ARM-series-Cores

arma和gm模型，根据论文写得，效果和论文结果一样，可以参考(arma and gm model, based on written papers, and papers effect the same results, you can refer to)

基于ARM7的开发板的外部存储器接口程序，文件里有程序的详细注释，对与在此基础之上的二次开发非常方便(based on the ARM7 development board external memory interface, document the procedures detailed notes, right and the basis of this second development is very convenient)

用Stm32f103当示波器，具有分析输入波形功能，同时又能输出波形自己花了将近一个月编出。(When using Stm32f103 oscilloscope, with analysis of the input waveform function, at the same time can output waveform spent nearly a month to write themselves.)

at91sam7a3的pwm学习例程，运行于iar开发环境，调试通过(at91sam7a3 pwm learning routines, running in the the iar development environment, debugging through)

系统中采用了电压反馈闭环，单片机通过内部软件产生一路SPWM控制信号，然后经过逻辑门变换电路变换成逆变全桥所需的四路驱动信号，再经专用驱动芯片TLP250隔离放大后，分别加到逆变全桥四个IGBT的栅极，进行驱动控制。(The voltage feedback closed loop is used in the system, and the single chip microcomputer generates all the SPWM control signal through the internal software, then transforms the four-way drive signal required by the logic gate transformation circuit into the inverter full bridge, and then adds to the gate of four IGBT of the inverter full bridge after the special drive chip TLP250 isolation and amplification, and carries on the drive control.)

采用VS1003方案的STM32 MP3播放器完美版，包含FAT文件系统、TFT液晶操作、图片文本解码等(Program using VS1003 perfect version STM32 MP3 players, including FAT file system, TFT LCD operation, picture text decoding)

立宇泰４４Ｂ０所有测试源代码，使用中请根据自己板上资源情况作相应修改(Thai 44B0-up testing of all source code, please use the resources according to its own board of the amended accordingly)

说明：  ADControl.SchDoc--电路原理图、MCUADforC--Keil C51程序、MCUAD--汇编程序(ADControl.SchDoc-- circuit diagram, MCUADforC- Keil C51 program, MCUAD- assembler)

说明：  STM32 SPI驱动LCD,在网上down下来了一份串口驱动，更改成自己需要的SPI驱动，自己调试验证通过了。(STM32 SPI LCD driver)
