That project runs on 3.3v see schematics and pcb in attachment smiley
Another one

There is no information in datasheet that input are 5v tolerant (adafruit lcd board contains voltage level converter) so better asume that they need to be 3.3v logic level

I just received this LCD on PCB and I think that there is no voltage level conversion ! only 10k ohm resistor on SD card lines!
So I don't think that it's safe to connect this lcd to arduino directly !

Mmm hard to say I know that w5100 have problems with other devices on spi bus

Yes exactly

Just print the old text in white before printong new text smiley-wink works like charm

Hi
If You want to use hardware SPI use this definition (You can change those pins)
#define cs   10
#define dc   9
#define rst  8 
Adafruit_ST7735 tft = Adafruit_ST7735(cs, dc, rst);

LCD MISO goes to arduino MISO, MOSI to MOSI, SCK to SCK, CS to CS and there will be one signal left so connect it to any other pin. Like in Adafruit tutorial
10  Using Arduino / Displays / Re: Has anyone got these cheap LCD's to work with arduino? (ST7735R) on: January 12, 2013, 03:29:14 pm
my code is only for hardware spi (it is 2-4 times faster than software)
11  Using Arduino / Displays / Re: Has anyone got these cheap LCD's to work with arduino? (ST7735R) on: January 12, 2013, 04:57:27 am
There is a method to speed up communication
In Adafruit_ST7735.cpp search for
SPI.setClockDivider(SPI_CLOCK_DIV4);

and change it to
SPI.setClockDivider(SPI_CLOCK_DIV2);

That will speed up SPI bus

I was using it on 3.3v 8mhz atmega328p, not on 16mhz so it may not work

I think that SPI can be for touch controler not the LCD
13  Using Arduino / Displays / Re: Has anyone got these cheap LCD's to work with arduino? (ST7735R) on: December 26, 2012, 10:16:26 am
Yes smiley I tested already one without pcb (I made my own) and its doing fine smiley

Hi
I did smiley
They are superb smiley-grin The PCB layout is easy to design and make. Now you can get this lcd on ready pcb adapter for few bucks.
I already ordered 3 of them. Adafruit library works wery well smiley
i bought 2

so cheap as dirt smiley-grin

Hello
Can you show yours antennas ? smiley
