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_StreamCommand <https://github.com/Dennis-van-Gils/DvG_StreamCommand>_ it allows for automatically connecting to your Arduino(-like) device and for easy serial I/O communication.

• Separate PyQt/PySide interfaces are provided for each of these devices, offering out-of-the-box multithreaded data acquisition and communication. It relies on DvG_QDeviceIO <https://python-dvg-qdeviceio.readthedocs.io>_.

• Ready-to-run PyQt/PySide demos to directly control many of the supported devices with a graphical user-interface.

Changelog

1.3.0 (2023-02-23)

• Added method BaseDevice.SerialDevice.query_bytes()
• Fixed type hints in BaseDevice.SerialDevice

1.2.0 (2022-09-14)

• Added support for PyQt5, PyQt6, PySide2 and PySide6

1.1.0 (2022-02-01)

• Added method BaseDevice.SerialDevice.readline()

1.0.0 (2021-07-02)

• Stable release, identical to v0.2.6

0.2.6 (2021-03-02)

• Minor: Adjusted width of GUI control in Julabo_circulator_qdev.py

0.2.5 (2021-03-02)

• Loosened dependence to pyserial~= 3.4

0.2.4 (2021-03-02)

• Added device: Julabo circulator

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)
