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
