Realizer for ST6 and ST7 Differences between ST-Realizer II and Realizer Silver

INTRODUCTION

Realizer is an easy-to-use, Windows®-based environment that allows users with various levels of programming expertise to design embedded applications for ST6 and ST7 microcontrollers using graphical symbols that represent programming functions instead of coding application functions in C or assembler programming language.

Realizer was developed by Actum Solutions and is available in several versions, including:

●ST-Realizer II, a limited version that is only available from STMicroelectronics

●Realizer Bronze, a demonstration version available from Actum (www.actum.com)

●Realizer Silver, the full version available from Actum

This document describes the differences between the ST-Realizer II and Realizer Silver versions. Further, detailed information about ST-Realizer II can be found in the ST-Realizer II User Manual, which is available for free download at www.st.com/mcu.

1 Realizer feature comparison

The following sections list all the features that are available in the Realizer Silver version, which are not available or are limited in ST-Realizer II.

1.1Multi Place

Components can be placed more than once in the schematic after selecting the symbol.

1.2Multi Connect

When connecting the input and output symbols to device pins, you can select the I/O in a combo box. This allows you to connect all I/Os without double clicking on each I/O symbol.

1.3Store String

Text strings entered in a text box will be stored and used when a new label is placed, so that you don’t have to type the string a second time.

1.4Scroll Wire

When you connect symbols to each other, the screen scrolls automatically as the mouse pointer exits the screen (auto-pan).

Application Note

1.5No Borders

In Realizer Silver, this feature allows you to draw schematics that go outside the page borders. In ST-Realizer II, schematics are limited to the page.

1.6Status Box

Realizer Silver provides more information when analyzing projects. ST7-Realizer II reports I/Os, variables by type and required memory space.

1.7Actum Menu

Some functions have been added to the menu to make the Realizer Silver user interface more intuitive, such as:

●F5 — refresh screen,

●CTRL +drag — to move components horizontally or vertically,

●Arrow keys — to move components using the keyboard. Use the CTRL button to increase the steps when moving.

1.8Realizer Help

The Realizer User Guide is provided with the installation of Realizer Silver.

1.9Global Labels

Labels can be applied to the entire design. With ST-Realizer II, labels are only applied to the sheet upon which they were placed.

1.10Controlled

This feature allows you to control the execution of the different sub-schematics. If sub-schematics are not executed, the loop time is reduced.

1.11Symbol Code Support

This allows you to create a symbol and write the assembly code for it. The assembly code is stored in the symbol itself instead of in an include file. In ST-Realizer II, it is necessary to edit the symbol code in the include file.

1.12Active Low Outputs

Outputs can be initialized high at startup. The outputs of ST-Realizer II are set high in the first loop, whereas Realizer Silver allows you to choose to set the outputs low or high at startup.

1.13LCD Control

Realizer Silver allows you to use the LCD peripheral on the ST6240 and ST6280.
