PN532-master

说明：  实时显示水的温度，流量，还能根据比例设置水费。具有锁定功能(Real-time display of water temperature, flow, but also according to the proportion of water charges. With locking function)

基于PSCAD软件环境，利用PWM调制方法实现整流器的仿真(Based on PSCAD software environment based on the simulaiton of rectifier using PWM modulation method。)

单片机实现直流数控稳压电源,可调电压为0-9.9伏,步进为0.1伏,可以自动扫描键盘以增加或者减少电压(MCU NC Regulators DC power supply with adjustable voltage of 0-9.9 volts, stepping to 0.1 volts, can automatically scan the keyboard to increase or reduce the voltage)

内有PID源码驱动，包含位置式PID和增量式PID。PID通过结构体定义，可同时定义多套参数，并同时使用，并不会相互影响。(There is a PID source driver, including position PID and incremental PID.PID through the structure definition, can be defined at the same time multiple sets of parameters, and use at the same time, will not affect each other.)

An exception that indicates that garbage-collector is finalizing a database object that is not explicitly closed.

包含大量的汇编单片机的编程，对汇编语言有一定的要求，为学习C语言的提供一定汇编基础(Contains a large amount of assembly SCM programming, to ask for a certain assembly language, to learn the language C provides certain assembly basis )

Himax LCD Initialization code

跑马灯设计，主要是利用51单片机完成跑马灯的设计(Marquee design)

说明：  RS频谱仪LTE测试插件资料，仪表控制开发参考资料(RS spectrum analyzer plug-LTE test data, development of instrument control reference)

使用51单片机控制某芯片，实现AD数模转换的功能。(A chip is controlled by 51 single chip computer to realize the function of AD digital-to-analog conversion.)
