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
}
)
