arm9软中断的一个例子。。。。想要了解swi软中断详细处理过程的朋友可以下(ARM9 soft interrupted an example. . . . Want to learn the soft interrupt SWI detailed friends can deal with the process under)

说明：  01.03.05.06码进行读写，实现触摸屏按钮和数字输入通过485在实验板上显示数字，和点亮LED(01.03.05.06 code for reading and writing,)

对OLED进行显示，分别用IIC的以及SPI的来进行测试(Display OLED and test it with IIC and SPI respectively)

采用stm32构成的示波器。采用STM32高性能ARM处理器作为核心控制芯片，能够满足TFT彩色波形显示，数字插值算法处理等。通过采用高速AD和FIFO器件，实现了高采样率，宽频带的技术要求。实验室测试结果表明本文的设计是正确的，各项指标均达到设计要求。(osc scope degin by stm32)

说明：  ADI 公司的高精度、三相电能测量芯片 ADE7878 进行电能计量，包括有功、无功和视在电能的计量。实现了电压、电流有效值测量，功率因数测量，以及电压跌落、过压和过流检测、相序检测等电能质量测量功能(ADE7878 goes beyond Class 0.2 Accuracy specification for Active Power Improves Active energy accuracy over line frequency to 0.1% for +/-10% line frequency)

使用stm32f103读sd卡的文件系统中的音乐文件，并解析播放的程序。(STM32F103 is used to read the music files in the file system of SD card and parse the playing program.)

STM32 IAP升级程序　已通过硬件验证，另有APP程序，需要的请联系！(STM32 IAP upgrades)

国嵌mini2440实验代码，视频实验源代码4部分(Mini2440 development board based on the video test source code Part 4)

说明：  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.)
