This release features some bug fixes for the Toptica Topmode, multicharacter termination string support, and the ability to open a serial connection via Instrument.open_serial with USB identification numbers to better support USB-to-Serial adapters.

Change Log

New Features

General

  • Support for multicharacter termination strings. Some instruments use Windows-style line endings (\r\n) as their end-of-string signal. These changes allow serial, socket, and loopback connections to now use arbitrary length line endings. For VXI11 connections, a warning is raised since the parent library (python-vxi11) only ends up using the first character of the termination string provided. Other connections previously supported multicharacter termination (for example, Instrument.open_gpibusb supported \r\n) so now everything should be more in line.
  • One can now open a connection via Instrument.open_serial with the USB identification numbers (VID, PID, and serial number). This allows for more easier and consistent operation with instruments that use some sort of USB-to-Serial conversion. By specifying these identifiers instead of the COM port (ie, COM4, /dev/ttyUSB0, /dev/ttyACM0, etc, depending on platform and vendor) you can be confident that your software will continue to work, even if the virtual serial port name changes.

Toptica Topmode

  • adding the udev rule
  • adding firmware and topmode charm controller serial number
  • adds the ability to query the firmware and serial number of the charm controller (not to be confused with the serial number of the laser)

Bug Fixes

Toptica Topmode

  • fixing a command spelling error
  • handling the situation when no laser is plugged into the controller
  • module now uses multichar \r\n instead of \n with string manipulations
  • laser.lock_start, property checks whether the lock has successfully completed or is in process before returning the start time so that empty dates are not returned.
  • laser.first_mode_hop_time and laser.latest_mode_hop_time properties check whether a mode hop has been detected before querying these times so that empty dates are not returned.
  • removes the runtime error from laser.is_connected property. If the laser is not connected, it simply returns false.
  • fixes the date format of the dates returned by the charm controller.
