Testing raw DPI display capability on the Raspberry Pi 2, Model B and B+ – (video) @raspberry_pi #raspberrypi

Testing raw DPI display capability on the Raspberry Pi 2, Model B and B+ – (video). 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 🙂

  1. God bless you Ladyada. I’m hoping we find ways to use this with something like RetroPie so we can make cooler portables with the pi. Maybe that isn’t the noblest of causes but oh well…

  2. Oh my, Can you post any more details?

  3. Hi, I’ve just subscribed to your youtube channel yesterday as I’m planning a big project involving Pi’s – I’m learning as I’m doing with it!
    I’m really interested in this video as I’m building a mobile pi and a nice touch screen would be perfect. You mentioned in the video (and the text) about “wiring up a break out”, I don’t suppose you could elaborate a little for me please? I’ve got a dead ployer momo9 iii tablet but the screen is fine, do you think it would be possible to use this screen with maybe a Pi a+ or B+?

    Wow, i wanted to try this but got stuck when i realised that the VGA666 lacks a dot/pixel clock signal and data enable signal. You just proved there is one or you don’t need one.
    Excellent work!
