Issues with Fresco FL1100 controller

xiGetImage Timeout when small ROI is Active

Conditions:

  • usage of driver 3.5.* or 3.8.*,
  • operating system - Windows 7, Windows 10,
  • payload size is smaller than ~200 KB (e.g. ROI 600x350, or smaller, with output bit depth of 8bit).

Observation:

  • in application - xiGetImage returns timeout,
  • in CamTool - after setting small ROI:
    • camera framerate drop to 0,
    • camera disconnect a reconnect itself.

Solution:

  • in application - set number of buffers to commit to value 500 with command:
    xiSetParamInt(xiH, XI_PRM_ACQ_TRANSPORT_BUFFER_COMMIT, 500);
    
  • in CamTool - after re-connection of camera set larger ROI.
