After configuring USB-FS memory I now have the camera running.

One thing I don't understand is that I can't set the Acquire period below 0.375 seconds, i.e a frame rate of 2.66 Hz.

Is there a bandwidth limit somewhere?

Thanks,

John

I have built, base-7.0.6, areaDetectorR3-13 with ADSpinnaker master on Alma 9. I am using a FLIR BlackflyS 161S7M USB camera. This is large, 5320x3032 pixels.

The camera is detected but I get a "Not enough available memory to allocate buffers for streaming" error.

In ADSpinnakerConfig I have set numSPBuffer to minimum = 10 (?)

# ADSpinnakerConfig(const char *portName, const char *cameraId, int numSPBuffers,

# size_t maxMemory, int priority, int stackSize)

ADSpinnakerConfig("SP1", 22671882, 10, 0, 0,0)

The host computer has 16G, 13.7 G free,

Ideas?
