  • @mpromonet I'd say it's not a duplicate in the sense that the OP seems satisfied with fbcp, whereas your question is explicitly about how to do this without that. Commented Nov 21, 2015 at 10:22

    Realistically speaking, SPI is the wrong interface for motion video, and absent access to the propriety GPU programming information you are probably not going to be able to be able to efficiently drive it (it is unclear if it would be possible even with such information). Ultimately you should choose an LCD and SoC which are natively comptible with each other - there are many tablet chips on the market which support parallel RGB interfaces for cheap LCDs.

  • @ChrisStratton Thanks for the comment. I'm not very experienced on this side yet. I'm guessing the [Raspberry Pi display on DSI ](swag.raspberrypi.org/products/…) is probably better, but was looking quickly for something that fits perfectly on top, so the 3.5" made sense in terms of look. Any hints on how I can find 3.5" displays that are natively compatible as you suggest ? Commented Nov 30, 2015 at 1:05

    My impression is that the problem is the pi, not the display. Something like the CHIP should be compatible with a cheap display, time will tell if it is a practical and supported product as implied or not, but there are many other SoCs similar and better to what it uses if not. If you want to stick with a pi, you should probably spring for a cheap HDMI display, or else buy the one matching its less usual LCD interface. Commented Nov 30, 2015 at 1:06

    Compare their data sheets to see if they have a common interface, for example 18/24 bit RGB. If so, see if they are parts you can work with - sufficient documentation, software support, and ability to buy them in quantities/forms usable for you (ie, bare chips if you want to make boards, evaluation or repurposeable boards if you don't). Typically the cheapest way to get a compatible SoC and display is to buy them together as a tablet. Commented Nov 30, 2015 at 17:13
