Cognitive radios have become a vital solution that allows sharing of the scarce
frequency spectrum available for wireless systems. It has been demonstrated
that it can be used for future wireless systems as well as integrated into 4G/5G
wireless systems. Although there is a great amount of literature in the design of
cognitive radios from a system and networking point of view, there has been very
limited available literature detailing the circuit Implementation of such systems.
Our textbook, Radio Frequency Integrated Circuit Design for Cognitive Radios, is
the first book to fill a disconnect in the literature between Cognitive Radio systems
and a detailed account of the circuit Implementation and architectures required to
Implement such systems. In addition, this book describes several novel concepts
that advance state-of-the-art cognitive radio systems.
The mature CMOS fabrication processes are available
in many IC foundries. It is cost-effective to leverage the
existing CMOS fabrication technologies to Implement
MEMS devices. On the other hand, the MEMS devices
could also add values to the IC industry as the Moore’s law
reaching its limit. The CMOS MEMS could play a key role
to bridge the gap between the CMOS and MEMS
technologies. The CMOS MEMS also offers the advantage
of monolithic integration of ICs and micro mechanical
components.
With all the recent hype over radio frequency identification (RFID) and
the requirements to Implement it, you might think that RFID can turn
water into wine, transform lead into gold, and cure the world’s diseases. You
might also be worried that RFID will enable Big Brother to track your move-
ments to within a foot of your location from a satellite five hundred miles up
in space. The truth is, RFID can do none of these things.
In this chapter, you find out the basics of what RFID is, what forces are dri-
ving RFID as a replacement for the bar code in the marketplace, and what
benefits RFID can offer
If register should be written or read.This value is passed to the calback functions which support either reading or writing register values. Writing means that the application registers should be updated and reading means that the modbus protocol stack needs to know the current register values.See also: eMBRegHoldingCB(), eMBRegCoilsCB(), eMBRegDiscreteCB() and eMBReglnputCB().Enumeration values: MB_REG_READ Read register values and pass to protocol stack.MB_REG_WRITE Update register values.Note: Note all ports Implement this function.A port which wants to get an callback must define the macro MB_PORT_HAS_CLOSE to 1.Returns: If the resources where released it return eMBErrorCode:: MB_ENOERR. If the protocol stack is not in the disabled state it returns eMBErrorCode:: MB_EILLSTATE.Examples: LINUX/demo.c, MCF5235TCP/demo.c, STR71XTCP/demo.c, WIN32/demo. cpp, and WIN32TCP/demo. cpp.his function disables processing of Modbus frames.Returns: If the protocol stack has been disabled
In this presentation, we will look at what the Serial Peripheral Interface, otherwise known as the SPI, is. and how it is used to communicate data to and from the PICmicro microcontroller.SPl is frequently used when few 1/O lines are available, but communication between two or more devices must be fast and easy to Implement.In this presentation, we will discuss the following topics: We will first cover an Overview of SPI This section of the tutorial will introduce you to SPI and its concepts.Next, we will examine the use of SPI on the PICmicro MCU.The details of how SPI is Implemented on a PICmicro device will be examined.Then, a Code Walkthrough will be given.The walkthough will explore code for both an SPI Master and SPI Slave. The example will have the Master generate data for sending to the slave.Finally, there will be a few resources given at the end of the presentation. These resources will allow you to explore in more detail the SPI interface
