By doing this lab tasks, we had learned about how to use the MSDOS editor and the MDA-8086 Experiment Board. The MSDOS editor was important in this task where we need to view, create, or modify of these files which are MATRIX.ASM, MATRIX_1.ASM, MATRIX_2.ASM, MATRIX_3.ASM and MATRIX_4.ASM for error. This editor makes those programs easy on being assemble for any error following the instructions given. A dot matrix is a 2-dimensional patterned array, used to represent characters, symbols and images. Every type of modern technology uses dot matrices for display of information, including cell phones, televisions, and printers. They are also used in textiles with sewing, knitting, and weaving. The KMD D1288C is 1.26 inch height 3mm diameter and 8 × 8 dot matrix LED displays. The KMD D1288C is dual emitting color type of red, green chips are contained in a dot with milky and white lens color. The display consists of a dot matrix of lights or mechanical indicators arranged in a rectangular configuration (other shapes are also possible, although not common) such that by switching on or off selected lights, text or graphics can be displayed. A dot matrix controller converts instructions from a processor into signals which turns on or off lights in the matrix so that the required display is produced.
From this third lab assignment, we learned on how to assemble the error based on the codes given and we also learned on how to make the all the dot matrix light up and off following the instruction given.
INTRODUCTION
A dot-matrix display is a display device used to display information on machines, clocks, railway departure indicators and many other devices requiring a simple display device of limited resolution.
LED dot matrices are very popular means of displaying information as it allows both static and animated text and images. Perhaps, it was encountered at gas stations displaying the gas prices, or in the public places and
