drivebox 0.1.1

API for the Caonabo DribeBox (CDB)

drivebox

Python API to interact with the Caonabo DriveBox (CDB). The Caonabo DriveBox is a tool that combines a switch matrix module with an itnernal potentiostat/Galvanostat in order to drive electrochemical (EC) reactions through diferent EC cells. The potentiostat/galvanostat module allows for the sourcing of potentials of ±7.5V and currents of ±65mA. The switch-matrix module allows to assign signals to a total of 50 electrodes. The signals can be procided from the internal potentiostat/galvanostat itself or from and exteral source. For ease of writing from her on we will refer to the potentiostat/galvanostat module as the Source Measurement Unit (SMU).

For more information regarding the CDB hardware please visit the hardware repository.

1 Installation and package dependencies

This packager requires the previous installation of the following packages:

• pyserial 3.5 (or newer)

Afer installing the dependencies, the package can be installed from the Python package index (PyPI) repository.

In Windows:

C:\> pip install --user drivebox

or in Linux:

$ pip install --user drivebox

If using the anaconda distribution for python you can also use the conda package manager for the instalation from the dreamwere channel.

In Windows:

C:\> conda install -c dreamwere drivebox

or in Linux:

$ conda install -c dreamwere drivebox

As an alternative, the drivebox package (inside the src/ folder) can be download and copied into the the main folder of the project where it will be used.

2 How to use the package

2.1 Instantiation, initiation and general commands for the CDB.

First, the module must be imported:

>>> from drivebox import board

Once imported, the cdb class inside the module must be instantatiated to gain control to an specific CDB. Hence, the port where the CDB board is connected, as well as the ID of the board, must be specified. For the port, the name of the port can be given such as "COM1" or "AUTO" can be used. Sometimes, "AUTO" might not work due to conflict with some USB devices. If this happens, the port will have to be passed manually. An example instantiations can be as folows:

>>> cdb = board.cdb(port="AUTO", board_id="000")

Once initiated, the following output will appear in the console:

Caonabo DriveBox (CDB) with correct ID initiated in port: COM10. Average measurement delay (For [V,I]): 170.0ms

At the end, the instance must be properly closed to avoid leaving the serial ports open. This is done by using the close() method:

>>> cdb.close()
