Embedded computer systems permeate all aspects of our daily lives.
Alarm clocks, coffee makers, digital watches, cell phones, and automobiles
are just a few of the DEVICES that make use of embedded systems. The
design and development of such systems is unique, because the design
constraints are different for each system. Essential to the development of
an embedded system is an understanding of the hardware and software
used for development.
TION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
WARNING!
Although the AD7008 features proprietary ESD protection circuitry, permanent damage may
occur on DEVICES subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.
This example application is a collection of Flash Lite do s and don ts from the
usability point of view. The application contains real examples and animations
of static examples that help you to see problematic issues in real life on a
Nokia device. The application is optimized for DEVICES with the resolution 170 x 208
pixels used in portrait mode.
This example application is closely related to the document Flash Lite: Visual Guide,
and it is highly recommended to read the document before going through this example.
FLASH文件系統(tǒng)的源碼，F(xiàn)lash memory is a nonvolatile memory, which allows the user
to electrically program (write) and erase information. The
exponential growth of flash memory has made this technology
an indispensable part of hundreds of millions of electronic
DEVICES.
Flash memory has several significant differences with volatile
(RAM) memory and hard drive technologies which requires
unique software drivers and file systems. This paper provides
an overview of file systems for flash memory and focuses on
the unique software requirements of flash memory DEVICES.

Cypress Semiconductor makes a variety of PLL-based clock
generators. This application note provides a set of recommendations
to optimize usage of Cypress clock DEVICES in a
system. The application note begins with recommended termination
techniques for clock generators. Subsequently, power
supply filtering and bypassing is discussed. Finally, the application
note provides some recommendations on board
layout.
Universal Serial Bus (USB) is a communications architecture that gives a personal
computer (PC) the ability to interconnect a variety of DEVICES using a simple four-
wire cable. The USB is actually a two-wire serial communication link that runs at
either 1.5 or 12 megabits per second (mbs). USB protocols can configure DEVICES
at startup or when they are plugged in at run time. These DEVICES are broken into
various device classes. Each device class defines the common behavior and
protocols for DEVICES that serve similar functions. Some examples of USB device
classes are shown in the following table
