Thanks again.
I've just connected the display to a uno through a logic level converter and with display powered from 5V. Hardware spi works.
Using 3.3V DOESN'T work...probably the display regulator dropout volts.
I reconnected the pic running at 5V connected to display through a logic level converter and again hardware spi didn't work.
edit on the uno hardware spi is visibly faster than software.

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Lower the operating voltage....
But, HWSPI and SWSPI works.
Thanks again.

The original mega 328 ILI9341 GLCD with the XPT2046 doesn't display anything if I comment #define ILI9341_HardwareSPI
I dont you can mix and match the older .h with the XPT library.
oops. forgot #define XPT2046_HardwareSPI. if I comment that as well it works...touch still not working with new display. I send as your email if ok
No problem. You know what to do :-)
