Is it possible to turn backlight off on 7" 1024 display ?

I am using Raspbian version:2017-03-02 but didn't execute the command below after installing the LCD 3.5
driver; after reboot of pi which happened after driver installation, my pi is hung on Kernel panic - not syncing: VFS unable to mount root fs on unknown -block[179.2]..

Any ideas, how to get out of hung screen ... and then run commands below.?

cd LCD-show
sudo dpkg -i -B xserver-xorg-input-evdev_1%3a2.10.3-1_armhf.deb
sudo cp -rf /usr/share/X11/xorg.conf.d/10-evdev.conf /usr/share/X11/xorg.conf.d/45-evdev.conf
sudo reboot

Bonjour,
Je n'arrive pas à calibrer mon écran
cd /boot
cd LCD-show
sudo dpkg -i -B xinput-calibrator_0.7.5-1_armhf.deb
DISPLAY=0:0 xinput_calibrator

Une fenêtre s'ouvre avec les croix rouges mais j'ai beau cliquer, sur les croix rouges, avec le stylet, rien ne se passe.

Merci pour votre aide

So here is the setup:

I downloaded the ARM image RaspberryPI Foundation from:
https://www.offensive-security.com/kali-linux-arm-images/

Then I proceed to mount the image to a SD card and boot the system.

On HDMI on my tv I then tried to install the LCD 5" driver following these steps:
git clone https://github.com/goodtft/LCD-show.git
chmod -R 755 LCD-show
cd LCD-show/
sudo ./LCD5-show
As shown in the PDF that came with the CD for the Driver installation.(attached)

The system rebooted and the screen adjusted.
The actual LCD 5" HDMI display works just fine!

BUT, the system rebooted in text mode and I cant get it to work in graphical mode again.

I tried so far:

startx
This presented me with an error saying that
(EE) Server terminated with error (1). Closing log file.log" for additional information.
(I can't find the log file for additional info, I don't know where it is)

apt-get update
apt-get upgrade -y
apt-get install -f gdm3
gdm3
This did not work, the terminal was unresponsive after.

Do you guys have any idea what could possibly be going wrong?

How to install the LCD driver (En).pdf

So I calibrated my 3.5inch GPIO touch display (LCD35-show) and copied the result to /etc/X11/xorg.conf.d/99-calibration.conf
but as I restart nothing seems to happen.
Everything is still the same. The touch is inverted and x and y are also inverted.
I tried hardcoding the /boot/config.txt by putting this code for the overlay:
dtoverlay=tft35a:swapxy=1:xmin=22255:xmax=22255:ymin=49202:ymax=49612:yinvert=1:xinvert=1
Still no result ...
Any suggestions?

Can I use your script to make this work?

i have followed the EXACT CORRECT steps but when it reboots it still displays as white....

Hi,

I am using waveshare 2.8 inch LCD with PI3. I followed the procedure given in the link below.

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

When I tried to run the sudo ./LCD28-show command, my PI got restarted. Everytime I run this command, PI gets restarted. Any ideas?

I am using Raspbian (Jessie-Lite).

Thanks

Hi, we have the last raspbian version from march 2017 and a 3'5 LCD touchscreen.
The initialisation worked very well, but, we are not able now to return to the hdmi screen.

We tried the : sudo ./LCD-hdmi
But the answer is : "sudo ./LCD-hdmi : command not found"

If we unplug the LCD the raspberry stops booting in the middle...
You think, we miss something??

Attempting to use your repository to get a Kuman 3.5" touchscreen to work on a Pi3.

Downloaded git and cloned your repository with no issues, but "chmod -R 755 LCD-show" command doesn't do anything. Any ideas?

I tried to get the display running with your script and several guides I found on the Internet without any changes.

I am using ArchArm and Raspbian - both without success!

Could the display be broken?

Hi,

First off I want to thank you for your script. It work really well with the xpt2046 3.5" touch screen on Raspbian Stretch.

I have two identical touch screens, but on one one of them I'm getting colour corruption when the mouse moves around, especially over the background image.

I was wondering if this could be due to a bad GPIO connection or the speed the data is being sent to the screen through the GPIO is too high? Is there a way to slow down the GPIO speed?

Thanks

Neil

I have a 3.5" GPIO display, and after following the instructions, I get nothing but a black screen with a flashing underscore. The display is partially working, as I can press CTRL+ALT+F1 and see the terminal for just a moment, but it simply flashes on the screen and disappears.

is it planned to support pi zero ?

