8051 Stopwatch Circuit with Lcd Display

Methods Used in Circuit Design After deciding what to do in circuit design, it is necessary to choose or seek the methods that will save the most time and cost the least. Since our age is home to a time when science and technology may be running horses, there are plenty of alternatives in this field as well.

Maybe beforehand, it would have been very troublesome and costly for us to test the operation of our circuit. But now with “Non-Real Time” methods, this problem is blazing our way in almost most circuit design. “Circuit Design Programs”, which are widely used today, minimize effort and cost. For example; Electronic Workbench, MultiSim, Proteus etc. while computer programs make our life easier in this regard; Boardmaker, Ultiboard, Ares etc. It provides great comfort in printed circuit drawings in programs.

I also designed the project circuit with a simulation program called Proteus. This program provides the person with a virtual laboratory environment. Before the circuit is transferred to the board, it can be tested and checked up to the 8051’s start-up. In addition to providing all kinds of laboratory environments, perhaps one of the most comforting aspects is that correcting errors does not pose a financial problem.

Programs Used in Writing the Program:

There are too many compiler programs used for programming the 8051 IC. All that is left to you is to choose the one that is easiest to use and most advantageous for you. I think that the most advanced compilers for 8051 programming are undoubtedly KEIL UVısion2.

So I used KEIL in the preparation of the project, choosing the most useful and easy one. I can say that the results are excellent. In fact, the same operations could be performed directly with ASSEMBLY commands. Besides the convenience of compilers like KEIL, I can say that the biggest advantage of the compiled/translated program (.HEX) is that it generally occupies less space in memory than those written with ASSEMBLY codes and works more controlled.
