Revision 1594, 4.8 kB (checked in by jwoithe, 15 years ago)

RME driver:

  • add some missing status bit defines, fix naming of some others
  • add full decoding of device status registers
  • cache device run status
  • take external clock rates and device run status into account when evaluating the validity of sampling rates
  • minor bugfixes
  • implement function to configure a fixed DDS frequency on the device
