The specific application task priority allocation implementation flow is as follows:
step one, executing an original plant SDK demo program, acquiring priorities of all executed tasks of the original plant SDK demo by utilizing API (application program interface) interfaces uxTaskGetNumberOfTasks and uxTaskGetSystemState in the FreeRTOS, and screening out the priority value of the task with the lowest priority (note: except the task with the priority of 0, the task with the priority of 0 is a system idle task, and the lower the priority of the FreeRTOS system is, the smaller the numerical value is).
And step two, taking the screened priority values as the highest priority values of the application tasks, namely, the priority levels of the first level, and sequentially decreasing the priority values of other levels.
And step three, filling corresponding priority levels in the tasks during creation according to the application task priority allocation method described above.
And step four, executing a user program, and printing and outputting the priorities of all tasks for the user to check.
And step five, in the program execution process, printing running time statistics of each task at intervals for a user to refer to whether the task needs to be adjusted (whether the task needs to be split and recombined) and the priority needs to be reclassified, and if so, re-executing from the step two after adjustment.
In the embodiment, the application task priority distribution in the embedded operating system (FreeRTOS) is simplified, the task priority distribution has reference when a developer creates a new task, and the reasonable priority can be selected without paying attention to the priority of other tasks, so that the multitask program can stably and efficiently run in the FreeRTOS real-time operating system.
