PWM-ULN2003A
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
}
)

单片机虚拟串口仿真图,里面有虚拟串口软件和串口调试助手,还有用proteus进行的仿真图,不用开发板一样进行仿真,只能说proteus太强大了。只要你想不到的,没有他做不到的!(Virtual serial port emulation chip chart, which has a virtual serial port software and serial debugging assistant, as well as performed with proteus simulation map, not the same simulation development board can only say proteus too strong. As long as you think, no he can not do!)

本文讲述了细分驱动技术的原理,重点介绍了细分驱动控制系统的设计方法,设计了一套传统细分驱动系统的设计方案,在此基础上,本文进一步介绍了L297、L298两块芯片,采用这两块芯片构成步进电机的驱动电路,应用DAC0832实现D/A转换,采用精简指令集单片机AVR作为脉冲产生器,对步进电机的工作过程进行控制,最终组成电机细分数可选的驱动控制系统。(failed to translate)
