PT Program Generator (PPG) v5.0

Building a Custom Portable Program

At this point, you should understand the general concepts behind creating and
loading a portable program, although many of the details have yet to be
explained. In this section, you'll create a simple portable program from
scratch. It will allow you to collect data with the portable and upload it to your
PC. A menu that appears when you turn on the portable gives you a choice of
the two possible actions.

Creating Frames and Links

A program's frames define its general functions, such as collecting and upload-
ing data. Links connecting frames indicate program flow—how you move
from frame to frame. The details for the program are contained in the pro-
gram’s

Operation

nodes.

Creating Frames

For your program, you will create three frames:

Main

Menu

,

Collect Data

, and

Upload Data

. The program will start with the

Main Menu

frame, which offers

access to the other frames. You can return to the

Main Menu

from either the

Collect Data

or

Upload Data

frames.

Create the frames shown in

Figure 78 on page 107

by completing the following

steps:

1. If you took a break and exited PPG, select

Programs > PT Program

Generator > PT Program Generator

from the Windows

Start

menu to

load PPG.

1. Click on the

Maximize

button, if necessary, to expand the windows to

fill the screen.

2. If you are continuing from the last section, select

File > Close

to close

the

Sample

application. The select

File > New

so that you can create a

new flow chart. (If prompted to do so, do not save changes.)

3. Select

Create > Frame

to draw the first frame. A box labeled

FRAME

appears in the lower right corner of the window. Move it to the top-
middle area of the workspace.

To adjust the position of a frame, just drag it with the mouse. To delete an unwanted
frame or node, select it and then press

DELETE
