News: hkl-lib; lambda; set_pos; pyspectra and hasyutils new version

• install new hkl-lib, request from P09:

   
  The new version of the library offers to calculate 2 vectors: ki and kf
  With these modifications it is possible to make a calculation like this:
  
  -------------------------------------------------
  def get_kinc_kscat(config, values):
      sample, detector, geometry, engines = new_hkl_diffractometer(config)
      geometry.axis_values_set(values, Hkl.UnitEnum.USER)
      R = hkl_matrix_to_numpy(geometry.sample_rotation_get(sample).to_matrix())
      UB = hkl_matrix_to_numpy(sample.UB_get())
      RUB = dot(R, UB)
      RUB_1 = inv(RUB)
  
      ki = geometry.ki_get()
      kinc = dot(RUB_1, ki.data)
  
      kf = geometry.kf_get(detector)
      kscat = dot(RUB_1, kf.data)
      return kinc, kscat
  

  Implementation options:

  • Extend the controller attributes?
  • Change SPEC recorder?

  The new hkl-lib needs careful testing.

• Lambda, new versions: (LambdaCtrl-v2.12, LambdaRecv-v2.7)
  • Added Retry if first StartAcq command gets timeout, this is a fix for old Lambda modules, loan pool, P08, P23, P64.
  • Added attribute StreamCounter which shows the number of messages have been sent to ASAPO if ASAPO is enabled This is used to show whether there is an issue of sending messages

• set_pos 'issue': recently it has been reported that the set_pos macro resulted in motor movement sporadically. Reason: polling period of the position attribute was set to 50 msec, should be disabled.

• hasyutils, pyspectra, new versions:
  • Bug fix for pyspMonitor: double-click on file name in FilesListWidget works again
  • Added feature: toPyspMonitor( ..., singleMonitor = False) , can be set to True to avoid I/O with the Macroserver to read RegisteredPyspMonitors. Details can be found here
