From af9a96d23eda3c9989e8b80c9ad2a9c41334aefd Mon Sep 17 00:00:00 2001 From: =?utf8?q?Torbj=C3=B6rn=20Jansson?= Date: Mon, 30 Jul 2018 15:59:20 +0200 Subject: [PATCH] kernel: add kmod-iio-htu21 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This adds support for the htu21 humidity and temperature sensor. To get it to work you have to do something like this: echo "htu21 0x40" >/sys/class/i2c-dev/i2c-1/device/new_device for example by adding it to rc.local Compile tested on brcm2708 and I have used an earlier version of this patch for more than a year.
