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
}

Hacker_Disassemble_Uncovered
Kris Kaspersky对他的书做过一个总结，以下是关于这本书《黑客反汇编揭秘》的：
Солон是一家不大的出版社，里面氛围很是温馨，团队关系密切、融洽，只是能力尚有不够。我可不会满足于此。我打开了美国市场, 与出版社A-LIST进行了合作。在“讲述基本原理”的指导思想下以紧凑的篇幅编写并翻译了这本后来成为best-seller的书《HACKER DISASSEMBLING UNCOVERED》，这是我到目前为止卖得最好的书。我还客串了一把翻译技术顾问，但是我还没试过自己用英语进行写作。(Kris Kaspersky his book made a summing up, the following about this book are a " hacker disassembly Secret" in: Солон is a small publishing house, which was a warm atmosphere, the team close and harmonious, but the capacity still not enough. I can not meet this. I opened the American market, with the publishing house A-LIST cooperation. At " about the basic principles of" the guiding ideology of the space under the compact prepared and translated it later became the best-seller book of the " HACKER DISASSEMBLING UNCOVERED" , This is my best-selling book so far. I also had a guest Translate technical adviser, but I have not tried to carry out their own writing in English.)
