Chapter 21. Format Editor
Using the FormatEditor you can define format sets. A format set is stored in a file with .dff extension.
Each format set consists of one or more format definitions which the Analyzer application can use to
display formatted data in a table form or layout form.
For instance for the SBP2 protocol support of the Analyzer, a number of format sets have been defined.
One format set for each supported SBP2 device type.
In a format set for the SBP2 protocol you will find format definitions that define the format for the
'command' or 'data' blocks. See 'FormatEditor and the SBP2 protocol' document for more details on this.
A format definition defines how the data block is build up with fields. A field is associated with one or more
bits of the data block. It has a field name, a field type and some other properties.
The format definition defines sequentially all the fields of data. It can use a 'repeat' construction (like a
while in C-language), it can use the 'if' and 'else' construction (similar to the C-language), it can use the
'switch' and 'case' construction (similar to the C-language) and it can use 'macro' calls (similar to function
calls in the C-language).
A format definition can be defined using a simple to use interface, where you can add the 'field', 'repeat',
'if', 'switch' (etc) items in a tree and edit their properties.
After creating a definition, you can check the result. The result will be displayed in a table view and a
layout view. You can change field values to check conditional behaviour of the format definition.
21.1. How to use it
The Format Editor can be found in the same 'Start' menu as the Analyzer application. After starting it, the
following window will show up:
In the left pane of the window (Definition pane), you can create the definitions tree. The properties of a
selected item is shown below the tree and can be changed there.
In the right pane of the window (Result pane), you can check the resulting format of a selected definition.
When the 'Update Result' button is clicked, the resulting format will be shown as a table and a layout view.
You can change field values to verify correct behaviour.
