Bare metal handling of eint4 interruptions This is the bare metal processing of eint4 interrupt based on S3C2410. When the interrupt occurs, the LED light is reversed. The following is a circuit diagram. The external key is connected to the eint4 pin of the CPU. That is, pressing the key causes an interruption. Accor

What is the difference between Iphone6 mobile phone contract machine and bare metal? For the contract machine, I believe that everyone will be unfamiliar, in many outdoor billboards, you can see a variety of very attractive "0 yuan buy machine", advertising slogans, the contract machine is actually the network operators to introduce mobile phone calls + mobile bundled marketing methods. In layman's terms,

I have been using Ubuntu for two years. From dapper-6.06 to the current hard-8.04 (it took only one month ). At the beginning, I felt that Linux technology was booming. Progress is very slow after a period of time. I think I am a beginner at the cainiao level. I also think Ubuntu masks many Linux things. I only use its shell, and then press the mouse to beat my life. . In addition, you don't even need to execute commands to use Ubuntu to install everything you have just created. Later, I learned
