Tilcon Interface Development Suite (IDS) 白皮书深入探讨了如何通过这个强大的多平台用户界面开发解决方案，简化实时、嵌入式和关键任务应用中的图形用户界面（GUI）和人机交互界面（HMIs）的创建过程。该白皮书首先概述了Tilcon IDS的核心功能和软件架构，强调了它在支持的编译器、处理器和操作系统方面的灵活性。 Tilcon IDS主要包括四个关键组件：Tilcon嵌入式矢量引擎（EVE），这是实现图形处理的基础；Tilcon界面构建器，作为主要的屏幕设计工具，使得用户能够直观地设计和定制界面；Tilcon API，它是应用程序与EVE之间的通信桥梁，确保了数据的无缝交换；以及Tilcon Utility工具，用于管理和维护Tilcon应用程序。 Tilcon的优势在于其高效的工作流程，它让开发者从繁琐的编码工作中解脱出来，专注于创意和用户体验。由于其高度互动性和实时性能，Tilcon特别适合于对响应速度和稳定性有高要求的应用，例如塑料注射成型机、半导体制造设备、信件分拣设备、金属加工和测试设备等领域的产品开发。此外，它还被广泛应用于交通运输行业的仪表系统，如飞机、装甲车、火车机车和潜艇，体现了其在复杂系统中的可靠性和适应性。从技术角度而言，Tilcon的架构设计注重可移植性和可配置性，使得同一个应用程序可以在不同的平台上运行且能够根据需求进行调整。这不仅节省了开发时间和成本，也增强了系统的灵活性和扩展性。用户可以从宏观层面了解整个开发流程，从设计、构建到实际部署，Tilcon都提供了全面的支持。 Tilcon Interface Development Suite白皮书为读者揭示了一个高效、灵活且易于使用的图形界面开发环境，对于任何寻求简化人机交互界面开发的专业人士或企业来说，都是一个值得深入研究和利用的工具。通过理解和利用Tilcon，开发者可以显著提升产品开发效率，缩短产品上市周期，从而在激烈的市场竞争中保持优势。

The second component is a comprehensive set of platform independent API calls. These

provide the communication between your application and the EVE. They support the

dynamic creation of objects and offer total control over object attributes, while remaining

simple and easy to use.

The Tilcon Interface Builder allows you to build complex screens using simple drag and

drop from a broad selection of powerful objects. The appearance and functionality of

these objects can be fully customized using the Builder's straightforward property sheets.

Portability

The Tilcon process is separate from your application and handles all interfaces to the

windowing system. Tilcon's API library is the same on all platforms (windowing systems).

A clean separation between application code and the windowing system is maintained.

It is important to understand that the Interface Builder does not generate any code. When

you use our Interface Builder to build a screen and save it to our twd file format. What is

being saved is more in the nature of a resource file - a collection of labels, coordinates

and instructions that the EVE knows how to interpret and render.

Inside the EVE are generic button routine, a listbox routine, a chart routine. From the

data in the .twd file, the EVE knows where to put the window, how big to make it, how

many buttons there are, where they are, what their labels are, etc. As these .twd files are

data files rather than C code, you can change these files with the Interface Builder with

out having to recompile a thing. This approach shields the developer from volumes of

generated code, minimizes time-consuming recompilations and makes the application

very portable. The files are independent of operating or windowing system and usable on

all supported platforms.

The Tilcon EVE has its own drawing capabilities. All of the objects are Tilcon objects and

not borrowed from the various windowing systems. As a result the screens are identical

from platform to platform. Minor exceptions arise out of limitations of individual operating

systems. Objects can be created using the Interface Builder and saved as part of a twd

file or they can be saved as Tilcon object files in the Tilcon library. Objects can also be

created dynamically and in fact entire screens can be created, edited and saved dynam

ically. Regardless of how they are created, the look and feel will be the same on all the

supported platforms. The only part of the system that is platform specific is the actual Til

con EVE supplied for individual platforms by Tilcon.

The portability of the user interface has many implications and how important these are

varies from application to application. As you can make changes to the user interface

without recompiling, maintenance and upgrading is simplified and for some applications

remote maintenance becomes a possibility.

All screens are entirely reusable. Your prototype becomes your application. You only

need to write your application once and it is immediately available under all platforms

that Tilcon supports. If you are developing a product and want to maximize your market

by releasing on multiple platforms, Tilcon’s capabilities are ideal. Many device manufac

turers like the fact that although their actual machine or device may be using an RTOS,

their sales force are able to walk around with the same application in their Windows lap-

top. Same considerations apply to training systems.

Another major advantage is cross-platform development. The choice of tools in some

platforms may be more limited. It may be difficult to get specialized developers. The need

to constantly download to a target may be inconvenient. The ability to do the bulk of the

development on a standard operating system with your favorite development environ

ment and better tools with only fine-tuning on the target is a real advantage.

The Tilcon design tools (Interface Builder) is very user friendly and designers, artists and

developers can easily work in concert even in a mixed environment. With built-in TCP/IP

networking, you can display and control in a heterogeneous environment. Your data

acquisition or device can be on an RTOS and it can easily integrate into your desktop

environment. Having the ability to easily move to another operating system may provide

leverage and freedom of choice in the future.

Tilcon Embedded Vector Engine

Tilcon's EVE is in effect a very sophisticated graphics driver. In addition to executing all

API commands and rendering the screens, it is responsible for maintaining the main data

structure that describes all of the object spaces and objects and processes window mes

sages, triggers, notifications and callback functions.

It is the go-between for your application and the windowing system. It knows how to read

a .twd file (the screens you create with the Tilcon Interface Builder), how to create a win-

dow from it and how to create all the buttons, text, charts, meters and other objects within

the window. It knows what windowing system commands to use to update an object, how

to get the value stored in an object and how to detect when the user changes an object.

It runs side-by-side with your application and in response to its API commands loads and

displays the required windows, puts values into the meters, charts and other objects. The

Engine tells the application about text modifications, button clicks and other user interac

tions with objects in your interface window.

Triggers are in effect API commands that were built into the objects themselves when

they were created. In response to specific events, for example, a checkbox becoming

un-checked, the Engine executes the trigger that was built into the selected object. In this

way, a button could be used to dim several fields and display a window, without the need

to communicate with your application.

The Server is the part of the EVE that handles the graphics services for the user applica-

tion. It replays and translates API calls to instructions understood by the Engine. It also

receives, translates and replays UI events and data to the application.

Application Programming Interface

The API (Application Program Interface) is the protocol between the application and the

EVE. The heart of the Tilcon API is a handful of fundamental functions. These are the

functions that initiate and terminate communication with the Engine, query for notifica

tions, create and delete objects and set or query object attributes. They are as follows:
