Actually, there's no problem. You can get it to do what you want by explicitly specifying the rx mux value. To feed both A side inputs into the DDC 0 as I & Q, do u.set_mux(0x10101010) /*! * \brief Set input mux configuration. * * This determines which ADC (or constant zero) is connected to * each DDC input.
