I have a 3.5-inch display(MPI3501)(ILI9486 based) and a Raspberry Pi 3A+.

The Datasheet-


Here are the specifications.

The library link-


The LCD world link-


It interfaces over SPI and plugs into the first 26 pins.

The display runs off power from the GPIO.

I'm running Raspbian.

The display has a 26 pin connector for easy attachment.

I get no error messages whatsoever.

I tried LCD-world's libraries.

The scripts run and the pi reboots, but the output looked white and blank like this-

I ran the following commands

sudo rm -rf LCD-show
git clone https://github.com/goodtft/LCD-show.git
chmod -R 755 LCD-show
cd LCD-show/
sudo ./LCD35-show

this is what LCD35 looks like-


sudo ./system_backup.sh

sudo rm -rf /etc/X11/xorg.conf.d/40-libinput.conf

sudo sync
sudo sync
sleep 1
if [ $# -eq 1 ]; then
sudo ./rotate.sh $1
elif [ $# -gt 1 ]; then
echo "Too many parameters"

echo "reboot now"
sudo reboot

I tried changing the power source but it was the same. I checked the compatibility for the display. It supports a 3A+. The Pi restarts. I am interfacing over Vnc and ssh cuz the HDMI is disabled during the use of the SPI display.

I ran a command to check the version

uname -v


#1333 SMP Mon Aug 10 16:45:19 BST 2020


uname -r




lsb_release -a


Distributor ID: Raspbian
Description:    Raspbian GNU/Linux 10 (buster)
Release:        10
Codename:       buster


Also, tell me if you know any other 3.5-inch display libraries with touch support. Thanks!

    This is the third time you have asked the same (or similar) questions. You have FAILED to provide the most basic information i.e. the SPECIFICATIONS of the screen. – Milliways Oct 12 at 7:32
  • I have flagged this question as duplicate. And a advice, if you want help, SHOW SOME RESPECT !!!! – Mats Karlsson Oct 12 at 7:47
  • And stop posting a bunch of pictures, post specification and references (URL) instead! – Mats Karlsson Oct 12 at 7:48
  • @MatsKarlsson I am deeply sorry. I realise I should read more questions before posting mine. here are the specifications. the library link github.com/goodtft/LCD-show the link LCD world link lcdwiki.com/3.5inch_RPi_Display – Isaiah Paul Oct 12 at 9:12
  • i'll add more to the question in a bit give me 20 min – Isaiah Paul Oct 12 at 10:13

Please read:

  1. https://raspberrypi.stackexchange.com/help/how-to-ask

  2. The comments from the previous post, they have incredibly good advice! They are quoted below for your convenience.

First thing is to describe the actual hardware you have - what screen, how it's connected, where it was from and version of the OS you are using. So far there are more versions of screen than I have Pi boards handy... without this basic info no one will know where to start to help you. Also general statements like tried multiple times with changing stuff I knew but I failed does not say what you did and if you saw any messages... It's worth sitting down and thinking about your problem from our point - we cannot see what you can or know what you have done. – Andyroo Oct 8

@IsaiahPaul sit down in front of your Raspberry Pi ... look at it very carefully and describe to a blind person what you see ... put that description into your post – jsotola Oct 9
