软件分为五块：主程序中的初始化模块、换相子程序模块、电流调节、速度调节子程序模块，定时器中断程序模块。
The system software involves five main modules: initialization module, phase-changing module, current-regulating module, speed-regulating module and timer interrupt module.
本文通过分析通用异步通信器件的工作原理，给出了一种利用单片机的定时器中断程序实现异步通信的方法，并在实际工程项目中得到了应用。
Based on the principle of UART, a software method has been presented for asynchronous communication by using interrupt program of timer, and has been implemented in an application project.
在硬件设计的基础上，文中对系统软件设计中的检测主程序、A/D转换子程序、定时器A中断子程序和液晶显示子程序的设计进行了系统性介绍。
On the base of the hardware design, this paper introduces the main program, A/D convert subprogram, Timer A abruption subprogram and liquid crystal display subprogram of software systematic.
它也有可能是病态的软件程序，以用于其他目的，定时器，计数器和中断率的变化。
It is also possible for an ill-behaved software program to use the timer-counter for another purpose and change the interrupt rate.
然后，直到发生定时器中断且调度程序在内核态被激活，进程1才恢复在用户态下执行。
Process 1 then resumes execution in User Mode until a timer interrupt occurs, and the scheduler is activated in Kernel Mode.
实验目的目的：掌握定时器t0、T1的方式选择和编程方法，了解中断服务程序的设计方法，学会实时程序的调试技巧。
Aim Objective: to master the timer T0, T1 of the mode selection and programming methods, to understand the design method of the interrupt service routine, and learn skills in real-time debugging.
