WAVECOM Data Formats

The Classifier data is stored in the way described in chapter

File Header

on page 303.

The data package which contains the text “CodeCheck Data Section” marks the beginning of the Co-
deCheck data section.

The CodeCheck data of a classified signal is written to a single string. The following values are written to
the string:

The index value of the classified signal.

The string value with all predicted modes.

All detected modes( can be more than one), for a detected mode the following values are written

to the string:

-

Mode: the name of the detected mode, e.g. ‘FEC-A', 'ASCII'.

-

SubMode: the name of the submode e.g. 'SREG - 72 Bits' by FEC-A, '9 Bits' by ASCII-mode

-

additional description, information: e.g. 'Shift Reg: 72 Bits'

-

the hits value. Shows how often during checking, a mode was successfully determined

NOTE: the values are written to the string in the same order as listed above!

If not stored with _UNICODE enabled, then the string contains normal 8-bit characters values, from type
char, otherwise the string contains 16-bit characters, from type wchar_t.

A char value occupies 1 Byte and a wchar_t value occupies 2 Bytes in the binary .WDA file.

Graphics data

The FileType stored in the file header is “Graphics”.

Header data

This file type uses the ‘File Header’ described in chapter

File Header

on page 303.

The Phase value, the AspectRatio (could be stored in old WAVECOM Data Files, for the actual Software it is
not stored anymore) and the Flip Left/Right/Top/Bottom value are stored additionally to the default head-
er.

The following additional data is stored in the Header, following the default header:

Phase: Value for moving the image horizontal

Pad: padding bits for alignment ( not used )

AspectRatio: obsolete, no longer used in the actual software

FlipHV: 0 = FlipLeftRight & FlipTopBottom disabled, 1 = FlipLeftRight, 2 = FlipTopBottom, 3 =

FlipLeftRight & FlipTopBottom

Pad: padding bytes for alignment (not used)

To the default file header with 64 bytes additional a block of 24 bytes is added that contains the Phase,
the AspectRatio, the FlipHV and some padding bytes for alignment.

The Phase value occupies 4 Bytes followed by 4 padding bytes. The Aspect Ration occupies 8 bytes. The
FlipHV (Flip horizontal vertical ) value occupies 4 bytes followed by 4 padding bytes.

NOTE: the following struct type could be used to extract the data header.
