RE: Implementing NDTransform plugin for areaDetector

["Pearson, Matthew via Tech-talk" <tech-talk at aps.anl.gov>]

Hi,

dbpf MOBICDTE:Trans1:NDArrayPort "SIM1"
dbpf MOBICDTE:HDF1:NDArrayPort "TRANS1"
dbpf MOBICDTE:image:NDArrayPort "TRANS1”

 

Yes, that would be valid.

2022/06/22 19:47:09.533 asynPortDriver:getAddress: TRANS1 invalid address=2, must be in range 0 to 0

2022/06/22 19:47:10.635 asynPortDriver:getAddress: TRANS1 invalid address=2, must be in range 0 to 0

And the messages kept going untill i finally gave up and stopped acquisition. I suspect this has something to do with MOBICDTE:image:NDArrayAddress = 2 and MOBICDTE:Trans1:NDArrayAddress = 0. But i cannot understand exactly what is going on or what is the problem with Trans1:NDArrayAddress being equal to 2.

I’m not too sure. As I understand it, mobipixConfig is producing 3 NDArray objects on different addresses on the same port, like this:

SIM1, ADDR=0

SIM1, ADDR=1

SIM1, ADDR=2

?

So you might want 3 transform plugins with a configuration something like:

NDTransformConfigure(“TRANS0”, 200, 0, “SIM1”, 0, 0, 0, 0, 0)

NDTransformConfigure(“TRANS1”, 200, 0, “SIM1”, 1, 0, 0, 0, 0)

NDTransformConfigure(“TRANS2”, 200, 0, “SIM1”, 2, 0, 0, 0, 0)

 

(Or, you could have a single plugin and reassign NDArrayAddress depending on which one you want to deal with).

 

Similarly, the 3 StdArray plugins would be the following, which is what you pasted below:

 

NDStdArraysConfigure(“Image1", 200, 0, "SIM1", 0, 0, 0, 0, 0)

NDStdArraysConfigure(“Image2", 200, 0, "SIM1", 1, 0, 0, 0, 0)

NDStdArraysConfigure(“Image", 200, 0, "SIM1", 2, 0, 0, 0, 0)

 

And when you instantiate the database template files, NDARRAY_ADDR would be set to 0, 1 or 2 (not the ADDR, which would stay at 0). So I think the example for NDStdArrays.template which you pasted below might be wrong. The ADDR parameter is the address used by the Asyn port for the plugin itself (to set and read parameters in the plugin), rather than the address of the port used for the NDArray callbacks.

 

Also, if you are using autosave, you might want to delete or rename the autosave file (between IOC reboots) because that can be confusing for complex areaDetector applications if you’ve been trying out different port names and addresses.

 

Cheers,

I found this in the st.cmd file that i think helps in the discussion:

# mobipixConfig(const char *portName, int maxSizeX, int maxSizeY, int dataType,

#                   int maxBuffers, int maxMemory, int priority, int stackSize)

mobipixConfig("SIM1", 512, 512, 3, 0, 0)

#... a few lines after:

 

dbLoadRecords("NDStdArrays.template", "P=MOBICDTE:,R=image:,PORT=Image,ADDR=2,TIMEOUT=2,NDARRAY_PORT=SIM1,TYPE=Int16,FTVL=SHORT,NELEMENTS=12000000")

But im still kinda lost.

Hi,

 

I think you need to chain the plugins together, rather than have them all point to SIM1.

 

If you modify the StdArray plugins to register for callbacks from TRANS1, it should work.

 

For example:

SIM1->TRANS1->Image

 

The HDF plugin can either point to the SIM1 or TRANS1, depending on if you want the saved image rotated or not.

 

Cheers,

Matt

Hello all.

Im implementing the NDTransform plugin for an areaDetector IOC made here and following these documentations for this: hxxps://areadetector.github.io/master/ADCore/NDPluginTransform.html# hxxps://areadetector.github.io/master/ADCore/NDPluginDriver.html and hxxps://areadetector.github.io/master/ADCore/NDPluginTransform.html#.

Basically, i want a given image to rotate by 90 degrees and the documentation made me believe that this shouldnt be much trouble. The Array i want to rotate is a PV called MOBICDTE:image:ArrayData. I currently load the plugins via standard plugin file: commonPlugins.cmd inside ADCore and it seems to work since we are saving files in hdf5 format with the HDF plugin. The HDF plugin was also loaded with default macros from commonPlugins.cmd.

However, when i try to rotate the image by doing:

dbpf MOBICDTE:Trans1:EnableCallbacks 1

dbpf MOBICDTE:Trans1:Type 1

simply nothing changes in my visualizer when i start acquisition. I tried changing the configurations in the default commonPlugins.cmd file and comparing them with MOBICDTE:image paramaters but im not getting any luck with this. Does anyone have any tips on how to proceed?

What i tried so far:

The initial configurations were as follows:

 

NDStdArraysConfigure("Image1", 200, 0, "SIM1", 0, 0, 0, 0, 0, 5)

NDStdArraysConfigure("Image2", 200, 0, "SIM1", 1, 0, 0, 0, 0, 5)

# *** image is a combined image of image1 and image2***

NDStdArraysConfigure("Image", 200, 0, "SIM1", 2, 0, 0, 0, 0, 5)

 

dbLoadRecords("NDStdArrays.template", "P=MOBICDTE:,R=image1:,PORT=Image1,ADDR=0,TIMEOUT=2,NDARRAY_PORT=SIM1,TYPE=Int16,FTVL=SHORT,NELEMENTS=12000000")

dbLoadRecords("NDStdArrays.template", "P=MOBICDTE:,R=image2:,PORT=Image2,ADDR=1,TIMEOUT=2,NDARRAY_PORT=SIM1,TYPE=Int16,FTVL=SHORT,NELEMENTS=12000000")

# *** combined image ***

dbLoadRecords("NDStdArrays.template", "P=MOBICDTE:,R=image:,PORT=Image,ADDR=2,TIMEOUT=2,NDARRAY_PORT=SIM1,TYPE=Int16,FTVL=SHORT,NELEMENTS=12000000")

 

... #Then elsewhere, from the commonPlugins.cmd file:

NDTransformConfigure("TRANS1", 200, 0, "SIM1", 0, 0, 0, 0, 0, 4)

dbLoadRecords("NDTransform.template", "P=MOBICDTE:,R=Trans1:,  PORT=TRANS1,ADDR=0,TIMEOUT=1,NDARRAY_PORT=SIM1")

 

and by dbgf i could see that:

MOBICDTE:image:PluginType_RBV = NDPluginStdArrays
MOBICDTE:Trans1:PlguinType_RBV = NDPluginTransform

MOBICDTE:image:NDArrayPort_RBV = SIM1
MOBICDTE:Trans1:ArrayPort_RBV = SIM1

 

MOBICDTE:image:NDArrayAddress_RBV = 0x2
MOBICDTE:Trans1:NDArrayAddress_RBV = 0x0

 

MOBICDTE:image:QueueSize_RBV = 0xc8
MOBICDTE:Trans1:QueueSize_RBV = 0xc8

 

MOBICDTE:image:MaxThreads_RBV = 0x5
MOBICDTE:Trans1:MaxThreads_RBV = 0x4

So i thought i should change Trans1:NDArrayAddress to 0x2 by dbpf. Not only it did not work, but i also noticed that

 

MOBICDTE:HDF1:NDArrayAddress = 0x0

 

And the HDF plugin works fine, so i dont think the problem is the address anymore.

Am i doing something wrong? Im quite new to this plugin concept when applied to Area Detector. Thanks in advance for any help.
