Widely known as carputer, this system is designed for:
* calculating speed, fuel consumption, economy driving, e.t.c.
* displaying information about temperatures and controll Air Conditioning system in your car.*
* Controlling other devices, like electrically opened windows.*
The system is based on ATMega MCU programmed in C language.
Laser Control is a java program that using a webcam detects when a laser pointer is in a specified hotspot and then does the equivalent of pressing a specified keyboard key. thus Controlling Media Portal through it s hot keys. the hotspots can be set by the user as well as the actions taken. Make your wall into a remote controll.
winavr code for avr mega8. The program get data from serial port in interrupt function. And then out put the data to 74ls595 (serial to parallel IC) for Controlling relay output.
In modern design of digital sysytem,FPGAis widely used,particularly in processing baseband and Controlling whole system.The core of this system is based on FPGA.
Servomotors are available as AC or DC motors. Early servomotors were generally DC motors because the only type of control for large currents was through SCRs for many years. As transistors became capable of Controlling larger currents and switching the large currents at higher frequencies, the AC servomotor became used more often. Early servomotors were specifically designed for servo amplifiers. Today a class of motors is designed for applica-tions that may use a servo amplifier or a variable-frequency controller, which means that a motor may be used in a servo system in one application, and used in a variable-frequency drive in another application. Some companies also call any closed-loop system that does not use a stepper motor a servo system, so it is possible for a simple AC induction motor that is connected to a velocity controller to be called a servomotor.
This book introduces embedded systems to C and C++ programmers. Topics include testing memory devices, writing and erasing Flash memory, verifying nonvolatile memory contents, Controlling on-chip peripherals, device driver design and implementation, optimizing embedded code for size and speed, and making the most of C++ without a performance penalty.
Microprocessors are getting smaller, cheaper and faster. Every day, it is easier to embed more functionality into a smaller space. Embedded processors have become pervasive, and as time goes on, more and more functions that were once implemented with analog circuitry or with electromechanical assemblies are being realized with microcontrollers, ADCs and DACs. Many of these assemblies that are being supplanted by the microprocessor are Controlling dynamic processes, which is a good thing, because the microprocessor coupled with the right software is often the superior device.
