ADDERS USING DIFFERENT COMBINATIONS

利用ULN2003A进行驱动，产生PWM波，里边有照片，可供参考，通过本例程了解PWM 的基本原理和使用 (#include <reg52.h> unsigned char timer1 sbit PWM=P1^2 void system_Ini() { TMOD|= 0x11 //PWM TH1 = 0xfe //11.0592 TL1 = 0x33 TR1 = 1 IE =0x8A } main() { system_Ini() while(1) { if(timer1>100) timer1=0 if(timer1<30) PWM=0 else PWM=1 } )

单片机自学手册，内容很全面且使用，感兴趣的可以下来看看(SCM self-study manual, which is very comprehensive and uses, interested can look down)

说明：  LLC电路的PI闭环程序，实现电流闭环，非常稳定经过实测，没有问题(The PI closed-loop program of LLC circuit realizes the current closed-loop, which is very stable. After actual measurement, there is no problem)

组态王在实际应用中，温度测量与报警控制程序设计(Kingview in practical application, temperature measurement and alarm control program design)

该程序实现4~20mA直流电流的采集，并通过485通信上传，通信协议为modbus rtu(4~20mA DC current measure)

ADC C++ for 9S12XS128 FREESCALE

说明：  32控制的防尾随门，主要应用于银行安检防盗门(32-controlled anti-tail door)

STM32转换ADC值并通过LCD1602进行显示(STM32 converts ADC values and displays them through LCD1602)
