E Control And Status Registers; Image_Retransmit: 634H - FLIR GRASSHOPPER 3 Series Technical Reference

E Control and Status Registers
Some features of the Grasshopper3 PGE are accessible only using control and status registers (CSRs) that
conform to the IICD 1.32 standard.
These include the following:
Frame Buffer—IMAGE_RETRANSMIT: 634h

Trigger Modes—TRIGGER_MODE: 830h

IMAGE_RETRANSMIT: 634h

This register provides an interface to the camera's frame buffer functionality.
Transmitting buffered data is available when continuous shot is disabled. Either One shot or Multi shot can be
used to transmit buffered data when Transfer_Data_Select = 1. Multi shot is used for transmitting one or more (as
specified by Count_Number) buffered images. One shot is used for retransmission of the last image from the
retransmit buffer.
Image data is stored in a circular image buffer when Image_Buffer_Ctrl = 1. If the circular buffer overflows, the
oldest image in the buffer is overwritten.
Transmitted data is always stored in the retransmit buffer. If a last or previous image does not exist, (for example,
an image has not been acquired since a video format or mode change), the camera still transmits an image from
the retransmit buffer, but its contents are undefined.
The image buffer is initialized when Image_Buffer_Ctr is written to '1'. Changing the video format, video mode,
image_size, or color_coding causes the image buffer to be initialized and Max_Num_Images to be updated.
