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.
