This section is about the Python library that interfaces with the SPI Rack. It takes care of the communication with the controller module and it contains all the code that sets up the modules correctly. Therefore this library is necessary for the SPI Rack to function. This does not mean that the SPI Rack cannot be used in a different framework. A basic interface for multiple modules has already been written for the Qcodes data acquisition framework: http://qcodes.github.io/Qcodes/.
Here a simple example on how to use the D5a (DAC) module to show how easy it is to get going:
# Import parts of the SPI Rack library
from spirack import SPI_rack, D5a_module
# Instantiate the controller module
spi = SPI_rack(port="COM4", baud=9600, timeout=1)
# Unlock the controller for communication to happen
spi.unlock()
# Instantiate the D5a module using the controller module
# and the correct module address
D5a = D5a_module(spi, module=2)
# Set the output of DAC 1 to the desired voltage
D5a.set_voltage(0, voltage=2.1)
More examples can be found in the example notebooks on GitHub or in the Examples section. The source code can be found at the GitHub page: https://github.com/mtiggelman/SPI-rack.
