How to install
Clone this git repository or download the repository as a zip package and extract. Then, from the root folder of the repository, run
$ python setup.py install
Depending on your setup and environment, you might want to consider doing so inside a virtualenv.
This package only has a single requirement (which is automatically installed when running the above command):
pyserial library provides access to the serial port and is implemented in pure Python.
In other words: This driver does not use any C extensions and should work in many Python implementations.
How to run unit tests
From the root folder of the repo, run:
$ python -m unittest
No additional dependencies are required.
Currently, this library aims to implement all features documented in the MS3device user manual (with exceptions listed below).
Not (yet) supported features
The configuration settings listed below are not currently implemented in this library:
- For the Host Port Protocol setting, the values "Multidrop", "User Defined", and "User Defined Multidrop"
- Matchcode (all functionality described in chapter 7 of the user manual)
- Configuration settings for the Codabar, Interleaved2Of5, and Pharmacode symbologies
A workaround for applications that require these features, is to send the corresponding configuration strings directly using the
MicroscanDriver.write() method, for example, to only output symbol data on match, but as soon as data is available:
driver = MicroscanDriver('COM3') driver.write(b'<K705,1,0>') driver.close()
No sanity checking is performed on the combinations of settings in a configuration. Only individual settings and their subsettings are (to limited degree) validated against the specification.
