Point Grey Flea3 GigE Technical Reference E Control and Status Registers
E Control and Status Registers
Some features of the Flea3 GigE are accessible only using control and status registers (CSRs) that conform to the IICD
1.32 standard.
These include the following:
n
Frame Buffer— IMAGE_RETRANSMIT: 634h
n
Flash Data memory— DATA_FLASH_CTRL: 1240h
n
Pulse Width Modulation— GPIO_CTRL_PIN: 1110h-1140h and GPIO_XTRA_PIN: 1114h-1144h
n
Trigger Modes— TRIGGER_MODE: 830h
n
Pixel Clock Frequency— PIXEL_CLOCK_FREQ: 1AF0h
n
Lookup Table— LUT: 80000h – 80048h
n
Embedded Image Information— FRAME_INFO: 12F8h
n
Initialize— INITIALIZE: 000h
n
Time from Initialize— TIME_FROM_INITIALIZE: 12E0h
n
Link Up Time— LINK_UP_TIME: 12E4h
n
Transmit Failure— XMIT_FAILURE: 12FCh
n
Video Mode Error— VMODE_ERROR_STATUS: 628h
n
Camera Log— CAMERA_LOG: 1D00 – 1DFFh
n
Pixel Defect Correction— PIXEL_DEFECT_CTRL: 1A60h
A complete list of CSRs can be found in the Point Grey Digital Camera Register Reference available from the
Downloads page.
E.1 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.
For GenICam features, One shot is the same as Single Frame and Multi shot is the
same as Multi Frame.
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.
