From aa3d4409b664813ceb86a24bd09458cdd29cbb8a Mon Sep 17 00:00:00 2001 From: Martin Kepplinger Date: Mon, 22 May 2017 17:19:45 -0700 Subject: Input: edt-ft5x06 - increase allowed data range for threshold parameter The datasheet and application note does not mention an allowed range for the M09_REGISTER_THRESHOLD parameter. One of our customers needs to set lower values than 20 and they seem to work just fine on EDT EP0xx0M09 with T5x06 touch. So, lacking a known lower limit, we increase the range for thresholds, and set the lower limit to 0. The documentation is updated accordingly.
