چکیده
In this paper a Microcontroller based intelligent digital volume controller is presented to control music system and PC speaker volume digitally and change volume levels automatically in case of certain predefined incidents such as incoming or outgoing telephone call and pre-set alarm. The device is constructed with AT89S52 microcontroller, from ATMEL family with 8051 architecture, and its software program being written in C language.

Abstract This paper describes a mixed-signal integrated circuit implemented in low-cost CMOS technology optimized for dc/dc and ac/dc converter applications. The device is partitioned into a hardware digital controller comprised of a digital signal processor (DSP) controller and an instructionbased microcontroller (MCU) system management processor section. The hardware digital controller includ...
متن کاملMicro-Controllers: An Overview
With the advent of low-cost processors and accessories, the ability to do control digitally has become increasingly feasible; this has led to a dramatic change in the way controllers are designed, tested, and implemented. Moreover, these digital controllers are usually more robust and easier to design than their analog counterparts. A micro-controller (MC) is the processor that is used to do th...
متن کاملDesign of Intelligent Traffic Control System Based on ARM
Nowadays congestion in traffic is a serious issue. The traffic congestion can also be caused by long Red light delays, etc. The delay of respective light is hard coded in the traffic light and it is not dependent on traffic. Therefore for simulating and optimising traffic control to better accommodate this increasing demand is arises. In this project we discussed the optimisation of traffic lig...

In the paper, two approaches to measurements of circuit functions of analog parts of mixed-signal systems controlled by microcontrollers are presented. They base on the utilization of internal resources of the microcontrollers. The first approach uses an analog to digital converter (ADC), an analog comparator and a timer. The second one uses only the ADC and the timer. The measurement procedure...
