Delphi Xe5 Serial Port 5,0/5 8936 reviews

Delphi classes that wrap the MS UIAutomation library. DelphiUIAutomation is a framework for automating rich client applications based on Win32 (and specifically tested with Delphi XE5). It is written in Delphi XE5 and it requires no use of scripting languages. The serial port but have to somehow hook into the entry and exit points of the data with the socket system. And Async Pro does not cut it since I cannot install it in my XE5. The application was migrated to XE5 a year ago. Meanwhile I have built a small TCP-to-Serial utility with Delphi 2007.

Serial Port Arduino
Delphi Xe5 Serial Port Component
Delphi Xe5 Com Port

I too found myself in the position of going on using CBuilder 6 and the free Turbopower serial port component for much longer than I expected. I had a couple of warnings about this cosy state of affairs. The first being that after getting XE I could not load the Turbopower component.

I have successfully used Winsoft ComPort for Android to perform a serial USB communication.

Check out the code.

At the component Properties, you must include essential characteristics that creates your Serial port communication.

GLScene allows you to quickly design and render 3D scenes without having to learn the intricacies of OpenGL, if you know how to design a TForm, you'll easily master the basic operations of GLScene. The library comes with a large collections of demos showcasing the ease of use, and demonstrating RAD wasn't done at the expense of CPU/GPU horsepower.
SynGdiPlus. Enables an application to load and save GIF, TIF, PNG and JPG pictures. It also allows anti-aliased drawing from any TMetaFile. That is, you can play a .emf content using GDI+ instead of GDI, for much better rendering result.

Based on AggPas, which is itself based on the Anti-Grain Geometry, this project offers support for the latest Delphi Versions (XE and above) and contains some helper classes (VCL components and FireMonkey interface). 2D vector graphics library. Basically, you can think of AggPas as of a rendering engine that produces pixel images in memory from some vectorial data. But of course, AGG can do much more than that.// Vector graphic library, renders SVG and much more
delphi-shader. Hundreds of graphical effects, and a library that provides GLSL functionality in pure Delphi code.

The original work was done by Martin Waldenburg in the late 1990s, and the project was abandoned sometime before 2003, when I found the code and began working on it. I have kept it updated as necessary to work with my project, called 'Castalia'.

It provides all the basic arithmetic operations on Integers, comparing, bitwise shifting etc. It also allows parsing numbers in different bases and converting them to string, also in any base. The advantage of this library is its fast multiplication, division and from base/to base conversion algorithms. all the fast versions of the algorithms are based on fast multiplication of big Integers using Fast Hartley Transform which runs for O(N * log N * log log N) time instead of classic O(N^2).
