The porting of the operating system means that the kernel of the real-time system can run on the microprocessor. The uc/os-ii should be ported to the CPU used before it can be applied. In the uc/os-ii transplant, the processor must meet some requirements: L processor C compiler can generate reentrant code L Processor support interrupt, and can produce a timing interrupt L in C can be on/off interrupt L proc

from happening, it makes you ready to perform a task switch when the task switchParameters: NoneBecause task scheduling is usually done by ostimedly (). In this function, the current task execution is suspended. Also see if the Task Scheduler table has a priority-ready task. If the current task runs, call Osschedlock () to lock the scheduler so that the current task is suspended when you call ostimedly (). However, because the scheduler is locked, it does not allow other tasks to use the CPU. I
This is the class diagram of the UC weapon system, and I will not say every weapon, only the analysis of knives and chargun implementations, because the others are similar. Ucweapon is the root of the weapon system, it does not do specific things, it only two kinds of behavior, one is baseaction, the other is altaction, to understand the two actions, you can consider the gun. Gun is a weapon that can be both melee and can be far from war, shooting is

An improved method for processing uC/OS-II Task Stack
Abstract:In the μC/OS-II kernel, different tasks use independent stack space, the size of the stack is defined by the maximum stack depth required by each task, this method may cause a waste of stack space. This article describes how to share the continuous storage space among multiple tasks in RTOs as a task stack method, and compares the advantages and disadvantages of the two and their applicabi
It seems that android is very popular now. I really want to learn Android, but Android is also a Linux kernel, that is, to build a Java virtual machine on the Linux kernel and execute Java programs (my understanding is not necessarily correct ), so it's good to learn about Linux... Haha.

Reentrant function
The last time I talked about the reentrant function, what is the reentrant function? A reentrant function is simply a function t
3rd-bit bit3 in osrdygrp, assume that the rightmost bit0 is 0th bits. Similarly, if the value of osrdytbl [3] is binary 11100100, the value of osunmaptbl [osrdytbc [3] is 2, that is, 2nd bits. Therefore, the task priority is equal to 26 (3*8 + 2 ). Use this priority value. Query the task control block priority table ostcbpriotbl [] to obtain the task control block OS _tcb pointing to the corresponding task.
