The concept of the fuzzy logic makes feasible the creation of fuzzy controllers with low cost 16 bit microcontroller having the same performance as of controllers realized with more expensive Digital Signal Processor (DSP). In this article the implementation of such a fuzzy controller is proposed for 16 bit microcontroller with fast fuzzyficationinference-defuzzyfication algorithm. Because the ...

Received Nov 1, 2011 Revised Jan 18, 2012 Accepted Jan 28, 2012 In this paper, we have proposed a technique by which customized sound can be generated using 8 bit AVR microcontroller. Any sound file chosen from computer can be integrated in microcontroller programming which is written in C and compiled by AVR libc compiler. An 8 bit DAC connected to PORT A of AVR microcontroller takes data of s...

Embedded systems are often used in security-critical scenarios where physical access of an adversary cannot be prevented. An attacker with unrestricted physical access to an embedded device could thus use observation-based attacks like power analysis or chip probing techniques to extract chip-internal secrets. In this work, we investigate how to counteract first-order passive physical attacks o...

Avoider robot is mean robot who is designed to avoid the block in around. Except that, this robot is also added by an addition aplication to dim the fire. This robot is made with ultrasonic sensor PING. This sensor is set on the front, right and left from robot. This sensor is used robot to look for the right street, so that robot can walk on. After the robot can look for the right street, next...

Microcontroller-based systems require the design of a hardware/software interface that enables software running on the microcontroller to control external devices. This interface consists of the sequential logic that physically connects the devices to the microcontroller and the software drivers that allow code to access the device functions. This paper presents a method for automatically synth...

Automatic control of DC servo motor in terms of rotation angle has played a vital role in the advance Electromechanical Engineering. Nowadays, the automatic process of motor control using a Personal Computer (PC) is commonly used. The controllers are designed to interface between a Computer and Motor. This paper presents the implementation of PIC Microcontroller with Graphical User Interface (G...

A PIC17C44 microcontroller development board and a real-time algorithm were developed with the capability of monitoring the fetal heart rate (FHR) as well as recording both the FHR and maternal heart rate for long-term. This paper describes the development of the microcontroller board and implementation of a real-time algorithm which were used to develop the portable recorder. Two set-up were d...

Testing method of ADC’s implemented on microcontroller chips are descibed in the paper. The achieved results for microcontroller AT90S8535 and ADuC812 are discussed too. As a criterion of ADC precision, which allows to determine the operational condition limits, the number of effective bits has been chosen. More over, the DNL and INL measured characteristics are presented. The results are compa...

This paper presents a non-intrusive framework for runtime verification of executable microcontroller code. A dedicated hardware unit is attached to a microcontroller, which executes the program under scrutiny, to track atomic propositions stated as assertions over program variables. The truth verdicts over the assertions are the inputs to a custom-designed μCPU unit that evaluates past-time LTL...

In the frame of an ESA activity, ADV Engineering is developing a microcontroller based on the well-known Intel 8052 device. The objective is to develop a microcontroller for applications with moderate processing requirements but needing high safety and easy accommodation of equipment interfaces. This component is therefore a good candidate for embedding in a large variety of platform and payloa...
