Hey all. I'm trying to use my TV remote to control my Shield via CEC, and I'd like to customize what key does what (for example, I'd like to reprogram the Record key to act as a Home key, since Record is all but useless and my remote doesn't have a button that acts as Home). Would this be possible?
Nope. CEC will function however each manufacturer programmed it to, which seems to be anywhere from 10 to 90 percent of what you would hope to control, and even then not consistently.
What you can do, though, is get a FLIRC - it's a USB IR receiver dongle you can program on your computer to receive signals from whatever remote you have and interpret that as a simulated keyboard button. When you move the FLIRC to your shield it will keep the commands in memory and act as if a keyboard were plugged in and the corresponding button was pressed.
