Client API update v1.1.0

This update brings homogenized API for PulseStreamer clients in all supported languages. From now on, the signatures of all currently present functions and methods are frozen and will remain stable over the future minor updates and releases. In the future, we plan to add any new functionality in a backwards compatible way with no user code modifications required.

  • The API was slightly redesigned and homogenized in all supported languages.
  • The use of high-level clients is now a recommended way of programming and streaming the pulse sequences with the Pulse Streamer.
  • New methods PulseStreamer.createSequence and PulseStreamer.createOutputState that create hardware specific Sequence and OutputState objects.
  • New method PulseStreamer.getFPGAID.
  • New OutputState class for defining the state of Pulse Streamer outputs in some methods.
  • New OutputState.ZERO constant.
  • New named constant PulseStreamer.REPEAT_INFINITELY = -1 for infinite sequence repetition.
  • Sequence object now applies padding to the pattern data and previous previous levels on concatenation.
  • Renamed enum TriggerMode to TriggerRearm, also renamed enumeration values.
  • Renamed enumeration values in enums TriggerStart.
  • Modified signature of the PulseStreamer.getSerial() method which now has no input parameter and always returns hardware serial number.

Matlab

  • The client code is now distributed as a packaged Matlab Toolbox.
  • Now the PulseStreamer client is placed into its own namespace PulseStreamer in order to prevent possible collisions in function names. You can use import PulseStreamer.* to shorten the class names.
  • Moved compatibility functions for FW v0.9 to PulseStreamer.compat sub-package.
  • Sequence.setDigital and Sequence.setAnalog allows for overwriting mapped pulse patterns even after concatenation or repetition.
  • PulseStreamer.stream() method now supports Sequence object and [{duration,chan_list,a0,a1}; {...}] cell array as input.
  • Functionality of PSSequenceBuilder and PSSequence classes is now combined and moved to Sequence class.
  • Renamed PSTriggerMode to TriggerRearm.
  • Renamed PSTriggerStart to TriggerStart.
  • Renamed PSSequence to Sequence.
  • Removed PSSerial enum.
  • Sequence.plot method plots the sequence data exactly as defined by user without resampling to common time.
  • Sequence is completely decoupled from PulseStreamer class. Use PulseStreamer.createSequence() method to create a Sequence object that does early channel number validation.
  • Helper classes like PulseStreamer_Dummy and PulseStreamer_RPCLogger located in a sub-package PulseStreamer.debug.
  • Solved problem with multiple timers created on repeated script runs with long sequences. Only one timer can exist for a given device.

LabView

  • Pulse Streamer client code for LabView is now distributed as a VIPM package.
  • Functionality of SequenceBuilder and Sequence classes is now combined into Sequence class.
  • Added Sequence:plot.vi which plots the pulse patterns according to user input with no resampling to common time.
  • PulseStreamer:stream.vi method is a polymorphic VI with wrappers to handle implementation VIs with dynamic inputs.
  • PulseStreamer:stream.vi supports Sequence object, old Pulse array, and RLEdata cluster as inputs.
  • Renamed Digital Pattern.lvclass to PulsePattern.lvclass.
  • Renamed Analog Pattern.lvclass to AnalogPattern.lvclass.

Python

  • PulseStreamer client is distributed as wheel package pulsestreamer.
  • PulseStreamer now uses standard tinyrpc package instead of previously used customized version tinyrpc3.py. Use pip install tinyrpc to install the package, if missing.
  • Some changes in parameter names. Please see Programming interface.
  • New concatenate, repeat and `plot methods are added to Sequence class.
  • PulseStreamer client is organized into a python module with cleaner layout.
  • PulseStreamer.stream method accepts Sequence object as input parameter directly.
