Hi everyone, I hope this is the right place to ask my noob question. I'm trying to learn how to write an IIO driver and using a couple books as my resource. I managed to write a simple one and perform oneshot-based data reads (e.g. cat iio:device0/in_temp_raw). Now, I'm trying to set up a trigger-buffered data read. I believe I set up the triggers correctly: cat trigger0/name > iio:device0/trigger/current_trigger echo 1 > iio:device0/scan_elements/in_temp_en echo 1 > iio:device0/buffer/enable cat /dev/iio\:device0 | xxd - Now, I'm not understanding how I should actually perform the trigger. >From my books, there should be a trigger_now file where I can echo 1 to trigger, but it's not available in my trigger0/ directory. Also, the book references a add_trigger in /sys/devices/iio_sysfs_trigger/ directory, but that's nowhere to be found as well. My .config also has CONFIG_IIO_SYSFS_TRIGGER=m. Any help/advice would be appreciated! Thanks, William Huang
