203 EDID changes, you can use ``cec-ctl`` with the ``-E`` option::
205 cec-ctl -E /sys/class/drm/card0-DP-1/edid
207 This assumes the dongle is connected to the card0-DP-1 output (``xrandr`` will tell
212 ``crontab -e`` and add this line::
214 @reboot /usr/local/bin/cec-ctl -E /sys/class/drm/card0-DP-1/edid
226 adapters can support this. An example is the Odroid-U3 SBC that has a
227 level-shifter that is powered off when the HPD signal is low, thus
229 the level-shifter will prevent this from functioning.
243 1) Get a Pulse-Eight USB CEC dongle, connect an HDMI cable from your
244 device to the Pulse-Eight, but do not connect the Pulse-Eight to
247 Now configure the Pulse-Eight dongle::
249 cec-ctl -p0.0.0.0 --tv
253 sudo cec-ctl -M
257 cec-ctl --playback
262 cec-ctl -t0 --image-view-on
264 The Pulse-Eight should see the <Image View On> message. If not,
269 Pulse-Eight to a CEC-enabled display and run the same command

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

355 hpd-gpios = <&gpio 12 GPIO_ACTIVE_HIGH>;
356 v5-gpios = <&gpio 22 GPIO_ACTIVE_HIGH>;
368 The minimum configuration is one HDMI female-female passthrough connector
369 and two female-female breadboard wires: one for connecting the HDMI ground
375 ``cec-ctl --monitor-pin`` will do low-level CEC bus sniffing and analysis.
376 You can also store the CEC traffic to file using ``--store-pin`` and analyze
377 it later using ``--analyze-pin``.
379 You can also use this as a full-fledged CEC device by configuring it
380 using ``cec-ctl --tv -p0.0.0.0`` or ``cec-ctl --playback -p1.0.0.0``.