Hi
I've tried editing /boot/cmdline.txt and /bott/config.txt but neither are affecting a screen rotation of the GPIO 3.5" LCD screen with touch. The HDMI output does rotate but I want the LCD to rotate the same way.

How can I make this work as I'm very out of my depth on this.

Thanks
Dean

I have followed your installation guide using Raspbian-2017-03-02 on an Pi3b with LCD7C 1024x768 screen.

Both devices are powered from a single 5V 2.5amp power supply, the screen piggybacking power off the Pi via USB

I am able to get the screen up and running but without any Touchscreen functionality.

Anyone have an success trying to get touchscreen functions working with this screen?

The cp -r option means recursive down a directory tree. However, ./usr/99-calibration.conf-35 and ./usr/99-fbturbo.conf are being copied as individual simple files. At minimum, this is confusing. This may be okay now but it might bite you in the future when someone does maintenance.

The other bash scripts have similar issues.

Could you please provide a setup to rotate the screen and mouse?

Thanks

5inch_HDMI_raspbian jessie with pixel_2016-11-25.7z
after i installed raspbian image from above package ! my have rainbow screen!
have anyone solved it! it happened in both pi2 and pi3

New to github so im a noob it asks me to login after the git clone command what is the login

edit: Figured it out typed command wrong

Hi and thank you for your efforts.
Unfortunately WaveShare does not have any driver for Touch on PI 3.
I have Raspbian Jessie 2017-07-05 (Latest Edition), But I could not run Touch for my LCD.
I have followed your instructions, but the problem is still remained. I have emailed to WaveShare support as my LCD is from WaveShare, but they did not answer me, yet.

Do you have any idea?

Best regards,
Hasan

There is a 1 cm border around the edge of the touchscreen that cursor will not pass, and is unaccessible for touch. With a keyboard and mouse I am able to move the cursor around the entire screen. The cursor will not move into this area with touch.

Hi,

I have got the 5 Inch Display to work with changing HDMI Parameters in my fex config:

[disp_init]
disp_init_enable = 1
disp_mode = 0
screen0_output_type = 3
screen0_output_mode = 5
screen1_output_type = 3
screen1_output_mode = 5
fb0_format = 0
fb0_width = 800
fb0_height = 480
fb1_format = 800
fb1_width = 480
fb1_height = 0
hdcp_enable = 1
hdmi_cts_compatibility = 0

[hdmi_para]
hdmi_used = 1
hdmi_power = "vcc-hdmi-18"
hdmi_x = 800
hdmi_y = 480
hdcp_enable = 0
hdmi_cts_compatibility = 1

However I cannot get the touch screen to work.
The Software that came with the screen is only for Raspberry, but I want it to work with Orange PI.

Is there any hints how to get it running with GPIO or USB? Both methods do not work at the moment.
I am using latest ARMBIAN on my Orange PI.

Hi,

I am using RTIMULib with PI 3 for MPU9250 but unable to read anything. When I run the below code, it says 'No IMU found'.

RTIMUSettings *settings = new RTIMUSettings("RTIMULib");

    RTIMU *imu = RTIMU::createIMU(settings);

    if (imu == NULL || (imu->IMUType() == RTIMU_TYPE_NULL)) {
        printf("No IMU found\n");
        exit(1);
    }

I used i2cdetect -y 1 command to see if IMU is detected and I received 0x68 address.

Any ideas what I am doing wrong?

Thanks

Hello,

After connecting the screen and flashing 3.5inch-raspbian jessie with pixel_2017-03-02.img and starting minecraft-pi, I get a black screen. Have you tried that? Is this supposed to work?

thank you

So I got the 3.5" Full HD 3561. Is it covered yet? It uses HDMI and SPI for touch screen. I did not find any drivers yet.

Hello, i have a Orange PI Zero. But I don't think so is rıun with my display. Can It run display? Thank you very much.

