my article, so please make up more time to practice and use cod

Using FreeRTOS, one of the most basic program architectures is as follows:int main (void) { necessary initialization work; Create task 1; Create Task 2; ... Vtaskstartscheduler (); /* Start Scheduler * /while (1); }when the task is created, the static variable pointer PXCURRENTTCB (see section 7th, "FreeRTOS advanced 2---freertos Task creation Analysis ") points to the highest-priority readiness task. However, the task does not w

Implementation Scenario One: 1 the task in the frequency H1 (30 seconds) timing, the frequency of the task to perform the time required to exceed the frequency of the time period (30 seconds), the frequency of the task has not been completed, the next execution of the task Midway interrupted; 2 The second 30 second time node (that is, the next frequency) when scheduling tasks, because there is no idle thread (the previous frequency task takes up all the threads), there is a large number of threa

, some scheduling methods of timer are relatively simple, unable to adapt to the complexity of task scheduling in actual projects. A simple Demo instanceOther ways to focus on the timer Cancel (): Terminates timer timer, discards all currently scheduled tasks (Timetask also exists cancel () method, but terminates Timetask) Purge (): Removes the canceled task from the timer's task queue and returns the number JDK thread pool support for scheduled task scheduling: Schedulede

The quartz scheduler executes the scheduling task jobdetail in multi-thread mode. The default thread pool size is 10. That is to say, if 10 jobs in the scheduler are working (the thread is not finished ), even if jobdetail is triggered, the new jobdetail will not be executed. That is to say, the blocking condition is that the number of jobdetail running in the scheduler
