SERIAL_PORT_CONFIG If using a serial connection imager, this returns the serial port setup
parameters of the imager.
IMAGE_ACQUISITION Returns the current imager settings for capture mode, manual exposure,
manual gain, manual frame rate, target white value, target window, aimer
and illumination duty cycle, and triggering mode (hardware trigger
dependent).
IMAGE_TRANSFER Returns the current image transfer protocols, such as cropping window,
pixel subsample, and transfer compression.
SEQUENCE_CONFIG Returns the sequence mode enable/disable state and the data sequence
command string.
ALL_CONFIG All of the above except serial port config.
pStruct Pointer to the appropriate structure based on parameter “item:”
HHP_BEEPER
HHP_TRIGGER
HHP_DECODER_CONFIG
HHP_POWER_SETTINGS
HHP_VERSION_INFO
HHP_SYM_CONFIG
HHP_SERIAL_PORT_CONFIG
HHP_IMAGE_ACQUISITION
HHP_IMAGE_TRANSFER
HHP_SEQUENCE
HHP_CONFIG
hhpReadConfigStream
Reads the full imager configuration as a single stream of data into a buffer. The buffer contains all the configuration items in an
ASCII stream so that it can be written to a disk for storage. No interpretation is done on the data stream, therefore, the data
stream contains both read only, and read/write data.
Syntax hhpReadConfigStream
(
P BYTE puchCfgStream,
int nMaxLen,
PINT pnBytesReturned
)
Parameter Description
puchCfgStream Buffer to hold the raw imager configuration stream.
nMaxLen Maximum number of bytes that fit in buffer puchCfgStream.
pnBytesReturned Pointer to an integer where the number of bytes returned in puchCfgStream is placed.
hhpReadEngineInfo
Reads information about the image engine contained in the image engine PSOC. This call is only valid for imagers that have a
PSOC. If the attached imager is not an 5X80 image engine, or the engine does not have a PSOC, the function returns the error
code RESULT_ERR_UNSUPPORTED.
Syntax hhpReadEngineInfo
(
P HHP_ENGINE_INFO pEngInfo
)
Parameter Description
pEngInfo Pointer to an engine information structure in which the engine information is returned. The
dwStructSize member must be set to size (HHP_ENGINE_INFO) before making the call.
hhpReadImagerCapabilities
Returns the fixed imager capabilities, such as imager bits per pixel or image capture width and height.