Hi, this is not bugreport, but succesreport ;-)

Recently i bought the 3,5" HDMI LCD, marked with 2017/2/1 version, i read some driver installation instructions, i download driver LCD_show_35hdmi.tar.gz from http://en.kedei.net/ and inspect it little. In install script i found, that it install (copies) a lot of binary files for some older kernel. As longtime Debian user i decided to try it with current Raspberry Pi kernel, without any files installed/copied into /usr directory. After search on internet i found your repository and i see that it can be reasonable solution (thanks for infos). To be sure, i start with fresh full raspbian jessie image (2017-04-10), where i did only two changes - i enabled ssh and configured network.

Settings

Display

Display works out of box, after i plug it and power the RasPi i can see GUI, but it uses too high resolution (i didn't inspect exact value). Then i took HDMI settings from driver's config.txt and placed into /boot/config.txt:

hdmi_group=2
hdmi_mode=87
hdmi_cvt=480 320 60 6 0 0 0
hdmi_drive=2

After reboot, the display show nice 480x320 screen.

Touchscreen

This was a big problem for me, because i did not encounter with touchscreens before and therefore i had zero experiences with. But after many try-error attempts i was finally success.

I start with enabling touchscreen overlay. First i start from driver's config, then i tried your config and finally i have in /boot/config.txt:

dtparam=spi=on
dtoverlay=ads7846,cs=0,penirq=25,penirq_pull=2,speed=10000,keep_vref_on=0,swapxy=1,pmax=255,xohms=150,xmin=199,xmax=3900,ymin=199,ymax=3900

After reboot the touchscreen work, but the X/Y axis are flipped and setting swapxy has no effect. Then i noticed xserver-xorg-input-evdev package in your repo, then i uninstall
the xserver-xorg-input-all and xserver-xorg-input-libinput and install from official repo the xserver-xorg-input-evdev:

aptitude purge xserver-xorg-input-all xserver-xorg-input-libinput
aptitude install xserver-xorg-input-evdev

I tried to copy /usr/share/X11/xorg.conf.d/10-evdev.conf as you suggests, but it has no effect for me, then i revert it back this file. but i leave these packages (un)installed.

Then i install xinput-calibrator from official repo (BTW version 0.7.5+git20140201-1):

aptitude install xinput-calibrator

Then i add 99-calibration.conf from your repo into /etc/X11/xorg.conf.d/. After xserver restart the touchscreen works better, the axis was not flipped, but was inverted now. Then i add into 99-calibration.conf:

Option "InvertX" "1"
Option "InvertY" "1"

After xserver restart, the touschscreen starts to work and i was able to run (via ssh, i have no keyboard connected into Raspi):

DISPLAY=:0 xinput_calibrator

After finishing calibration it provides setting for me:

Section "InputClass"
    Identifier      "calibration"
    MatchProduct    "ADS7846 Touchscreen"
    Option          "Calibration"   "188 3928 3895 117"
    Option          "SwapAxes"      "1"
EndSection

I replaced content of 99-calibration.conf by these settings, restart xserver and touchscreen works as expected.

Audio

I didn't try yet.

Conclusion

Although i am not sure about xserver-xorg-input-evdev/xserver-xorg-input-libinput step,
the HDMI display with SPI touchscreen works with no software outside official repositories and with these steps:

1. optionally tweak HDMI settings in /boot/config.txt
2. add touchscreen overlay settings in /boot/config.txt
3. uninstall xserver-xorg-input-all and xserver-xorg-input-libinput
4. install xserver-xorg-input-evdev
5. copy usr/99-calibration.conf-35 (this repo) into /etc/X11/xorg.conf.d/99-calibration.conf
6. tweak 99-calibration.conf manualy or with xinput_calibrator
7. be happy

I needed to pull off the case. I was removing it quite gently with a spudger (aka black tip) when that piece of the case cracked. I have never seen such a brittle piece of plastic!

Please create an area where the contents of the DEB files and the scripts which build them are available for browsing. Thank you.

Anyone gotten this to work on Raspbian Jessie Lite (2017-04-10)? I'd like my pi 3b with the 3.5 LCD to just act as a kiosk (run browser on boot).

Was hoping I could just do the following but have not had luck:

sudo raspi-config
#boot options > cli no login
sudo apt-get install -y git xserver-xorg-video-fbturbo openbox midori unclutter xinit
echo "exec openbox-session" > ~/.xinitrc
mkdir -p ~/.config/openbox && cp /etc/xdg/openbox/* ~/.config/openbox

echo "midori -e Fullscreen -a http://www.espn.com" > ~/.config/openbox/autostart

nano ~/.bashrc
#at the bottom put

if [ $(tty) == /dev/tty1 ]; then
   startx -- -nocursor
fi

I have 5 inch LCD and graphics works fine. Touchscreen also works but it doesn't work on right and left sides and calibration is off. I kept calibrating several times and it doesn't work.
This is using raspbian jessie, latest image.

