#TUTORIAL. GET STARTED WITH 3.5” LCD FOR RASPBERRY PI.

The 3.5 inch LCD Display is directly pluggable into a Raspberry Pi and perfectly fits various Pi models from B+ to Raspberry Pi 3B+. It is a brilliant alternative for an HDMI monitor. When set up, it behaves as a human-machine interface enabling the user to prototype with the Raspberry Pi device anywhere at any time.

 

 

Features:

  • 480x320 hardware resolution with 8:5 aspect ratio
  • Typical current consumption within 110-150 mA with a 5V supply
  • High-quality immersion gold plating
  • Resistive touch control
  • Simple installation procedure described below

 

 

Installation:

 

It is very easy to set up the display by installing an LCD driver on your Raspbian OS. It requires only 3 commands to be run on the terminal.

 

After setting up your Raspberry Pi, connect the LCD Screen to your RPi as shown below

 

 

 

Display works on SPI communication protocol so you have to enable SPI interface

 

Menu>Preferences>Raspberry Pi Configuration>Interfaces; click ‘Enabled’ for SPI

 

Or

 

type sudo raspi-config in the terminal, go to Interfacing Options, select SPI and enable it, click on Finish  to close the configuration menu

 

Restart your RPi to make sure that the configuration changes have been updated

 

Open the terminal by pressing Ctrl-Alt-T or by clicking on its icon located in the RPi taskbar at the top

 

Update your libraries, just for good practice

 

sudo apt-get update && sudo apt-get upgrade

 

Download the drivers from Github

 

git clone https://github.com/goodtft/LCD-show

 

Go inside the driver’s directory

 

cd LCD-show

 

List all the files in this folder to find the LCD35-show file (Just for good practice)

 

ls

 

Convert the file into an executable using super-user

 

sudo chmod 755 ./LCD-show

 

Run the executable

 

sudo ./LCD35-show

 

(if the command is not being executed, run  sudo chmod 755 ./LCD-hdmi)

 

RPi  will restart after running the program and your LCD will display the desktop

 

Switching back to HDMI Monitor:

 

If you want to switch back to an HDMI monitor from the LCD screen, the process is also very simple.

 

Every library also includes a file to revert back to HDMI

 

Go into the directory of the library

 

cd LCD-show

 

List all the files to find LCD-hdmi file

 

ls

 

Convert this file into an executable

 

sudo chmod 755 ./LCD-hdmi

 

Run the executable to view your Raspbian desktop from an HDMI monitor

 

sudo ./LCD35-hdmi

 

Like the previous time, Raspberry Pi will restart to switch to HDMI

 

 

 

We hope that this helps you, explore more and learn more.
