Design and Development of an Asynchronous Serial Communication Learning Media to Visualize the Bit Data

Abstract

There were some limitations in the old version of serial communication learning media. The old module only showed some of data bits instead of full format data bits. There was no a signal graph display on that module as well. By utilizing the graphics LCD on our proposed module, the serial data information could be presented completely. This paper presents the design and development of an asynchronous serial communication module which can be used as a learning media in Data Communication course. To evaluate the serial module, four scenarios of the functional-based test has been performed, i.e. 1) performing basic functions test, 2) receiving data test, 3) sending data test, and 4) visualizing data test. The results showed that the serial communication module could performed all its intended functions correctly.