The refresh rate on my pi 3b running Raspbian GNU/Linux 8 (jessie) seems to be pretty low/slow.

How can I increase the refresh rate so I get higher FPS?

My /boot/config.txt has:

...
dtparam=audio=on
dtoverlay=ads7846,cs=1,penirq=17,penirq_pull=2,speed=1000000,keep_vref_on=1,swapxy=1,pmax=255$
dtoverlay=tft35a:rotate=90

I have tried increasing gpu_mem, it does not have any impact.

I followed the exact instructions on the main page and it crashed my device. I now get:

End kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,6)

I have 800x400 screen. But in Kali Linux I havent got it. Its only 600x800

to this screen there are instructions:

git clone https://github.com/goodtft/LCD-show.git
chmod -R 755 LCD-show
cd LCD-show/
./LCD7B-show

I can't run more GUI.

Give advice on how to be and what to do

Hello,
is current driver (touch and hdmi) works with BBB ?
thanks

Is there a way to make this driver work on android? i installed emteria https://forum.emteria.com/ android and i have a waveshare 10.1 inch screen but the driver exec doesnt work ... any suggestions ?

Referring to the LCD-35-show data, I don't understand what the version differentiation is good for. Can someone please explain?
I have the feeling this is focused on the wheezy release and became deprecated as soon as a new major release (jessie, stretch) came out.
This seems fairly important. In my cases, sometimes the evdev program was not installed due to the version nr.

have a purple vertical bar of 2-3 pixels on the left side

Just bought the screen, and found this out.

I got it to work following the instructions that came with it, but only if it's with a fresh install of 2017-04-10-raspbian-jessie.img

As soon as you run "sudo apt-get update" and "sudo apt-get dist-upgrade" the screen just stays white.

It also ends up killing the Raspbian image as well.

I'm looking for a screen for my Pi, but one where the drivers break simply from performing OS updates is not user, or customer friendly.

Hi,
Is it possible to turn off backlight on power dpms off event on a LCD
3.5? Or is it directly fed by +5v pin?

when i follow these steps and reboot ! but the screen only show white screen!!

Hey there, first thing first, THANK YOU so much. I just bought a 3.5 inch display for my RPi 2 B+ model, and was searching from continuously 18 hours for the supportive Drivers for the same, then got your GitHub Link, which helped me alot. Thank You again.

But, I mainly need it to work on KALI LINUX (ARM version). On which, this driver is not working. Can you please provide me the Driver for other Distro too (mainly for KALI )? or I would be glad if you can help me with the same in other way, like the dependencies it requires, repositories, tolls, etc. Thank you once again. Looking forward for your reply.

i would like to rotate my 7" lcd screen i did it
but i have a probeleme with touch screen
can i find a solution ?

After I followed the instruction and installed the driver, it automatically reboot but then it
never boot up

. I'm using the 3.5" TFT display and my raspbian is the latest version August 2017.

Previously I was able to run

sudo ./LCD35-show 180

Doesn't seem to be working with the latest. Is there a different way to rotate the screen?

pi 3 crashed after i installed the 7" goodtft display driver , pi3 is working on tv but when install driver for 7" display it s dead , any solution up to now ?

Im using a 3.5in touch screen and all it displays is the boot sequence then the display turns black any help is appreciated thanks

Hello.

I have problem with installation my display.
Yeasterday I have made install without problem, but I messed something on my Pi3, so I decided to make clean install.
Download jessie image, write to card, boot and make system resize and other things.
After that I have downloaded repo, made chmod and went into directory with files.
Now excecute sudo ./LCD32-show command, Pi shutdown, but after reboot, it hangs up in boot process on "systemd[1]: Starting Create Static Device Nodes in /dev...

Display is only white and Pi is doing nothing.

Thx for advice.

Mickey

I done this both online and offline and every time I use the last command
sudo ./LCD5-show my pi 3 restarts and then hits an error and gets stuck there. The error is "Kernel Panic : VFS :Unable to mount root fs on unknown-block". I cannot for the life of me get it working.
