* The following GPIO use should be set in python RPi.GPIO, by GPIO.BCM, image refer to here.

|-
| 12 || GPIO18  || RPI_1 || D3

|-
| 7 || GPIO4  || RPI_7 || D9
|}
* Also can referring to following image. 7-GPIO4/RPI_7 means: for GPIO.BOARD number is 7, for GPIO.BCM number is 4, and for our GPIO shield number is 7

== Using with 5110 LCD by wiring PI==
* Make sure you have [http://wiringpi.com wiringPi] installed.
* Navigate to the demo code folder, open the make file you will see the following content:
* Compile code by wiringPi:
 gcc -g -o lcd5110 PCD8544.c pcd8544_rpi.c -lwiringPi
* run make command and then run ./lcd5110 as an executable file.
