- Using Overlays
- ==============
-
--Overlays are loaded using the "dtoverlay" directive. As an example, consider
--the popular lirc-rpi module, the Linux Infrared Remote Control driver. In the
--pre-DT world this would be loaded from /etc/modules, with an explicit
--"modprobe lirc-rpi" command, or programmatically by lircd. With DT enabled,
--this becomes a line in config.txt:
--
-- dtoverlay=lirc-rpi
--
--This causes the file /boot/overlays/lirc-rpi.dtbo to be loaded. By
--default it will use GPIOs 17 (out) and 18 (in), but this can be modified using
--DT parameters:
--
-- dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=13
--
--Parameters always have default values, although in some cases (e.g. "w1-gpio")
--it is necessary to provided multiple overlays in order to get the desired
--behaviour. See the list of overlays below for a description of the parameters
-+Overlays are loaded using the "dtoverlay" config.txt setting. As an example,
-+consider I2C Real Time Clock drivers. In the pre-DT world these would be loaded
-+by writing a magic string comprising a device identifier and an I2C address to
-+a special file in /sys/class/i2c-adapter, having first loaded the driver for
-+the I2C interface and the RTC device - something like this:
-+
-+ modprobe i2c-bcm2835
-+ modprobe rtc-ds1307
-+ echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
-+
-+With DT enabled, this becomes a line in config.txt:
-+
-+ dtoverlay=i2c-rtc,ds1307
-+
-+This causes the file /boot/overlays/i2c-rtc.dtbo to be loaded and a "node"
-+describing the DS1307 I2C device to be added to the Device Tree for the Pi. By
-+default it usees address 0x68, but this can be modified with an additional DT
-+parameter:
-+
-+ dtoverlay=i2c-rtc,ds1307,addr=0x68
-+
-+Parameters usually have default values, although certain parameters are
-+mandatory. See the list of overlays below for a description of the parameters
- and their defaults.
