Subject: DMA sampling and IIO
Date: Wed, 05 Feb 2014 10:42:20 -0800 [thread overview]
Message-ID: <CF17C5B7.1940A%john3909@gmail.com> (raw)
I¹m working on a project that uses the ADE7878 Energy Measurement part
from Analog Devices. Currently there is an IIO device driver in the
staging/iio/meter folder, but I would like to extend this by adding high
speed sampling of the AC waveforms. The ADE7878 will continuously output
samples (8 Khz) of the voltage/current waveforms via an I2S interface. I
plan to use DMA to store these values in a buffer and then use IIO Ring
Buffer to access these values from User Space.
Was this considered in the IIO framework and does anyone have any
suggestions on how I might proceed?
Jonathan Cameron suggested I include Lars-Peter Clausen and Mark Brown in
this discussion.
Regards,
John
