Drive 16×2 LCD with Raspberry Pi

Objective:
In this project, we will use GPIO pins to send text to 1602 LCD screen.

If you don’t know what is GPIO layout, check our tutorial How to read Raspberry Pi i/o pin diagram (GPIO pin graph)

Parts:

1 pc Raspberry Pi 2/3/zero raspi
1 pc 8GB MicroSD memory card preinstalled Raspbian OS. 8gtf
1 pc 1602 LCD screen 1602LCD
1 pc Potentiometer Potentiometer
1 pc breadboard BREADBOARD
1 pc GPIO breakout kit(optional) breakout

Prerequisite:

Raspbian should be upgraded to latest version in order to support RPI.GPIO module
Please run following commands in shell:

  • sudo apt-get update
  • sudo apt-get upgrade

Raspberry Pi and 1602 LCD pin connection

LCD Pin Description Pi Function RasPi Pin
01 GND GND 06
02 +5V +5V 02
03 Contrast To Potentiometer middle pin
04 RS GPIO7 26
05 RW GND 06
06 Enable GPIO8 24
11 D4 GPIO25 22
12 D5 GPIO24 18
13 D6 GPIO23 16
14 D7 GPIO18 12
15 +5V +5V 02
16 GND GND 06

Circuit Graph:

Caution: Unlike Arduino board 5V input voltage, Raspberry GPIO pin accept only 3 Volt. Wrong voltage input might damage the Pi board. Please be very careful!

Write python code
You have two ways to write python code:
Option 1)
download http://osoyoo.com/driver/pi_lcd.py and copy/paste it to raspberry pi

Option 2)
You can also download above python file from our server by typing following shell command:

sudo wget –no-check-certificate http://osoyoo.com/driver/pi_lcd.py

Finally, run following command in shell window:

sudo python pi_lcd.py

Adjust the Potentiometer to make LCD text displaying clearly. You will see following text string rolling in LCD screen:
LCD work with
Raspberry Pi!

What’s Inside?
1x 5 inches DSI Touch LCD Screen for Raspberry Pi
1x DSI Ribbon Cable
1x Philips screwdriver
1x User manual

Feature
The 5″ LCD display is an LCD display which connects to the Raspberry Pi through the DSI connector.
It is capacitive touch LCD screen.
It is compatible with Raspberry Pi 3B+, 3B, and 2B.
Equipped with reserved fixing holes for control boards – suitable for Raspberry Pi 3 model B+,3 model B, and 2 model B.
It doesn’t need install driver, and you can plug and play.
The Physical resolution of LCD display is 800*480.
No need additional power.

Creative for DIY

As OSOYOO 5″ DSI touch screen connect with Raspberry Pi via DSI ribbon cable, makers can extend the raspberry pi GPIOs for DIY projects.

What’s more, no need driver and supported multiple Linux operation systems, makers can create more ideas.
