I confirm that Paul said, the secure way is the mini SDcard
You really need it !
Paul works with the "c" command of nextion,  I did'nt. I wrote my own bascom library
I use a serial port to send and to receive from the Nextion display
and another to debug
Yes the program firststep display "hello word" then a loop with write "hello word 1" to "hello word 12345678 " with another back color
-----------------
Paul , thank you for the link about nextion tutorial, it seems easier than the help from Nextion

I have the Powerpoint forgotten 
sorry for stupid question, but english is not my native language: a simple hello-world-programm will not be displayed without the large sd-card-procedure? right? because font files are missing? thats why are no response from the display with only bascom-programm from JP?
no error-message or any thing else, instead the displaying the nextion animotion? |

To display hello world you need to-
1- create a text box with nextion editor
2- load program from editor to SD Card
3- put SD Card into nextion display so that it loads program created with nextion editor
4- send to "hello world" to text box on display via the serial port |

Yes it does all the hard work.
It can also be programmed to do processing
I just used an old mini SD card that was being used with my bascom webserver project
If you put the nextion editor on your computer
you can load the project files I have posted
like bascom it will run it on your computer in a simulator.

Hello JP,
sorry, but i am very frustrated. in your powerpoint first stap is blue/yellow connected on rx0/tx0..on your bascom example is it tx1/rx1....
how baud-rate is right? how can i find the right baud rate for bascom..
i try and try but after sucessful nextion editor session with sd card updating is over. no "hello world" on Display, only "nexttxt".. |

The nextion display is set to 9600 baud at the start.
You have to write code in the nextion editor to change from this.

hi,

Yes it is right , on the last exemple I use another couple of port because I use 2 serial port
1 for Debug tx0/ rx0 com1
1 for nextion tx1/rx1 com2
on the power-point Idid'nt use debug
Now I use my own card , not a arduino , but It is approx the same wiring 
| Code: |
$regfile = "m1284pdef.dat" ' "m1284def.dat"
$crystal = 16000000 ' 11052000
$hwstack = 300 '300
$swstack = 250 '200
$framesize = 250 '300
Config Submode = New
Debug On 'Off 'if you debug off you remove all print from USB port
'*****************************************************************
'* CONFIG BUFFERED USART FOR USB *
'*****************************************************************
Config Com1 = 115200 , Synchrone = 0 , Parity = None , Stopbits = 1 , Databits = 8 , Clockpol = 0
Echo Off
Config Serialin0 = Buffered , Size = 30 'RX from Terminal
Open "COM1:" For Binary As #1
Const Usb = 1
'---serial port-------------------------------------------------------------------------------------------------------------
Const Nex = 2
Config Com2 = 115200 , Synchrone = 0 , Parity = None , Stopbits = 1 , Databits = 8 , Clockpol = 0 '19200 modif pour ecran intelligent
Open "COM2:" For Binary As #2
Config Serialin1 = Buffered , Size = 50
Config Serialout1 = Buffered , Size = 30
'M1284------------------------------------
' RXD1= yellow to PD3
' TXD1= Blue to PD2
'*******************************************************************************
$include "declaration_nextion.inc"
$include "sub_macro_nextion#3.inc"
|
I use submode=new
As Paul said you must add bauds=xxxx the speed you choice in the Nextion
then debug and save in the *.tft file
This file must be copy to a mini-sd card and charge it in the display
what can I do more for you ?

sorry, but my english is very bad.
i have only one chance: connect blue/yellow to rx0/tx0
it looks like the "problem" is on your code. bas and inc work with com2..but i need com1, because i can not connect to tx1/rx1.
can you configurating your code to com1? i believe this is the main propblem by my circuit and your code.
i configurated the nextion display with your tutorial. some baud rates...i skipped the picture chapter, becaus error on compiling. without picture the nextion Editor compiling perfect.
of course i have the compiles tft-file on sd card  |
