Abstract:

Most times in engineering and other fields, engines need to be transformed from one form to another, in circuits and most components we are familiar with, electrical engines, impulses, digital information, etc need to be changed from one level to another, a motor does this, be it in any kind, pending on the desired function. This literature review examines various research studies that have been done using the PIC 16F84 microcontroller to control stepper motors. The PIC 16F84 is a popular choice for stepper motor control applications due to its simplicity, low cost, and ease of programmability

Abstract:

The limited use of fossil fuels has increased the interest in renewable energy sources. Renewable energy sources are generally direct current (DC) production. The popularity of inverters converting from DC to AC is increasing due to the generation of the generated DC signal and the current grid being alternating current (AC). In this study, a computer-controlled inverter was designed with the 16F877 microcontroller chosen as the model, and frequency and amplitude controls were realized with the serial communication system of this structure. A digital-analog converter (DAC) circuit is formed by

In this paper, a new hybrid test strategy, called hybrid-based self-test (HYBST), is presented to test complex digital circuits such as microcontrollers. This test strategy integrates the signature multi-mode hardware-based self-test (SM-BST) with the software-based self-test (SBST). In this test strategy, the microcontroller is divided into a number of main modules, and then test subroutines are used to functionally test each module, based on its instruction set architecture (ISA). The ISA is used to generate test subroutines that represent test pattern generators (TPGs) and part of the test

This paper considers a digital device for automatic checking of homework assignments in the digital circuits course. The assignment is to make a digital circuit corresponding to a given logical expression; the circuit is comprised of elementary logic gates. The process of manual testing the built circuit is very labor-intensive because checking a circuit with N inputs variables requires checking the correctness of the output variable for 2N cases. We propose automating this pro-cess with a special digital device. The device is comprised of a microcontroller connected to the circuit tested. The

Abstract:

The ultra-fast development of electronics in the last decade, as well as the constant reduction in the price of electronic components, lead to the fact that many manufacturers of household and industrial equipment replace electromechanical components with microcontroller-controlled electronic circuits in the manufactured equipment. The regulator, on the bimetallic plate and the mechanical timer are inferior in many respects to the electronic regulator and the digital timer. In this work, there was a study of an intelligent temperature module, since in industrial automation there is a tendency

Logic boards were failing at Enhanced Mac Minus One (EMMO) test or Integrated Circuit Test (ICT) after printed circuit board (PCB) rework. The failure to boot was originally traced to a suspected bad microcontroller chip. Replacing this chip, or an oscillator tied to the microcontroller circuit, did not consistently solve the boot problem. With further testing, it was found the microcontroller circuit was very sensitive to resistance and was essentially shorted.A resistor in the microcontroller circuit was identified on the flip side of the PCB.

In the readout circuits of the two-dimensional (2-D) resistive sensor arrays, various auxiliary electrical components were used to reduce their crosstalk errors but resulted in increased circuit complexity. Readout circuits with low-complexity structures were necessary for wearable electronic applications. With only several resistors and a microcontroller, readout circuit based on resistance matrix approach (RMA) achieved low complexity but suffered from small resistance range and large measurement error caused by the output ports’ internal resistances of the microcontroller.
