51单片机考勤系统下位机程序，可以配合上位机软件实现考勤功能，将hex文件下载到51单片机即可使用(51 MCU control procedures can be achieved with the PC software attendance function, the hex file into the microcontroller 51 can be used)

积分器的一种实现方法：每级积分器都是一个反馈系数为1的单极点IIR滤波器, 其传递函数为:(An implementation of an integrator: each stage integrator is a single pole IIR filter with a feedback factor of 1:)

单片机设计，设计俄罗斯方块，包含主程序、工程文件等，欢迎下载(MCU design, design tetris, including the main program, project files, etc., welcome to download)

hs108单片机控制两个MC44BS373CA实现载频为30MHz和50MHz的I2C通信(hs108 MCU control two MC44BS373CA achieve carrier frequency of 30MHz and 50MHz of I2C communication )

对电压、电流的有效值进行计算函数，计算有效值的周期可进行设置。(RMS calculation function)

说明：  stc8a8k64s单片机的示例程序，适合初学者好好研究学习(Stc8a8k64s MCU example program, suitable for beginners to study)

一种占用很少资源的多事件操作系统，应用在M128上，极容易扩展到其他微控制器(A few more resources occupied events in M128 operating systems, applications, extremely easy to expand to other micro controller)

STM32单片机 串口bootloader ，IAP源码。测试过了。方便调试使用。方便商用升级代码，串口实现，方便改成USB接口(STM3210X uart bootloader IAP)

可以通过stm32控制ad8370的增益(Control the gain of AD8370 with stm32)

说明：  STM32F103串口函数,接收,发送,经过测试,完全可用(Serial port function)
