Abstract
In electronics, testing tools is a major part when it comes to laboratory work. It’s a part of everyday activity to use one or several too while working on electrical system. No workman can do without testing tools. It is of great importance on practical basis. Thus the aim of this research is to build a Logic tester capable of testing most 74 series logic gates integrated circuits using a Microcontroller (AT89C51). This project is basically designed test or determines the condition of the gates in a logic gate IC by simulating its characteristics using the truth table of the particular IC. Different design approaches were compared and finally one approach was implemented. Each individual module was designed separately. After successful simulation and testing, they were put together to create the finalized version.
Highlights
The Logic gate tester is used to test integrated circuit logic Integrated Circuits (ICs)
The job of the assembler is to convert the source code produced by the programmer into an object code file. It works by replacing each line of assembly instruction code with the corresponding machine code instruction that will be executed on the target microcontroller
The job of the linker is to take the object file produced by the assembler and link it with standard library modules to produce a complete working executable file that can be loaded into the memory of the microcontroller
Summary
The aim of this research is to build a Logic tester capable of testing most 74 series logic gates integrated circuits using a Microcontroller (AT89C51)
