反射式血氧（SPO2）计算

说明：  基于51单片机红外遥控智能小车（原理图、PCB、遥控器控制程序、实物图）(ntelligent car based on 51 microcontroller infrared remote control (schematic diagram, PCB, remote control program, physical map).)

基于IAR平台来开发MSP430单片机，制作四旋翼遥控器的代码。(Based on IAR platform, MSP430 MCU is developed and the code of Four-rotor remote controller is made.)

将每2片74595做级联，然后再将级联之后的所有时钟线与数据再并联在一起最后对每一组的锁存控制线做单独控制.(Application to do a project, the more I/O, applied to the 74,595 to do the extension, but you want to mount multi-chip 74595, is bound to have a lot to use the I/O port, in order to solve this problem, I will be every 2 sheet 74595 do cascade, and then cascade after all the clock line and the data in parallel and then together (i.e., all 74595 communal clock and data lines, it only occupies two I/O port lines) Finally, for each group latch control lines do individually controlled (equivalent to Chip Select), so that a hardware circuit by a great degree of simplification, both procedures can also share a driving subroutine 74595, to control the type of lock inventory control line, serial data is sent to the port 74595 cascade module. As a result of the hardware and software have a large degree of optimization.)

基于EDA技术中的对LED扫描电路的实验，程序能成功运行，能直接在开发板上看实验结果(EDA-based LED technology to scan the experimental circuit, the program can run successfully, can see directly in the development of on-board results)

高超声速飞行器课程大作业，建立了六自由度模型，并分别采用极点配置、LQr和H无穷控制仿真 (The hypersonic vehicle courses operations, the establishment of six degrees of freedom model and were used pole placement of LQr and H infinity control simulation)

说明：  基于STM8的DHT11温湿度计，单总线通讯(DHT11 Thermometer and Humidimeter Based on STM8, Single Bus Communication)

这是我看了《十天学会单片机》（郭天祥的教程）第十课时写的，综合了矩阵键盘，串口通信，数码管 动态显示，定时器中断的简单时钟程序。用51电子网买的298元80C51单片机学习板 （http://www.51dz.com/n.asp?id=12519&i=xie343706382）测试时请将p1口用排线连到CZ2上，控制8位 数码管用。P0口用来检测矩阵键盘的，P3.0和P3.1是串口通信用，控制74H164N芯片段选8位数码管。 数码管显示内容为时分秒个两位，按下K16为设置按钮，按一下调节秒数，再按一下调节分钟，再按一 下调节小时。再按下退出，走时。调节时按K1至K10分别代表0到9。 我的QQ343706382，希望有喜欢单片机的朋友。和我联系。(This is what I read "10 days Singlechip Society" (郭天祥tutorials) written by the tenth class, integrated matrix keyboard, serial communications, digital tube dynamic display, a simple clock timer interrupt procedures. Electronic network with 51 of 298 yuan to buy 80C51 single-chip learning board (http://www.51dz.com/n.asp?id=12519)

基于C51单片机的1602液晶屏显示时间，实现计时功能(Based on 1602 C51 LCD shows time, realize the timing function)

xlinx公司关于xaui xgmii的讲解和产品介绍(xlinx company on xaui xgmii explanations and Products)

近段时间闲来无事做了一款AV和HI-FI两用的前级，采用音量音调处理芯片PT2322完成音量音调的处理，支持六声道音量0~15分贝可调，高中低音支持-7db~+7db可调，总音量支持0~79分贝可调，步进为2分贝每次，并且具有静音、3D和直通功能，不论是在听音乐还是在看电影两不误；采用pt2323实现音源输入选择和2声道转换成6声道的功能，支持四组普通立体声输入和一组DVD六声道输入，并且能够将四组立体声其中的任何一组转换成六声道，即使是用VCD看普通碟片时也能欣赏到有如DVD一样的环绕音效。由于PT2323和PT2322支持I2C总线控制，利用89c51对其进行控制，PCB板连线方便，控制简单。本板除了以上功能外，还特留有一个输出口，用来控制后面所接的功率放大模块的电源的关断，以实现遥控开关机，静音时也将功率放大模块的电源模块关断，以实现节能的目的。本电路还有一个重要特点，整个电路采用单5V电源供电，接口简单，连线方便，便入摩机用。人对电路操作主要有两种方式，一是通过键盘来进行控制，二是通过配有的红处的遥控接收头来控制，遥控器可选市面上很容易买到的由TC9148型的遥控器即可。本人提供少量PCB板，供爱好音响和单片机的同行做实验， 如有需要也可提供全套散件或成品板。 (err)
