I am using a 3.8 custom kernel for Intel Galileo. I could successfully interface the AD7606 eval as a SPI platform device and was able to read samples using sysfs entries.
1. I would like to know how I can acquire data by setting a constant sampling frequency for CONVST pin.
2. I went through the link "http://wiki.analog.com/resources/tools-software/linux-drivers/iio-adc/ad7606" tried setting sysfs triggers & buffers but didn't see any options for setting the frequency.
3. Where is the final buffer from which I can read the sampled values?
