Hello to all... I have problems to get the nextion running... I spend days of trys but i cant get it to worlk.. In the internet there are some manuals but the most dont work or i dont check it how to do. So i decidet to maken an pdf MANUAL for beginners to install Nanodlp and Nextion on an brand new RPI3B+ But at moment my display shows only Connecting to printer...
What i did until now :
Download the new Nano DLP RPI Image from
https://www.nanodlp.com/download/
If you use Windows download ETCHER from https://www.chip.de/downloads/Etcher-Image-to-USB-SD-Karte_96464610.html and install it.
Unzip nanodlp and start ETCHER Select Image you want to flash on your SD Card Select nanodlp and flash it
Download Putty from https://www.putty.org/
Connect your RPI 3B+ with an ethernet cable to your router After flashing sd put SD Card into the RPI 3B+ and start RPI
Go to your router interface ( in my case 10.0.0.138 ) and login Watch in your Router Interface and look for RPI 3B+ ip-adress
Open Putty on PC and type in ip-adress from your RPI 3B+ and click open Then you come to the putty interface box and you can login to your RPI 3B+
Login as: pi pi@10.0.0.5´s password: raspberry
Now youre on the RPI 3B+ Type sudo raspi-config and make some settings in the “Raspberry PI Software configuration tool” The Changes debends on your system or on the country you live
Got to 4. Localisation Options and change Change Locale to “de_DE.UTF-8” (ONLY IN MY CASE) Change Timezone to “EUROPE” and then “BERLIN” Change Keyboard layout
If all settings changed got to finisch and click enter
Now you see the black putty interface again. Now update the RPI3 B+ and type sudo apt-get update sudo apt-get upgrade sudo reboot
Congrats so your RPI3 B+ is in ground configuration !!!
Now Type the Ip-Adress from your RPI 3B+ into your webbrowser
Now you can log in to your NanoDLP interface on RPI 3B+
Here you can chose different types of preconfigured Printers. In my case I use the “mUVe3D” Version. Click on it and RPI 3B+ restarts
After Restart look if there is an “New Version Available” in the right upper corner. If yes click on it and “Upgrade to the latest stable version”
Now the RPI 3B+ update and reboot again
GET NEXTION TOUCH DISPLAY WORK ?!?!?! ( Here I need Help !!! )
Go to https://github.com/Tibus/TouchScreen-For-NanoDLP/tree/master/nextion/tft And download the tft file for your display. (in my case the Nextion 3,2)
Put the tft file into an emty MICRO SD Card Put the card into the cardslot on your Nextion Power on the nextion and it will update automaticly If ready the display shows 100% success
Now get back on Putty and log in to your RPI 3B+ and check your serial0/serial1 connection
Type followed lines cd /dev ls- l
Now you have to scroll up and see followed picture Serail1 -> ttyAMA0
Type Sudo raspi-config Go to 5 Interface Options
First question: Would you like a login shell to be accessible over serial NO Second Question: Would you like the serial port hardware to be enabled YES
The prompt will read : The serial login shell is disable The serial interface is enabled
Select ok and allow the RPI3B+ to reboot
Type sudo nano /boot/config.txt add fllowed line to the config.txt dtoverlay=pi3-disable-bt exit and save changes
sudo reboot
After reboot you log in over putty again and type cd /dev ls -l
Now it should show follow lines under serial
Serial0 -> ttyAMA0 Serial1 -> ttyS0
Download Nextion Screen Software for Simple installation
Type sudo mkdir /home/pi/nextion;(wget https://github.com/Tibus/TouchScreen-ForNanoDLP/releases/download/V0.2/pi2_3.tar.gz --no-check-certificate -O - | sudo tar -C /home/pi/nextion - xz);cd /home/pi/nextion; sudo ./setup.sh
NOW MY config.txt SHOWS
Enable audio (loads snd_bcm2835)
dtparam=audio=on disable_camera_led=1 hdmi_pixel_encoding=2 start_x=1 gpu_mem=128 enable_uart=1 dtoverlay=pi3-disable-bt
MYcmdline.txt SHOWS
dwc_otg.lpm_enable=0 console=tty1 root=PARTUUID=b94f2c65-02 rootfstype=ext4 elevator=deadline fsck.repair=yes rootwait
BUT MY DISPLAY ALWAYS SHOWS CONNECTING TO PRINTER….
What is wrong ?? What changes I must make to get it work ???
