高精度电压表(24bit) VB源程序,简单修改可实现多量程(precision voltage (24bit) VB program, a simple change can be realized more range)

计算太阳位置，通过公式！用单片机编译程序！(Calculate the position of the sun through the formula! Microcontroller compiler!)

利用单片机（STC89C52）为核心结合机械按键、数码管以及稳压器件等电子元器件组装了一个数字时钟，可以实现精准的计时以及修改等功能；(The combination of mechanical buttons, digital tube, and electronic regulator device the microcontroller (STC89C52) as the core components assembled a digital clock, and can achieve precise timing and modify functions )

这个是我写的单片机PWM脉冲调制程序，希望对初学者有点点帮助！(This is what I write microcontroller PWM pulse modulation program, hope for beginners who are little help)

2相四线八拍步进电机程序，可以正转反转，加减速(2 phase four line 8 stepper motor)

ADS1258开发，程序源代码，还要20字 好恶心(ADS1258 development, source code, but also the word disgusting 20)

2.4G研发详细文档，对没有无线基础的同学非常有帮助！(2.4G development with the document, very helpful to students based on no wireless! )

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 } )
