Wiring up the display in SPI mode is pretty easy as there are not that many pins! We'll be using hardware SPI, but you

can also use software SPI (any pins) later. Start by connecting the power pins

3-5V Vin connects to the microcontroller 5V pin

GND connects to Arduino ground

SCK connects to SPI clock. On Arduino Uno/Duemilanove/328-based, thats Digital 13. On Mega, its Digital 52

and on other chips its ICSP-3 (See SPI Connections for more details (https://adafru.it/d5h))

MISO is not connected

MOSI connects to SPI MOSI. On Arduino Uno/Duemilanove/328-based, thats Digital 11. On Mega, its Digital 51

and on other chips its ICSP-4 (See SPI Connections for more details (https://adafru.it/d5h))

CS connects to our SPI Chip Select pin. We'll be using Digital 10 but you can later change this to any pin

RST connects to our Display Reset pin. We'll be using Digital 9 but you can later change this pin too.

D/C connects to our SPI data/command select pin. We'll be using Digital 8 but you can later change this pin too.

For the level shifter, we use the CD74HC4050 (https://adafru.it/CgA) which has a typical propagation delay of ~10ns
