From 45b77828b01cdf2af655e4edbc63646fc7e07b48 Mon Sep 17 00:00:00 2001 From: Jonathan Cameron Date: Sun, 14 Mar 2021 18:14:57 +0000 Subject: iio:event: Add timeout event info type For adaptive threshold events, the current value is compared with a (typically) low pass filtered version of the same signal that slowly tracks large scale changes. However, sometimes a step change can result in a large lag before the low pass filtered version begins to track the signal again. Timeouts can be used to made an instantaneous 'correction'. Documentation of this attribute is added in a later patch.
