linux下的jtag仿真器程序，可使用在arm7（44b0，4510，2410等）和arm9上面，可以烧写flash 39lv160等，再不用两个系统不停重启了。-the JTAG Emulator procedures, the use of the ARM7 (44b0, 4510,2410) and arm9 above, 39lv160 burning flash, no longer have to keep two systems resumed.

电机是使机械能与电能相互转换的机械，直流电机把直流电能变为机械能。作为机电执行元部件，直流电机内部有一个闭合的主磁路。主磁通在主磁路中流动，同时与两个电路交联，其中一个电路是用以产生磁通的，称为激磁电路，另外一个是用来传递功率，称为功率回路或者电枢回路。-Motor is to convert between mechanical energy and power of machinery, the DC to DC motor into mechanical energy. Executive Yuan as the mechanical and electrical components, DC motor inside the main magnetic circuit has a closed. The main magnetic flux flowing in the main magnetic circuit, while cross-linked with the two circuits, one circuit is used to generate magnetic flux, called the exciting circuit, another one is used to transfer power, known as the power circuit or the armature circuit .

最近网上找到并修改通过的mega8源代码，包括1602四线驱动、ADC、串口通信、3个io口连接22个按键、PWM、时钟等-Recently adopted by the Internet to find and modify the source code mega8, including the 1602 four-lane drivers, ADC, serial communication, 3 io port to connect 22 buttons, PWM, clock, etc.

该源码继承了大量功能控件，如定时器、按键、串口通讯等，并已成功嵌入到产品中，可以节省大量时间。-the source inherit a lot of control functions, such as timer, keys, serial communications, and has successfully embedded into products, can save a lot of time.

基于ARM Cortex-M3内核的STM32F103RBT6处理器为核心构建柔性锁相环的硬件实验平台，在STM32中模拟出三相电源电压，并在子程序中实现了SRF-PLL、DDSRF-PLL与DSOGI-PLL三种锁相环，通过IO口并行输出锁相结果，再通过DAC转换为可观测的模拟信号。源码包中包含了软件工程与硬件电路原理图两部分。
