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.
