Hi,
I'm working on a project where I communicate with a SPI device, my next step is to add screen to Raspberry Pi.
When I went over specification for PiTFT(resistive touch) (https://www.adafruit.com/products/1601) I notice that it uses both CE0 and CE1, which means that I can't use SPI for another device. But reading specification for PiTFT (capacitive touch) a saw that it uses ONLY CE0. Does this mean that I can freely use CE1 or is there a some sort of mistake?
thx in andvance

Re: PiTFT + SPI
The resistive TFT uses a separate SPI chip for the touch. The main driver chip handles the capacitive touch.
So, the capacitive touch screen does *not* use CE1

Thx!
Just to confirm - but it DOES use CE0?
