基于STM32的嵌入式操作系统程序设计及实现毕业设计.doc

摘 要 STM32硬件平台及μC/OS-II的移植需求；最后，在μC/OS-II上开发LCD，LED，按键KEY等应用程序，并对多任务系统调试分析。主要研究结论如下： （1）μC/OS-II操作系统主要分为任务管理、内存管理和时间管理三大部分，其间通信是通过消息队列和消邮箱。 （2）μC/OS-II移植主要在OS_CPU.H，OS_CPU_C.C，OS_CPU_A.ASM三个文件中，涉及到数据类型、堆栈、中断定义和任务切换等。 （3）应用程序设计优先级分配要合理，硬件平台初始化模块化处理。 关键词：嵌入式系统；μC/OS-II移植 Abstract With the progress of science and technology constantly, advanced industrial production to more complex, the operating system μC/OS-II is efficient, stable, reliable, energy saving system, widely used in the security, and consumer electronics. And based on the STM32 architecture Cortex-M3 framework is a superior cost-effective new microprocessor, μC/OS-II transplantation to STM32 can play its efficient performance, thus in social production and create a lot of useful and affordable electronic product, bring convenience to our lives. This article main research content is μC/OS-II operating system theory analysis, method of transplantation, application design and debugging of the simulation implementation. First of all, the theoretical analysis of μC/OS-II, research the actual application and system structure; Second, analysis of STM32 hardware platform and the demand μC/OS-II transplantation. Finally, on the μC/OS-II development of LCD, LED, button KEY applications, and analysis of multitasking system debugging. Main research conclusion is as follows: (1) μC/OS-II operating system consists of three major task management, memory management and time management, in which communication is through the message queue and email. (2) μC/OS-II transplantation mainly in OS_CPU_C.C, OS_CPU_A.ASM file, OS_CPU.H, three involves the data type definition and task switching etc, stack, interrupt. (3)The application design to the allocation of priorities, initialize the modular processing hardware platform.
