LONG
nPixelClockFreq;
Pixel clock frequency (MHz)
TCHAR
tcRegisterChecksum[ MAX_CHECKSUM_LEN ];
Register chcksum (ASCII hex)
} HHP_ENGINE_INFO, *PHHP_ENGINE_INFO;
Sequence structure defines:
#define MAX_SEQ_BARCODES
12
#define MAX_NUM_START_CHARS
32
#define SEQ_ALL_LENGTH
9999
Sequence structure masks:
#define SEQMASK_MODE
0x00001
sequenceMode
#define SEQMASK_BARCODES 0x00002
dwNumBarCodes & seqBarCodes[]
#define SEQMASK_ALL
0x00003
Everything
Individual sequence barcode structure:
typedef struct _tagSeqItem
{
LONG nSymId;
Symbology identifier SYM_xxxx
LONG nLength;
Match length or 9999 to match any length.
TCHAR tcStartChars[ MAX_NUM_STAR1 ]; Matching string (from start)
} SeqBarCode_t, *PSeqBarCode_t;
Sequence structure:
typedef struct _tagHHP_SEQUENCE_MODE
{
DWORD
dwStructSize;
Size of structure in bytes
DWORD
dwMask;
Mask of active items
HHP_SEQ_MODES
sequenceMode;
Disabled/Enabled/Enabled & Required
DWORD
dwNumBarCodes;
This MUST be sent if sending seqBarCodes
SeqBarCode_t
seqBarCodes[ MAX_SEQ_BARCODES ];
Barcodes to sequence in order they are to be
sent
TCHAR
tchSeqCmdBlk[ SIZE_OF_SEQUENCE_BLOCK ];
} HHP_SEQUENCE_MODE, *PHHP_SEQUENCE_MODE;
Decode method stucture masks:
#define DCMASK_MAX_MESSAGE_LENGTH 0x00001
Maximum length of decoded string. This item is Read Only.
#define DCMASK_DECODE_MULTIPLE
0x00002
Look for and report all barcodes in captured frame.
#define DCMASK_USE_AIMERS
0x00004
Use aimers when capturing barcodes.
#define DCMASK_PRINT_WEIGHT
0x00008
Relative contrast between barcode and background (0-9).
#define DCMASK_DECODE_METHOD
0x00010
Normal, linear codes only. Fastest (may miss codes at edges
of image).
#define DCMASK_CENTER_ENABLE
0x00020
Only accept barcodes whose boundaries intersect center win-
dow.
#define DCMASK_CENTER_WINDOW
0x00040
Rectangle about center of image for previous mask.
#define DCMASK_ILLUMINAT_LED_COLOR 0x00080
Illumination LED color to use.
#define DCMASK_ALL
0x000ff
All structure members are active.
Decoder functionality settings:
typedef struct _tagHHP_DECODER_CONFIG
{
DWORD
dwStructSize;
Size of structure in bytes.
DWORD
dwMask;
Mask of active items.
DWORD
dwMaxMsgSize;
Maximum length for any returned barcode string. This is a read
only value.
BOOL
bDecodeMultiple;
Decode and send all symbols decoded with first frame where at
least 1 symbol is found.
