ILI9341 TFT SPI touch

Hello,

I am trying to interface with a ILI9341 based touch screen modules.
However, I am pin limited on my project on the Arduino side of things.

It seems that both the LCD AND the Touch modules are using SPI based communication.
Is it possible for me to connect both of them to the SPI port of my arduino board, saving 3 pins and allowing me to use HW assist SPI (instead of one HW and on SW)?

What would be the drawbacks?

Thanks,
Cyrille

Yes, you can put ILI9341, XPT2046, SD card all on the same 3.3V SPI bus.

Very straightforward with 3.3V Zero, Due, STM32, ...
You need level shifters on every logic signal for a 5V Uno, Mega2560

Hello,

Thanks!
Will try.
