# Connect the display to the RaspberryPi
Here is some info on how to wire the display to the RaspberryPi.
## Full connection diagram (9 wires needed)
Wire the display connector according to the connector scheme below.\
**NOTE:** The 56 Ohm resistor is suggested for safety reasons - but it also seems to work fine wihtout it

SCK --------------------------- SCLK | GPIO 11 | PIN 23
SDI/MOSI ---------------------- MOSI | GPIO 10 | PIN 19
DC/RS ------------------------- | GPIO 24 | PIN 18
RESET ------------------------- VCC (soldered directly onto the display connector)

## Some explanation
|---------> Power
GND --|
VCC --|
|---------> SPI Interface (data transfer)
MISO -|
MOSI -|
SCK --|
CS ---|
|---------> Data/Command switch
DC/RS | (indicates whether the transfered data is a command or display data)
|---------> Power to the backgroud lighting
LED --|
|---------> Resets the display controller when pulled low
RESET |
# Configure the display
**TL;DR** just run ```make rpi-config```
