Interfacing A 3x8 Matrix Keyboard with the 8086 Microprocessor
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 2
Abstract
All keyboards are available in a variety of sizes. The standard keyboards are the 101 key QWERTY keyboards interfaced to the microprocessor. The small specialized keyboards are also available which contains only 4, 16 and 24 keys. Such small keyboards can be purchased, preassembled or may be constructed from individual key switches. .The state of the art presented in this paper is the Interfacing of a 3x8 Matrix keyboard with the 8086 Microprocessor. The Assembler used in the system is the MASM assembler. Microprocessor is an integrated circuit, which is the heart of the microprocessor based computer system. In other words a Microprocessor is a finite state automation machine that executes instructions held in a memory. Microprocessor has inputs, outputs and a process. The inputs and outputs of a microprocessor are a series of voltages that can be used to control external devices.
