[PROBLEM] CEC (new to this..)

[raspberry_pd]

HDMI-CEC is effectively a single pin/wire in the HDMI cable spec that is dedicated to allowing HDMI devices to send control signals to each other.

For example, button events from a HDMI device's remote control can be relayed or sent to another HDMI device.

In your case, some button events from your projector's remote control may be passed on or relayed to the Raspi and XBMC, potentially allowing your to interact with XBMC without the need for a secondary remote control. With a bit of luck, you may want to list that expensive Harmony remote on eBay soon

Is this your unit and projector and remote control ?



If so you are probably in luck. The main buttons needed to control XBMC via CEC are up/down, left/right, enter or OK and a back button. It appears that your remote control has most of those however there is no guarantee that the button events will be passed through the CEC wire from your projector to the Raspi. In most cases, only a subset of buttons events are passed through.

For an indication of what features are available through CEC, check out this table:

Pulse Eight is the company that writes the CEC library used to make the CEC adaptor you have seen in the Peripherals section of XBMC.

You can remap the button events that your remote control does send through to the Raspi if needed.
