If +you want to use a hack in a different driver, please fix the +hack instead of duplicating it. + + +- Extended configuration: the daqboard2000 driver loads about + 40 kB of FPGA programming information at device configuration. + It does this by overloading option[0] and option[1] with the + address and length of the programming data. A corresponding + hack in comedi_config allows one to specify a file to be loaded + as the FPGA data. Fix: change the devconfig interface to + make this standard. + +- Autocalibration input: the ni_mio_common driver uses AREF_OTHER + to access stable voltage references on the board. It's not the + best method, but it is only supposed to be accessed by + comedi_calibrate. + + -- 2.26.2
