80C537 Microcontroller remote lab for e-learning teaching

A remote microcontroller lab based on an 80C537 mock-up is presented. This paper presents a new way to interact with these kinds of systems via the Internet, giving the possibility for complete interaction. The Citrix Application Server is the platform which manages the debugging microcontroller software, and National Instruments LabVIEW 8 is used to develop the applications which allow the interaction between the system and the remote user. By means of LabVIEW web server, full remote interaction has been achieved. Our results suggest a new way to practise in laboratories without being present, yet retaining the feel of an actual laboratory environment.Postprint (published version

Simple software simulator for teaching embedded programming

This article presents simple software simulator of a microcontroller evaluation board FRDM-KL25Z. The simulator was developed to make it possible to teach our embedded systems course online during the COVID-19 pandemic. It is in principle a software library that handles function calls and register access from student's program and displays the outputs in a console window of a stan-dard desktop application. It does not require any special hardware or software tools except an IDE capable of building C++ applications for the desktop com-puter. It can be easily modified for different microcontrollers and thus can be useful if existing lessons need to be switched from in-person to distance learning at a short notice

Implementation of Time and Frequency Response Analysis for Web-Based Laboratories

ABSTRACT The University of Dar Es Salaam has developed the web-based laboratory for Time and Frequency Response Analysis. The purpose of this web-based laboratory is the utilization of real data from real experiments, in terms of instrumentation and experimental circuits, rather than simulations. The use of webbased laboratory came after realizing the difficulties imposed by the traditional laboratories. Web-based laboratories allow students and educators to interact with real laboratory equipment located anywhere in the world at anytime. This paper presents the implementation of web-based laboratory of single stage common emitter, resistor capacitor coupled amplifier using National Instruments Educational Laboratory Virtual Instrument Suite platform. Two components are deployed: time response analysis and frequency response analysis. The experiment allows students to carryout time and frequency analysis of the amplifier. The modular can be used to any microelectronic circuits to carry out any time response and frequency response analysis. Both the time response and frequency response analysis results of the amplifier are validated
