Resolved! Is it possible to achieve an ADC sampling rate of 500ksps and more via the iio interface, and if yes, how?
Hi all,I followed the instructions described on the wiki, page ADC_device_tree_configuration.Changing the sampling_frequency, I can achieve a sampling rate of about 10k. Going higher crashes the system. Reducing the parameter 'min-sample-time-nsecs' ...
