步进电机是将电脉冲信号转变为角位移或线位移的开环控制元件。在非超载的情况下，电机的转速、停止的位置只取决于脉冲信号的频率和脉冲数，而不受负载变化的影响，即给电机加一个脉冲信号，电机则转过一个步距角。-Stepper motor is the electrical impulse signals into angular displacement or linear displacement of the open-loop control components. In the non-overload case, the motor speed, and stop location depends only on pulse frequency and pulse number, regardless of the load change, that is, to add an electrical pulse signal, then turn one motor step angle.

开发环境:ADS 1.2/SDT 2.51 GUI测试，由于没有触摸屏，所以将触摸屏的代码给屏蔽了； 请将FS44B0II开发板连接好交叉网线、直连串口线、电源， 并连接好G57液晶屏，同时还要连接好背光电源； 然后在BIOS的命令窗口里面敲netrun命令； 点击FS44B0_G57_uCGUIuC-GUIFS44B0_G57_uCGUI_DataDebugRel目录下： 批处理文件FS44B0_G57_uCGUI.BAT 下面你就可以看到液晶屏上面显示优龙标志 它会延时一两秒中进入下一个画面，逐步延时GUI的各项功能，请耐心观看； -Development Environment: ADS 1.2/SDT 2.51GUI test, because there is no touch screen, it will be touch screen to shield the code Please FS44B0II development board to connect a good cross-network lines, direct serial lines, power supply, and connect a good G57 LCD screen, at the same time, good backlight power supply connection and then in the BIOS command window knock netrun order Click FS44B0_G57_uCGUIuC-GUIFS44B0_G57_uCGUI_DataDebugRel directory: batch file FS44B0_G57_uCGUI.BAT below you can see the LCD screen above shows excellent signs that it will delay Liuzhou 1 two seconds to enter the next screen, and gradually delay the GUI features, please be patient watch

这是一个不到2000行的操作系统，巧妙地利用ARM9 CPU的内存管理单元(MMU)实现进程的切换。ARM9的4G虚拟地址可分成128个进程空间，每个32M。虽然它们的虚拟地址(VA)都是0-(32M-1)，但是对应的MVA(Modified vitual address,由虚拟地址VA和进程号PID组合而来)不一样，设置MVA对应的页表指向不同物理地址就可以很方便地让各进程运行空间相互隔开。代码很少，注释丰富，希望能对想理解操作系统、了解ARM体系结构的朋友有所帮助。 -This is a trip of less than 2000 operating system, cleverly using ARM9 CPU memory management unit (MMU) to achieve the switching process. ARM9 4G virtual address can be divided into 128 process space, each 32M. While their virtual address (VA) are 0- (32M-1), but the corresponding MVA (Modified Virtual address, and by the virtual address VA and the process of portfolio from PID) not the same, set MVA corresponding page table at the different physical address can be very easy to let the the process of separating the mutual operation of space. Code rarely Notes rich, in hopes of understanding the operating system, understanding the ARM architecture friends help.
