The increasing interests in using renewable energies are coming from solar thermal energy and solar photovoltaic systems to the micro production of electricity. Usually we already have considered the solar tracking topology in large scale applications like power plants and satellite but most of small scale applications don’t have any solar tracker system, mainly because of its high cost and com...

Cooperation of the analog and digital circuits and the embedded controllers as well as their industrial use and technical application has always been in the focus of my interes. In reconfigurable systems the effectiveness and quality of the analog circuit system can be maintained and modified by circuit or by changing the single element values. There are further advantages of the programmable a...

A method for model checking of microcontroller code is presented. The main objective is to check embedded C code including typical hardware specific ingredients like embedded assembly statements, direct memory accesses, direct register accesses, interrupts, and timers, without any further manual preprocessing. For this purpose, the state space is generated directly from the assembly code that i...

This paper presents a tested research concept that implements a complex evolutionary algorithm, genetic algorithm (GA), in a multi-microcontroller environment. Parallel Distributed Genetic Algorithm (PDGA) is employed in adaptive beam forming technique to reduce power usage of adaptive antenna at WCDMA base station. Adaptive antenna has dynamic beam that requires more advanced beam forming algo...

In recent years, microcontrollers have been used in many areas. Implementation of a circuit by using several discrete analog and digital devices can be done using only one microcontroller. However, industrial microcontrollers have limited resources to implement complex mathematical functions, such as Taylor series. In this work, implementation of Taylor series on a PIC microcontroller is given....

Given energy as the limiting factor in a low-power battery-driven embedded microcontroller (MCU), energy-efficient operation is critical. Low-energy microcontrollers benefit from comparable performance and longer lifetimes when compared to microcontroller cores without energy saving schemes. Dynamic voltage and frequency scaling (DVFS) has been proposed in [1] as a novel technique to provide op...

This paper describes the development of a heart rate monitor system based on a microcontroller. It offers the advantage of portability over tape-based recording systems. The paper explains how a single-chip microcontroller can be used to analyse heart beat rate signals in real-time. In addition, it allows doctors to get the heart beat rate file of the patient by email every twenty four hours. I...

A new solution of a smart microcontroller sensor based on a simple direct sensor-microcontroller interface for technical objects modeled by two-terminal networks and by the Beaunier’s model of anticorrosion coating is proposed. The tested object is stimulated by a square pulse and its time voltage response is sampled four times by the internal ADC of microcontroller. A neural classifier based o...
