AT89C51SND1C方案mp3资料包括源程序与原理图(AT89C51SND1C program information, including source code and mp3 schematic)

基于430g2233的温度程序，有18B20和PT1000，两种传感器(The temperature program based on 430g2233)

STM32 SPI口的应用例程，可是设置成主模式或者从模式。(STM32 SPI routine application of the mouth, but set to master mode or slave mode.)

c8051 mcu 单片机 adc程序。全部c8051适用(c8051 adc)

LCD液晶显示程序，在AT89S52上运行成功，其也可以用于其 他的处理器(LCD liquid crystal display program, run on AT89S52 is successful, it can also be used for the processor)

说明：  用mcs-52系列单片机实现等精度频率测量，T1引脚接被测TTL信号，晶振22.1184MHz，对任何频率都可以实现很高精度的测量（精度<1 )，结果从串口字符串输出，波特率115200，可以用串口调试器观察结果.(With mcs-52 family of single chip and other precision frequency measurement, T1 pin then measured TTL signal, Crystal 22.1184MHz, any frequency can be achieved very high accuracy of measurement (precision<1 ), the result string from the serial output , baud rate 115200, serial debugger can observe the results.)

随机调制信号下的模拟ppm，基于SVPWM的三电平逆变的matlab仿真，在matlab R2009b调试通过。( Random ppm modulated analog signal under Based on SVPWM three-l)

以前电子竞赛时写的M3 ARM控制TFT液晶显示正弦波波形可以连贯的左移，没有闪烁感，我还写了一个也是正弦波左移，只不过有一点闪烁，我也上传了，你们需要可以找一下！(Writing contest before the electronic control M3 ARM TFT LCD sinusoidal waveforms can be coherent left, no flashes, I also wrote a sine wave is left, just a little flicker, I also uploaded, you need to be able to Get it!)

ST7565是一款点阵液晶驱动芯片，它具有并行与串行（SPI）两种接口.(ST7565 is a dot matrix LCD driver chip, it has the parallel and serial interface (SPI) two.)

基于51单片机的信号发生器 四种波形显示 有级调频(Based on 51 single-chip signal generator)
