Can I connect this screen to Pi GPIO?

[Gorse212]

I happened across one of these screens: https://learn.adafruit.com/adafruit-3-5 ... /downloads which is primarily meant for use with Arduino. It has SPI and a "bidirectional 8-bit 8080 type parallel interface". I want to try and use it in my handheld gaming project, therefore I would rather not use SPI due to the bad frame rate.

Looking through the data-sheet, the controller supports the DPI interface, however the pinout for doesn't seem to match what would be required for 8 bit DPI. I'm pretty out of my depth here and have spent a few hours trying to figure out if its possible to use this with a raspberryPi using GPIO, so if anyone could help me that would be great.

My plan B is to use SPI and see if I can install the drivers to increase frame rate.

Hi,

Yes you can use this Lcd, but SPI is for Sdcard access and touchpanel,
I don't know the frequency of GPIO but not so far under OS
( unlike use alternative function of GPIO with DMA )

You might be able to connect and drive it from the Pi but not with DPI interfave; looking at the schematics shows only 8bits for color connected (out of 18 in total) and no connection to the RGB block (Hsync/Vsync/DE/clock)
look for a different display

My plan B is to use SPI and see if I can install the drivers to increase frame rate.

That would be my recommendation. It will be far easier to use a display designed for use with a Pi than try and use something which isn't if you don't have the prerequisite experience.

You may find that SPI performance is good enough, don't need faster framerates and special drivers.
