The frequency generator allows anexternal complex impedance to be excited with a known frequency.The response signal from the impedance is sampled by the on-board ADCand a discrete Fourier transform (DFT) is processed by an on-chip DSP engine.The DFT algorithm returns a real (R) and imaginary (I) data-word at eachoutput frequency.Changes since V1:Apply list review feedback:Consistently use poll_time_jiffies.Use be|le cpu endian helpers where applicable.Add various comments.Changes since V2:Fix KernelVersion tag in Documentation.Declare ad5933_default_pdata static.Fix typos.Signed-off-by: Michael Hennerich <michael.hennerich@analog.com>Acked-by: Jonathan Cameron <jic23@cam.ac.uk>Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> List of files: /linux-6.15/drivers/staging/iio/impedance-analyzer/Makefile Tue, 02 Aug 2011 06:48:22 +0000 Michael Hennerich <michael.hennerich@analog.com>
