This digest from my my book fixing "embedded Linux driver template explaining and project practice"Initially it seems that Linux device driver development involves a lot of content, and the need to achieve a wide range of drivers, in fact, after a period of time to drive back looks like the main points are:(1) Classification of the drive, first summed up as which

Research on Low Power strategy of Embedded Linux Abstract: Power consumption is a very important performance indicator for embedded devices. After the hardware design and selection, the power consumption level depends greatly on the software design. In view of the increasing application of lioux in embedded devices, s

What is an embedded system? The mobile phone is a typical embedded system.Embedded computers are used much more than PCs. In fact, recent market data show that the microprocessor chip used by personal computers accounts for only 2% of the annual market share. The average room has at least dozens of embedded computers, even without a personal computer.What is real

A typical Desktop Linux system includes three main software layers: Linux kernel, C library, and application code. The kernel is the only layer that can fully control the hardware. The kernel driver represents the session between the application and the hardware. On top of the kernel is the C library, which is responsible for converting posix api into a form that can be recognized by the kernel, then callin
