I want to create a timer to automatically trigger the iio driver ADC conversions, rather than having it triggered by sysfs reads. How does one go about that?
Looking at the module characteristics I believe this can be accomplished by using the DELAY feature to trigger the same or other channels periodically, The rate seems to be up to 2KHz.
But I believe this feature is not implemented in the Linux driver.
This discussion has a very good example of a community member LRADC with IMX28 That can be useful to implement your own driver.
