How to use 2 GPIO displays on one Pi Zero?

Tue May 10, 2016 1:58 am

I'm working on a a project like the hololens and i need to be able to have 2 displays hook up to the same Raspberry Pi Zero. The displays will both be a 2.2 inch 18-bit color TFT LCD display with MicroSD card breakout from Adafruit (I am also wondering where i can get the driver for this device). If you can help, that would be wonderful! :D

Do you mean this screen?

The one that has an adafruit tutorial for it?

Also mentioned is that there might be linux framebuffer support for it.

and someone has used that to write a simple tutorial

The refresh rate on these SPI screens isn't great and connecting two screens probably won't give you the result you are looking for.

any other screens of this size or a little smaller that are better? If so, how could I use two displays of that kind?
