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
}
)

1. 本研究利用 PCA 对可见-近红外(450~1 000 nm)、可见光(450~780 nm)和近红外(780~1 000 nm)光谱区域的苹果高光谱图像数据进行降维,获得 PC 图像,通过对 PC 图像进行分析,确定可用于分割损伤和正常区域的有效光谱区域,对比分析几个光谱区域的 PCA 的效果。(but currently no practical system for detecting blood spots and
dirt stains exists. In order to obtain maximum throughput, processing speeds
of over 85,000 eggs per hour are common. The demanding requirements
placed on the human workers result in two types of grading errors)

这是有关pwm的控制,可以控制它周期的长短来控制灯的亮度,还可以控制它自动调光。(This is the control of the pwm, the length of the cycle it can be controlled to control the brightness of the lights can also control the automatic dimming.)
