B.37 Simple Field Control (HJS_SFC, Steinhoff group, Osnabrueck)

Module name: hjs_sfc

Additionally required module: hjs_daadc

Description: Pseudo-device module used for controlling magnets in the group of H.-J. Steinhoff at the University of Osnabrueck. It's not for a device that gets controlled directly by this module but instead the magnetic field is controlled indirectly via the output voltage of a home-built DA and AD converter, using the module hjs_daadc. The module requires a previous calibration of the relation of the DAC output voltage and the resulting field, with these data getting set in the configuration file for the module. Because there's no gaussmeter to control the real field only this calibration can be used. When this module is used the DAC of the DA and AD converter can't be used, it gets reserved automatically for this module.
