华邦的W996[78]cf芯片组的摄象头驱动程序，对开发USB摄象头的同行很有帮助。(The Winbond W996 [78] cf chipsets摄象头driver, on the development of USB摄象头peer helpful.)

OBD-II source code for TL718 簡易OBD訊號控制(OBD-II source code for TL718)

说明：  单片机位移控制流水灯，C放言和汇编语言，proteus仿真(SCM displacement control water lamp, C release and assembly language, proteus simulation)

说明：  嵌入式之使用STM32F429完成锁相环放大器的设计，包含C语言源码。(PLL Amplifier completed by STM32F429.)

增量pid的阶跃跟踪程序，适用于执行机构是控制量的增量的场合(Pid incremental step tracking procedure is applied to the implementation of the incremental volume control occasion)

名称：门禁模拟 模拟现实中门禁系统，可以输入密码进入也可以呼叫住户，再由住户按下开门按键 实现改密码功能，密码保存在24c02中能保证掉电不丢失密码。八个LED灯分别代表 8家住户，其中开门按键为共用，还带有忘记密码恢复按钮，模拟恢复出厂设置， 显示部分为LCD1602。程序共分为3种模式，分别为 等待输入 密码修改 呼叫住户 3种模式，其中等待输入是主要状态，所以在进入密码修改 呼叫住户模式后如果 长时间没有操作能自己切换到等待输入模式。(Name: Access Analog Simulating real access control system, you can also enter a password to enter the call households, again by pressing the open button households Implement change password function, the password stored in the 24c02 can guarantee non-volatile password. Eight LED lights represent 8 households, which opened the door keys are shared, but also with forgotten password recovery button, analog restore factory settings, Display part LCD1602. Program is divided into three modes, namely, waiting for a password to modify call households 3 modes, which is the main input wait state, so call households entering the password change mode if Their long time operation can be switched to the standby input mode.)

利用Keil C51 和LabVIEW编写程序实现PC与单片机串口通信。 设计任务 PC通过串行口将数字（00 ，01 ，02，03... ，FF，十六进制）发送给单片机，单片机收到 后回传这个数字，PC接收到回传数据后显示出来，若发送的数据和接收到的数据相等，则串 行通信正确，否则有错误。启始符是数字00，结束符是数字 FF。(Use Keil C51 and LabVIEW programming to achieve PC serial communication with microcontroller. Displayed after the PC via the serial port design task digital (00, 01, 02,03 ..., FF, hex) is sent to the microcontroller, the microcontroller receives return this figure, PC receives the return data , if the data sent and received data are equal, the serial communication is correct, otherwise an error. Startup character is a number 00, the end of the character is a number FF.)

STM32+DS3231+TM1640驱动数码管，显示年月日星期时分秒温度。已经跑了好几天，运行良好(STM32+DS3231+TM1640 display year, mouth,date,week,hour,minute,second,and temp.)

说明：  当温控开关打开时，若测得环境温度大于设定温度，则继电器吸合 启动电机工作；若测得环境温度小于设定温度，则继电器释放， 电机停止工作；(When the temperature control switch is turned on, if the measured ambient temperature is higher than the set temperature, the relay will suck in. Start the motor; if the measured ambient temperature is less than the set temperature, the relay will be released. The motor stopped working.)
