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!)

cc2500的头文件。寄存器的设置使得传输速率为芯片的最大值250kbps，可支持6通道1k的采样率。(cc2500 header file. Register settings for the chip transfer rate makes the maximum 250kbps, can support 6-channel sampling rate of 1k.)

单片机AD功能实例，使用1602显示电压(SCM AD function example, the use of 1602 shows the voltage)

MSP430FR57x Demo - Toggle P1.0 using software Description: Toggle P1.0 using software. ACLK = n/a, MCLK = SMCLK = TACLK = default DCO = ~625 KHz(MSP430FR57x Demo- Toggle P1.0 using software Description: Toggle P1.0 using software. ACLK = n/a, MCLK = SMCLK = TACLK = default DCO = ~625 KHz)

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.)

AT89S52键盘程序,这是一个变频器的键盘驱动程序，简单，可靠，芯片为51单片机(one simple progrem for 51,if you like ,you can use it freely.)

单片机HUFFMAN压缩算法的研究与实现，有在单片机上进行开发的同学可以下载看看！(Huffman compression algorithm Singlechip Research and Implementation, has carried out development in SCM students can download to see!)

HT66F50单片机完整程序，测试通过。(HT66F50 SCM complete program test.)

利用PID算法控制PWM输出电压，实现串联型数控电源，通过键盘输入控制期望电压(PID algorithm to control the use of PWM output voltage to achieve tandem CNC power, through the keyboard input control voltage expectations)
