Has anyone got these cheap LCD's to work with arduino? (ST7735R)

Using Arduino Displays
19

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
