Abstract
In this project, we will have brief discussion on how to interface 16×2 LCD module to AT89C51, which is an 8051 family
microcontroller. We use LCD display for the displaying messages in a more interactive way to operate the system or displaying
error messages etc. Interfacing 16×2 LCD with 8051 microcontroller is very easy if you understanding the working of LCD Hence,
in this project, I will not only give the information of LCD and also provide the code in using machine language which is working
fine without any errors.
Keywords: Control Systems
Description
Our vision of model-based development rests on two pillars: Explicit product models, which for the developer appear as domainspecific
languages, and explicit process models, which define the developer’s activities that transform early, abstract, partial
products to the final, concrete and complete products that are ready to be delivered and deployed.
The benefits of model-based development come from the interaction of process and product models and their realization in a
CASE tool: Firstly, complex design steps such as refractoriness or the introduction of complex communication patterns [11]
between components can be naturally defined and performed in a tool. Secondly, the application of such design steps naturally
leads to a development history that can be recorded in the tool and used for a kind of high-level configuration and version
management. Finally, the requirements and design rationales that influence design steps can be traced and documented throughout
the complete development process.
However, model-based development is not without risk. It is not obviously clear whether a seamless development process from
early design to final target code is feasible: Some design steps might demand knowledge of environment properties which are
difficult to formalize. Design steps in the later phases will require precise knowledge of the target platform, for instance to access
device drivers or in order to estimate the worst case execution times which are needed as input for scheduling algorithms.
