5.0" 40-pin TFT Display for Raspberry pi DSI connector

Post by bfulda »

Hello all,

I was wondering if the 5.0" 40-pin TFT Display that Adafruit sells would work in the 40 pin DSI connector on the Raspberry Pi? I just got mine in an had this thought and before I fry something I wanted to ask if this would work or if anyone had any ideas about it. thanks

So here is another question:

Using the Mini Kit - 320x240 2.8" TFT+Touchscreen for Raspberry Pi and the 5.0" 40-pin TFT Display - 800x480 with Touchscreen,could you disconnect the 2.8" TFT and plug in the 5.0" one and expect it to work?

And, is all of the 40-pin display buses/connectors you guys have, the same? Rather are the pin-outs the same across the board? I'm not sure if there is a standard or anything, but if there is, do these products follow the same standard across your display products?

I just don't want to fry a board or system, so I'm asking for some help from you guys first. Thanks again!!

the 40 pin TFTs we have are NOT DSI at all, they are 'raw TTL' - furthermore, even if you did have a MIPI DSI display you cannot just connect a screen to the DSI port, there's a firmware blob that the RPi foundation has to release to make it work

the 40pin TFT's are totally incompatible with the SPI PiTFT - completely different chipsets. if you need a bigger screen, check out the 7" HDMI display we have in the shop

Whew!! Thanks for the info. That is exactly why I am asking the pros instead of just plugging stuff up.

I just noticed that the connections 'looked' similar and if someone from your shop was standing next to me, I would have asked. So thanks again for the info. Always appreciative of all that you guys do.

Last February, the Foundation announced Broadcom was open sourcing (under BSD) the VideoCore IV http://www.raspberrypi.org/a-birthday-p ... -broadcom/

They were offering a bounty of $10K for a demo of using the display on DSI. They apparently closed the bounty and no display has shown up.

What hurdles are there currently on a DSI display?
