204 And run ``systemctl enable restart-cec-inputattach``.
206 To automatically set the physical address of the CEC device whenever the
207 EDID changes, you can use ``cec-ctl`` with the ``-E`` option::
209 cec-ctl -E /sys/class/drm/card0-DP-1/edid
211 This assumes the dongle is connected to the card0-DP-1 output (``xrandr`` will tell
215 To automatically run this command you can use cron. Edit crontab with
216 ``crontab -e`` and add this line::
218 @reboot /usr/local/bin/cec-ctl -E /sys/class/drm/card0-DP-1/edid
230 adapters can support this. An example is the Odroid-U3 SBC that has a
231 level-shifter that is powered off when the HPD signal is low, thus
233 the level-shifter will prevent this from functioning.
236 If set, then the hardware cannot wake up displays with this behavior.
247 1) Get a Pulse-Eight USB CEC dongle, connect an HDMI cable from your
248 device to the Pulse-Eight, but do not connect the Pulse-Eight to
251 Now configure the Pulse-Eight dongle::
253 cec-ctl -p0.0.0.0 --tv
257 sudo cec-ctl -M
261 cec-ctl --playback
264 command::
266 cec-ctl -t0 --image-view-on
268 The Pulse-Eight should see the <Image View On> message. If not,
273 Pulse-Eight to a CEC-enabled display and run the same command
274 on your device: now there is a HPD, so you should see the command
275 arriving at the Pulse-Eight.

346 This device tree addition in ``arch/arm/boot/dts/bcm2711-rpi-4-b.dts``
347 will hook up the cec-gpio driver correctly::

359 hpd-gpios = <&gpio 12 GPIO_ACTIVE_HIGH>;
360 v5-gpios = <&gpio 22 GPIO_ACTIVE_HIGH>;
372 The minimum configuration is one HDMI female-female passthrough connector
373 and two female-female breadboard wires: one for connecting the HDMI ground
379 ``cec-ctl --monitor-pin`` will do low-level CEC bus sniffing and analysis.
380 You can also store the CEC traffic to file using ``--store-pin`` and analyze
381 it later using ``--analyze-pin``.
383 You can also use this as a full-fledged CEC device by configuring it
384 using ``cec-ctl --tv -p0.0.0.0`` or ``cec-ctl --playback -p1.0.0.0``.
407 ``vendor_id`` is set. In that case the driver controls CEC and CEC messages
