From 27be84236d75c13a83c45d850390f40b58401d97 Mon Sep 17 00:00:00 2001 From: Irina Tirdea Date: Sun, 11 Jan 2015 21:10:11 +0200 Subject: iio: core: Introduce CHANGE event type A step detector will generate an interrupt each time N step are detected. A device that has such pedometer functionality is Freescale's MMA9553L: http://www.freescale.com/files/sensors/doc/ref_manual/MMA9553LSWRM.pdf. Introduce IIO_EV_TYPE_CHANGE event type for events that are generated when the channel passes a threshold on the absolute change in value.
