Re: Custom HDMI modes

If I leave the Pi's settings alone, and either hotplug or boot with the Rift plugged in, I get Orange/Blue. If ...

Re: 7.4V/2S 1800mAh 20C LiPo battery for LCD and Raspberry P

Basically what you're looking for is a BEC. I have one of them in a camera unit, although I'm not completely sure that they're necessary with the Pi. Many devices can handle a fairly wide range of voltage without failing. There should be information out there about this.

Re: Custom HDMI modes

Hi Dom, from the sounds of it, you're the person to ask about my issue. I've been trying to connect my Rift DK2 to the Pi B+ for a few days now, and have tried almost every possible combination in config.txt. The DK2 is 1080x1920. It's not a rotated 1080p display. It's natively in portrait. Is there...

Re: Trouble with the Oculus Rift DK2

Still no one?

From what I can tell, the issue is that the Pi doesn't support native portrait resolutions. I really hope that this isn't the case!

Trouble with the Oculus Rift DK2

I am attempting to get the Oculus Rift DK2 to run straight off the Raspberry Pi B+ HDMI port and I'm running in to a bit of difficulty. The device detects it's preferred resolution as 640x480 @ 60Hz, which is a fair way off 1080x1920 @ 75Hz. I had to basically delete the contents of /boot/config.txt...
