• There are 3 product lines in the PEG Suite

− PEG Pro

− PEG+

− C/PEG

• Each product line has two components

− WindowBuilder – this is the tool to build the UI and auto-generate the source application source files

− PEG Runtime Library – this is the code that executes the UI once its written

9 TM

These can change

So can this

• PEG’s modular form extends an application across architectures and RTOS.

− The core library is separated from the interfaces to different RTOS’s, input devices, and screen controllers.

− Changing the drivers DOES NOT mean changing the application.

• The eGUI structure

is divided into two

groups:

• High level –

platform

independent layers

• Low level – HW

interaction layers

eGUI High Level

eGUI Low Level

(HW interaction)

33 TM





• User application layer –

user code base

• D4D driver layer – main

code base of eGUI

− Graphic object code

base (D4D_BUTTON,

D4D_LABEL etc.)

• Interaction layer with

low level drivers

34 TM





• Divided into two layers

• LCD / Touch screen

Controller Layer –

handles the needs of

different LCD controllers

and touch screen read

methods

• Hardware interaction

layer – service the

interaction of

LCD/Touch screen

controller driver with

HW.

35 TM

• The basic item of D4D structure is SCREEN

• The screen represented the real one screen showed on LCD

• The screen contains:

− list of all used objects on screen

− functions bodies:

OnInit – One time called function with first use of screen

OnActivate – Function called with each activation of screen

OnDeactivate – Function called before deactivation of screen

OnMain – Function is called periodically when screen is active

OnObjectMsg - Function is called with all system messages of this screen

• The screen functions are designed to simplify the application

code

Features:

• Activate screen

• Escape screen

• Replacing screen in
