ov9655 datasheet user guide(ov9655 pdf datasheet for user guide including V4 and V5 settings. At the same time it include the timing fig and register configure information)

超声波测量距离，显示在液晶1602上，经测试，测量距离为3cm到6m，反应很灵敏。(Ultrasonic distance measurement displayed on the LCD 1602, and tested to measure the distance of 3cm to 6m, reaction is very sensitive.)

说明：  复制其中的“UV4.CDB”文件，复制到KEIL4的“UV4”文件夹中；(Copy the "uv4. CDB" file to the "uv4" folder of keil4;)

基于90s2313的计算机并口频率计，有图纸和源代码(Parallel computers based 90s2313 frequency meter, there are drawings and source code)

说明：  该抢答器供不多于4个参赛队或者个人的抢答比赛场合使用。每个参赛队的座位前 安装1只抢答按钮开关（用板上的S9、S10、S11、S12）和一个信号灯（D4、D5、D6、D7）。 主持人座位前装一只复原开关（板上S3）、1只蜂鸣器（板上BUZ1）和一个抢答器工作状态 指示灯（D10),每当主持人口头发出号令之后.哪个队先按下座位上的按钮开关,该座位的信 号灯就先被点亮,同时封锁其他按钮开关的活动.并且熄灭主持人座位上的状态指示灯和发出 三声类似于电话振铃的提示声,以声明此次抢答动作已经完成.在主持人确认后,按下复原按钮 ,状态指示灯重新点亮,并且同时发出"笛-笛-"声,为下一次抢答作好准备.(the Responder for up to four teams or individuals in the use of Responder competition occasions. Every team installed the seats before a Responder button switch (with the board S9, S10, S11, S12), and a signal (D4, D5, D6, D7). Moderator seats installed before a recovery switch (S3 board), a buzzer (BUZ1 board) and a Responder work status indicators (D10), whenever the moderator after oral orders issued. Which team first press of a button switches, the seat lights were lit on the first, while the blockade of the other button to switch activities. Moderator seats and extinguished the lights and the state issued three sound similar to the telephone tips ringing sound, in a statement this Responder action has been completed. the presenters confirmed? recovery button, status indicators re-lit,)

Semi-active fuzzy control for seismic response reduction

基于PSCAD的双环两电平仿真电路，对于理解三电平原理非常有用。(Based on PSCAD bicyclic two-level circuit simulation, very useful for understanding the three-level principles.)

stm32 串行flash 挂fatfs(fatfs for stm32 and spi flash)

自抗扰控制的源码，可以用在无人机控制中，也可以在各种场合替代PID(the source code of ADRC)

基于ARM的芯片多数为复杂的片上系统,这种复杂系统里的多数硬件模块都是可配置的,需要由软件来设置其需要的工作状态。因此在用户的应用程序之前,需要由专门的一段代码来完成对系统的初始化。(ARM-based chips, most of the complex system on chip, where the majority of this complex system can be configured hardware modules are required by the software to set up the working status of their needs. Therefore, the application before the user needs from the special section of code to complete the initialization of the system.)
