Testing raw DPI display capability on the Raspberry Pi 2, Model B and B+

Did you know that the Broadcom processor on the Raspberry Pi can control a 'raw dotclock' type display? Well now you do! A Model B+ or Pi 2 Model B has enough pins for 18-bit color, and since it uses the graphics processor, its really fast. You just need to run the vga666 device tree overlay and wire up a breakout. I'm working on a HAT version too :)

*How To Use A DPI Display With A Raspberry Pi*

_Robert Ely has a great blog post about how to use a DPI (display parallel interface) display with the Raspberry Pi.  Check out the post to learn how to wire up the display and configure the Pi to output video to it just like it were a HDMI display.  Robert was inspired by Ladyada’s demonstration above and even used the TFT friend and a 5″ display from Adafruit for his project.  Nice work and great explanation of using a DPI display!_

_Let’s add a dirt cheap display to the Raspberry Pi B+_

Ok - this is cool. Well done Ms. Ladyada! I am looking forward to the hat...

The Raspberry Pi Foundation is working on releasing their DSI port Display accessory. No clue when it will be released though

I have actually been doing this for about a month with your 5" TFT and the TFT friend breakout. I am using 24 bits though. Well, 23 bits since I spent all my GPIOs except for I2C1 and needed an interrupt line for the touchscreen controller - which I will try to grab from the camera connector eventually, though.

Wow this is so cool! Do you know any 3.5" screen that can be interfaced via DPI?

I thought the GPIO pins were connected to the CPU, not the GPU. How does it use the graphics processor? Also does this mean you can render accelerated OpenGL to a display connected in this way?

Nice, where can I learn more about this specific project?
I want to build this but I run into problems when substituting hardware like the LCD then finding out later I wasted money on something new that isn't compatible or ends up being more work than desired to work around the substitution.

so this could mean that we could drive a standard laptop display at the recommended resolution straight from the pi2b without needing another driver board?

[MiguelAngelAjoPelayo]

Can't that be done via the digital display output in the board itself instead of running through SPI or GPIOs?

Hello, I would like to know if this is also possible for the BeagleBone black? If so, does anyone know which device tree I can use?
