Nextion Touch Screen for nanodlp

sudo · 2019-05-03 12:30:58

Hello,

I tried everything that I found on Github and on this forum, but I couldn't get anything displayed except "Connecting to printer..." message.
I used the Nextion NX4832T035 which is 3.5 inch and .tft found on the github of Tibus
I have installed NanoDLP on the Rpi 3B+. And I use PUTTY to use the Terminal of the Rpi.
I followed all solutions(tutorial) posted on this forum and none of them works. I have even tried mixing these solutions.
Can anyone give me an updated solution or tutorial to make the touch screen work ?

Thx,
sudo

Have you tried internal nextion support?

Hello,

I haven't tried the internal nextion support.
As my touch screen displays "Connecting to printer...", I think it works well. So I think the problem is the configuration of Nextion for NanoDLP.
And I don't think the Nextion support will give me the steps to do this. It's why I posted here.

To use internal support you have to do two things:
1. Correctly state serial address of nextion on nanodlp setup page
2. Load official TFT file to nextion

Hello,
I can't state the serial address of nextion on nanodlp setup page. As you can see on the screenshoot I don't have this parameter:

Did I connected the Nextion screen with the right GPIO ?

PS:
And I dont' know why, sometimes when I press the Nextion sreen the NanoDLP interface appears but the button doesn't work

Have you enabled serial port on rpi?

Now use Putty https://www.putty.org/ and connect with ssh to IP address from the Raspberry PI.
Login with user: pi and password
Then do: sudo raspi-config
Go to:
Interfacing Option->Serial
choose Enable serial console as NO
choose Enable serial hardware as YES
do not reboot the pi3
then do next commando’s
sudo apt-get update
sudo apt-get upgrade
sudo reboot
After reboot see web page if up and running, go back to putty connect and login.
Do: sudo nano /boot/config.txt
add the following lines:
dtoverlay=pi3-miniuart-bt
force_turbo=1
Save the file.
sudo nano /boot/cmdline.txt
you will see something like:
dwc_otg.lpm_enable=0 console=serial0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline fsck.repair=yes root wait
remove the line: console=serial0,115200 and save and reboot for changes to take effect.

This is tested with Beta version 2163

Where have you find this TFT file ???

Yianni-VJ · 2019-05-09 07:01:15

johanvd,

In your instructions, you write "dtoverlay=pi3-miniuart-bt"
nanoDLP support page writes "Add following line: dtoverlay=pi3-disable-bt"

@ vladfr: "Where have you find this TFT file ???"

-> The original TFT files (.. and also the corresponding HMI files..) can be downloaded at Github:
https://github.com/Tibus/TouchScreen-For-NanoDLP

Alternatively, you can create your own touchscreen with the nextion editor:
https://nextion.itead.cc/resources/down … on-editor/

As i was not 100% happy with the touchscreen layout of the original GitHub files, so i modified them with the NextIon editor to fit my needs..
I have used the HMI files (Input file for editor) from the GitHub Nextion repository as a basis for the touchscreen of my printer.
When compiling the HMI files in the NextIon editor, you get the compiled TFT file (output file from editor) that then can be uploaded to the Nextion.

.. If you are not happy with the current layout/design of the TFT files available on GitHub, you should try the Nextion editor; it is very easy making modifications to the existing HMIs or even create a new HMI..

cheers :-)

Official TFT files exist on nanodlp/download page.

@Shahin, thk for this information. I decide to change my nextion screen for the 3.2 enhanced and now it's good for the screnn... But when i touch the screen nothing append Do you have an idea ?

vladfr · 2019-05-29 07:45:19

Hi,
all my problems have been solved. I forgot to assign the right port address.

Thk for all !!

Bixx · 2019-05-29 21:10:53

@vladfr, can you explain which port setting you changed and what you changed it to?

TIA

ackta79 · 2019-06-05 18:03:04

@lord0815 did you have installed Tibus for nextion on the last nano ver (2227)
If yes can you explain me how?
Big thanks
