In a nutshell, this book will provide the complete knowledge about the Intel s 8085 microprocessor, its programming and concept of interfacing of memory, IO devices and programmable chips. Each topic has been supported with numerous examples which will help students to apply the concepts to other...
As LCDs are slow speed devices, the tiny speed difference between these modes is not significant. Just remember that microcontroller is operating at high speed in the range of MHz and we are viewing LCD with our eyes. Due to Persistence of Vision of our eyes we will not even feel the ...

The UARTs found in Dallas Semiconductor' 8051-based microcontrollers can easily be configured to interface with the SCI module found in many devices. This popular serial interface can operate in a variety of modes, but the most common are the 10/11-bit asynchronous modes used in RS-232 communi...
Relays are also represented as ideal switching devices in textbooks. Like the switching contacts of an ideal switch, those of a relay are assumed to have zero resistance and a single switching transition that occurs immediately on actuation. As with switches, actual relay contacts, of course, hav...
keyboard interface, the visual display unit, cathode ray tube controller devices, and the drive controllers are discussed, as each of these requires one specific application. this book is useful for computer engineers, software engineers, computer technicians, teachers, and instructors in the field...
The Analog Devices AD667 was introduced in 1984 (Analog Dialogue Vol. 18, No. 2) to provide circuit designers with a low-cost, functionally complete 12-bit DAC. Since that time, the clock speeds of microprocessor-based systems have increased considerably, along with the circuit densities. ...
Matrix keypads are very common input devices in embedded systems. They have simple architecture and are easy to interface. One good thing about them is that they allow you to interface a large number of input keys to a microcontroller with minimum usage of I/O resources. This tutorial describ...
In today’s complex processor devices, the pin functionality and internal connectivity are configured by internal processor registers, as defined in the embedded design phase. In order to create a complete product design, that unique processor configuration needs to be represented in a schematic ...
The invention concerns a method for associating communication devices capable of wireless interfacing. It consists in producing a relationship between communication devices capable of wireless interfa
