Nextion Editor

 Anyone have suggestions on installing the editor software. I keep getting " Nextion editor setp ended prematurely because of an error"  I am using Win7, any ideas?



Update.  When trying to install EXE on computer, it would not install. Once I put it on a USB drive , then it installed.

Hi,@Rkonnen. Maybe something wrong. I remember that the old version can not be installed in C/:,but the V0.21 has fixed it. You can download the lastest EXE here: 

Hope everything goes well !

 Question: Can someone help me out on this. I am trying to read an analog pin and write it to the Nextion 2.4. I have tried several different sketch combinations. Can some body just show me how it is done , so I can see what I am not getting.


You can try the tutorial from ITEAD

Use the code starting with "float getValue;".

Don't use the code starting with "#indluce nextion.h", it is not compatible with the new Arduino library from ITEAD.


Could you add a comment in your tutorial to explain that the code starting with "#indluce nextion.h" is not valid any more with the new library.

By the way, it should be "include" instead of "indluce"...

Raphael,  So what am I missing below?

float getValue;
int value;
float oldvalue;

void setup() {
void loop() {
getValue = analogRead(A0);
if (getValue = oldvalue)
{ oldvalue = getValue;
getValue = (getValue * 100 / 1023);
value = getValue;



In your code you have "if (getValue = oldvalue)" with one "=", but it should be two "==".

With the code "getValue = oldvalue" the value of getValue is changed back to oldValue :-)

  Thank you, that worked .


just wondering why the latest link in the wiki still points to an older revision .21

the update loads the newer 26 version though

Hi,@Charles lakins.

We have updated the download link.

The latest version is V0.26 by now.

Hi, can anyone give me some information on how to work with the new waveform component. How to send commands to it.


The command is : add cmpID, ch, val

we have updated the wiki of instruction set:

The tutorial of waveform component will be posted soon.TKS

The command is : add cmdID, ch, val

Maybe it should be cmpID instead of cmdID.

cmd = command

cmp = component

It should also be "ref cmpID" instead of "ref cpmID"

It is also nice if you insert links using the dedicated icon. 

Be a good example for the users of the forum :-) 


Here is the example of waveform component in Arduino_Nextion_library,
