DvG_Devices

Collection of I/O interfaces to communicate with microcontroller boards and laboratory devices, with optional PyQt5 multithread support and graphical user-interfaces.

Installation:

pip install dvg-devices

Supported devices

Arduino, or similar microcontroller board
Aim TTi QL series II power supply
Bronkhorst EL-FLOW mass flow controller
Parker Compax3 servo controller
Keysight 3497xA digital multimeter
Keysight N8700 power supply
Picotech PT104 temperature logger
PolyScience PD recirculating bath
ThermoFisher ThermoFlex chiller

Highlights

  • Class SerialDevice() offering higher-level general I/O methods for a serial device, such as auto_connect(), write() and query().
  • Class Arduino() which wraps around SerialDevice(). In combination with DvG_SerialCommand it allows for automatically connecting to your Arduino(-like) device and for easy serial I/O communication.
  • Separate PyQt5 interfaces are provided for each of these devices, offering out-of-the-box multithreaded data acquisition and communication. It relies on DvG_QDeviceIO.
  • Ready-to-run PyQt5 demos to directly control many of the supported devices with a graphical user-interface.

Changelog

0.2.3 (2020-08-27)

  • Workaround for bug with unknown cause in Aim_TTi_PSU_protocol_RS232 where the power supply occasionally will skew the serial input and output stream, such that the reply matches the second-previous query statement. Fixed by forcefully flushing the serial input and output buffers whenever a wrong reply is received. Hopefully, this will fix the skew when the next query() operation gets executed.

0.2.2 (2020-08-27)

  • Fixed bug in BaseDevice.query_ascii(). The use of ast.literal_eval got removed because it chokes on nan. Everything is now interpreted as a float instead.

0.2.1 (2020-08-12)

  • Fix wrong import statement dvg-pyqt-controls
  • Fix wrong import statement dvg-pyqt-filelogger

0.2.0 (2020-08-11)

  • Added dependence dvg-pyqt-controls~=1.0
  • Added dependence dvg-pyqt-filelogger~=1.0
  • Added dependence dvg-pyqtgraph-threadsafe~=3.0

0.1.0 (2020-07-23)

  • Fixed bug in BaseDevice.py where inspect.getouterframes() would momentarily suspend the thread. Solved by ditching inspect. The new ID_validation_query mechanism now relies on a simple boolean flag that gets set to force query() to raise on timeout.
  • Update dependence dvg-qdeviceio==0.3.0

0.0.7 (2020-07-17)

  • Update dependence dvg-qdeviceio==0.2.2

0.0.6 (2020-07-16)

  • Finished implementing BaseDevice.SerialDevice()
  • Update dependence dvg-qdeviceio==0.2.1

0.0.5 (2020-07-07)

  • Update dependence dvg-qdeviceio==0.2.0 Enum DAQ_trigger is now called DAQ_TRIGGER
  • Code style: Black

0.0.4 (2020-07-04)

  • Update dependence dvg-qdeviceio==0.1.2

0.0.3 (2020-07-02)

  • Fixed broken packaging

0.0.2 (2020-07-02)

  • Major restructuring PyPI package
  • Implemented DvG_QDeviceIO

0.0.1 (2020-07-01)

  • First release on PyPI
