2. New Features
===============
Client
------
1. Compilation requirements
They are very different now and can be accessed at
https://slsdetectorgroup.github.io/devdoc/dependencies.html
Gui not included in default cmk.sh script. Must be explicitly asked for.
2. Manuals
They can be compiled in the package.
https://slsdetectorgroup.github.io/devdoc/installation.html#build-this-documentation
Or refer to the documentation provided in
https://slsdetectorgroup.github.io/devdoc/index.html
3. API
Changed to Detector class.
C++: Detector.h
Documentation:
https://slsdetectorgroup.github.io/devdoc/detector.html
Examples to use the Detector class:
https://github.com/slsdetectorgroup/api-examples
Python API Documentation:
https://slsdetectorgroup.github.io/devdoc/pydetector.html
Command line:
Many commands have become deprecated. They will still execute,
but give a warning.
Documentation:
https://slsdetectorgroup.github.io/devdoc/commandline.html
Help on a command:
sls_detector_help [command], or
sls_detector_get -h [command]
4. Exceptions
They are thrown instead of providing error codes.
sls_detector_exceptions.h
Make sure you catch all exceptions in custom gui and handle them or
inform the user.
Exceptions thrown in callbacks are also handled.
- An exception in startAcquisitionCallBack will need to be handled in
startReceiver or acquire()
- An exception in acquisitionFinishedCallBack will need to be handled in
stopReceiver or acquire()
- An exception in rawDataReadyCallBack or rawDataModifyReadyCallBack
will only print and skip image to free it in memory. If address is
incorrect after callback, expect undefined behavior.
5. Scan mode
One can do scans for dacs or trimbits. Trimbits are only for Eiger or
Mythen3. Enable scan mode and then acquire using blocking or non blocking
method. Command: scan.
6. Timing Commands
In command line, all timing commands (eg. peiod) can now specify unit.
eg 100ms 10us, 1s, 100ns
In C++ API, one must use chrono library.
eg. std::chrono::duration<double, std::milli> t1{232.57};
det.setExptime(std::chrono::duration_cast<std::chrono::nanoseconds>(t1));
In Python API, one must use timedelta library.
eg. d.exptime = dt.timedelta(seconds = 1.2)
7. Enum list (daclist)
Command line and API now has features to get the list of enums/commands
for dacs, settings, dynamic range, timing modes and temperatures for
the detector in shared memory.
eg. daclist, settingslist, drlist, timinglist, templist
Command line also has commands to get their values.
eg. dacvalues, tempvalues
Python has commands to get their values (detector specific class).
eg. d.temp, d.dacs
8. Command Line (return code)
Return code of the client command line applications now return 0 for
success and 1 for failure.
9. Command Line (Dac)
All dac commands have been converted to a single "dac" command with
the previous dac commands as arguments.
eg. sls_detector_get vcmp_ll
is now
sls_detector_get dac vcmp_ll
10. UDP Configuration
Once all the udp details are set in the detector, the detector's
destination is then configured automatically. If the detector is not
configured, it will fail when acquiring. If any of these parameters
are also changed, then this is configured again. Hence, configuremac
command has been removed. Instead, there are commands such as
udp_validate (to validate if it has been configured) and
udp_reconfigure (to reconfigure).
11. Gap Pixels
Gap pixels are now only available in client call back or gui (not in
receiver anymore). It can be enabled for Eiger and Jungfrau and
includes inter chip and inter module gap pixels.
Detector Servers
----------------
1. Detector Simulators
Or virtual detector servers for every detector have been provided.
They are compiled along with the client by enabling its option.
They should also send fake data (increasing pixel/channel value).
2. (Jungfrau) settings
Settings command do not implicitly set default dacs from now on.
One can use the command 'defaultdacs' to set them explicitly.
3. Shared Memory
Almost all the detector parameters removed from shared memory.
Therefore, they are all fetched directly from detector.
4. (Jungfrau) Two 10G data interfaces
Only Jungfrau PCBs with version 2.0 can run at full speed using both
the 10G UDP interfaces to stream out data. This is available from
the current firmware and software. To enable two interfaces, one has
to enable two interfaces using "numinterfaces" to 2 and set corresponding
udp_dstip2, udp_dstport2 etc. One can also decide to select which of
the two interfaces to use, when using only 1 interface.
5. (Eiger, Jungfrau) Next Frame number
Both now have running frame numbers that is only reset at boot up
and increments continuously through acquisitions. One is able to
set the next frame number now. Command: nextframenumber.
6. (Eiger) Server Config file (config_eiger.txt)
A config file on the detector can take in 2 parameters "master"
and "top" being set to 1 or 0 to enable or disable the same.
When server is started without this file, it is set to hardware
settings.
7. (Eiger) Partial readout
It is possible for partial readouts, where you specify the number
of pixel rows to read out. Not all values are allowed. The current
slsReceiver does not complain about missing packets, but only puts
this partial image into the complete image (padding the rest). One
can cut out required subimage using callbacks, but this feature
is probably more useful for custom receivers. Command: readnlines.
8. (Eiger) Removed Features
storeinram, safe speed and ability to set settings via the settings
command has been removed.
9. (Eiger) Deactivation
The detector is deactivated by default upon boot up and activated only
upon setting hostname in the client. This is to ensure if the
network of a board or a board is broken and one cannot connect
to this board, then it is deactivated by default upon reboot.
Therefore, one can use other half modules of the detector.
Receiver
--------
1. Zmq
The static library and the zmq.h is no longer provided with package.
One must install ZeroMQ version 4.
ZmqSocket.h API has changed, especially in parsing receiving JSON header.
One must pick up needed parameters from exposed struct zmqHeader in
ZmqSocket.h.
2. Metadata
Detector dependant metadata has been added to the master files.
3. Shared Memory
Almost all receiver parameters have been removed from client shared memory.
Therefore the receiver process needs to be alive to access any receiver
parameter as they are now fetched directly from the receiver.
4. UDP IP
Since all the parameters are fetched from receiver or detector directly
(not shared memory), the udp desintation ip (previously rx_udpip) is safer
to be specified before setting rx_hostname. Setting it before has the
advantage that the detector is updated first before the receiver is
requested for the udp mac. This helps when changing pc and the receiver
cannot find the udp ip to get the udp mac.
5. (Eiger) Header packet
The header packets of Eiger are not sent in this firmware version. So,
custom receivers should handle accordingly.
Gui
---
1. Zmq high water mark
When opening the Gui, the zmq send and receiver high water mark is set to 2
instead of default (1000 for zmq library version 4). This is to ensure
fast and large detectors can still see latest data on the gui at the cost of
losing images in between.
When using a different processor or client data call back to handle zmq data,
please ensure this is set back to default to get every zmq packet. Setting it to
-1 sets it to library defaults.
3. Resolved Issues
==================
Detector Server
---------------
1. (Eiger) Blocked Server
Very rarely, Eiger control or stop server would block and would require a restart
of server. This is due to both servers accessing the same link to get to FEB
registers. Locking has been implemented in server shared memory to resolve.
4. Known Issues
===============
1. (Eiger) Extra 8 byte Packets
When stopping detector acquisition while acquiring for more than 128 frames,
the next acquisition sends out first an 8 byte packet. This is discarded
by the slsReceiver/slsMultiReceiver. Please handle this in custom receivers.
