It starts at the beginning and does not assume any previous knowledge of microprocessors or microcontrollers and, in gentle steps, introduces the knowledge necessary to take those vital first steps into the world of the micro. The purpose of this book is to give a worry-free introduction to microprocessors and microcontrollers. They are our constant, unseen companions and billions are being installed every year with little or no publicity. They share our homes, our vehicles and our workplace, and sing to us from our greetings cards. While the microprocessor is at the heart of our computers, with a great deal of publicity, the microcontroller is quietly running the rest of our world. This is certainly still true but it is even truer if we include the microcontroller. The first edition of this book started with the words: ‘A modern society could no longer function without the microprocessor.’ In some cases, the “interface” is not required (if we are not going to create class instances), but the other two are must.Genre: comp_hard Introduction to Microprocessors and Microcontrollers John Crisp – “Implementation” file that implements the clauses, etc. – “Class” file, that declares the class-specific interface – “Interface” file, which defines the interface/behaviour provided by the “objects” of a class

Since Visual Prolog is “object oriented”, functionality is implemented in classes, whose code is distributed in three files: In case the integer “key” is not present, it will assign “-999999” to the output argument.Īs you can see, Visual Prolog supports functions and procedures too, in addition to the regular non-deterministic “Horn Clauses” . The DLL provides the following:ġ) A function called “factorial” that takes an integer argument and returns the corresponding factorial of the argument.Ģ) A procedure called “lookup” that takes two arguments: an integer, which acts as a “key” for lookup and and an “out” parameter that corresponds to the looked up value. Getting back to our main topic, I decided to create a DLL in Visual Prolog. In that sense, since Prolog is a declarative language and is good at logical inferencing, we might consider using it to implement an application such as a Medical Diagnosis system that has an Expert System subcomponent.

The capability to use DLLs (in Windows environment) written in one language can come in handy if we want to exploit the language’s special features for implementing specific functionalities, even though the main application is written in another language say, Erlang, Go, etc. I do this usually with other languages too, see for example this and this. Instead of writing the canonical “Hello, world! “ program, I wanted to start by implementing a DLL that I can call from C/C++. I upgraded to the latest version (ver 10) a couple of weeks ago and decided to spend some time understanding the language and the environment.

There are a couple of PDF books but they cover an older version (ver 7.x or earlier). One reason is that it seems to have a steeper learning curve and there are not many video tutorials to explain the language and the environment. So, if you don’t need a “Standard” Prolog, then Visual Prolog has a lot to offer.Īlthough I purchased the Commercial Edition of Visual Prolog a few years ago, I never got around to using it. Because of strong typing and compile-only strategy, the efficiency of generated code is likely to be superior compared to other interpreted environments. We can quickly build Console mode or GUI-based applications, DLLs, and even Windows Service using the platform. Visual Prolog is quite rich in functionality. So how is Visual Prolog different from other Prolog implementations out there, for example, SWI-Prolog or Sicstus Prolog?Ģ) It is strongly-typed and is object-orientedģ) It is a compiled environment, not interpreted It is developed and supported by PDC A/S, Denmark. Visual Prolog has its roots in Turbo Prolog, which was popularized by Borland in the mid 1980s.
