hello i bought https://www.aliexpress.com/item/NanoDLP … 4c4dGQ8PdD
i got this TFT from https://github.com/Tibus/TouchScreen-For-NanoDLP and i modified the HMI to fix my screen 5 inch base not advance
after trying Nano DLP TFT its not working same error stuck at connecting to .....
and i want to change the rxd and txd GPIO numbers because that shield use TXD number 15 and RxD pin number 16
and i check nanodlp files it says
txd1_pin GPIO pin for TXD1 (14, 32 or 40 - default 14)
rxd1_pin GPIO pin for RXD1 (15, 33 or 41 - default 15)
so both TFT stuck at connecting to printer , is the shield is broken ? or system error ? i am using pi 3 b + and os ( Simple Installating on Raspberry Pi ) which is ( NanoDLP SD card image file )

maybe i dont need to edit the GPIO , then what should i do ?

NanoDLP internally support nextion displays you do not need external software. Try it and let me know if it cause any issue.

https://www.nanodlp.com/download/#nextion i pick the correct model and upload on sd and flash it , still not working , so what should i do

updating ****
after using that code
mkdir /home/pi/nextion;(wget https://github.com/Tibus/TouchScreen-Fo … 2_3.tar.gz --no-check-certificate -O - | tar -C /home/pi/nextion -xz);cd /home/pi/nextion; sudo ./setup.sh
now it pass the connecting , but when i press on any thing like plates , projector nothing happen and i am using port /dev/ttyAMA0
i did try another tft other than nanodlp the same , when i press on settings or plates nothing happen at all
so what should i do now

updating*****
i decided to try the nanodlp image , the simple way of installation
i used nanodlp TFT files 5 inch basic , still not working , it stuck at connectiong , so i decided to go to shh and enable the serial port i did , but didnt work , then i used
mkdir /home/pi/nextion;(wget https://github.com/Tibus/TouchScreen-Fo … 2_3.tar.gz --no-check-certificate -O - | tar -C /home/pi/nextion -xz);cd /home/pi/nextion; sudo ./setup.sh
to fix things , it didnt work so how can i configure it

You need to first enable one of softwares, nanodlp internal nextion or tibus one. They would not play along well.
If it passes connecting screen it is highly likely communication does not happen correctly as you have enabled two reader on same /ttyAMA0

shahin can you tell me how to do it from the beginning , lets say i made new clean copy of nanodlp , then what should i do now to enaml the ttyAMA0 to make the nextion work ?
Offline
Just follow on-screen help, it should be enough. If you want easier way to use it, just use usb-serial adapter to connect nextion. No additional step needed to enable it.
Offline
and where is the on-screen help ? and what usb serial adapter do you suggest ?

Click on question mark above input box.
FT232 based USB/serial adapters working great.
