This book is for developers who design and program devices that use the
Universal Serial Bus (USB) interface. My goal is to introduce you to USB
and to help you get your devices up and communicating as quickly and easily
The USB interface is versatile enough for a wide range of peripheral devices.
Standard peripherals that use USB include mice, keyboards, drives, printers,
and audio/video devices. USB is also suitable for data-acquisition units, control
systems, and other devices with specialized functions, including
The developers chose the 8088 over the 8086 because, while the 8088 worked on a 16-bit basis internally, it only
communicated with the outside world using an 8-bit data bus. Since the 8-bit DataMaster data bus already existed, the 8088
was the obvious choice. This bus connects the motherboard of the PC, where the processor and its support chips are resident,
to the memory and the expansion boards, which are plugged into the expansion slots.
In a time when digital electronics is becoming more complex and less accessible to
students and low-end project and product developers, microcontrollers have become
the tools of choice for learning about electronics and programming as well as providing
the capabilities needed to create sophisticated applications cheaply and easily. If
you were to look through any electronics magazine, you would discover that almost
every example application uses a microcontroller (often abbreviated to just MCU) to
provide a user interface, sequence operations, and respond to changing inputs.
With the 4GB Gridfire , you can back up, store, carry and offload large files with one affordable, convenient device. What’s more, means no moving parts, and therefore less chance of damage if the device is dropped. 2 The 2GB One-Tech is the best choice for high-performance results from your digital camera and other handheld devices. 3 The STM gives you the ability to carry your files AND your software on a secure USB drive, by using separate partitions to … 4 The Airlink connects your desktop PC to a network, using the latest advanced silicon chip technology....
The behaviors and related benefits (see Benefits) that the target audience is accustomed to —
or may prefer over — the behavior you are promoting. For example, using the elevator competes
with taking the stairs because of ease and quickness; having potato chips with lunch
competes with including a fruit and vegetable at each meal because of taste and low cost;
formula feeding competes with breastfeeding because of convenience and participation by
other family members. Competition also encompasses the organizations and people who
offer or promote alternatives to the desired behavior.
