    One picture. With the xpic command, you cut and display what you currently need.

    In the project, insert the same picture that you put here (containing all cases of progress bar).
    With the xpic command you can cut a fragment out of this image and display it on the screen. The xpic command can be used locally in the LCD or sent from eg arduino (sendcommand ("....")).

    You absolutely must have every 1%? I think that, as you showed in the previous picture, every 10% for a pest is not bad.

    Hello

    The first time I have to use this display, the project I want to copy is: http: //souliss.net/articles/DST/ I made the project and it works great but.
    In the project in the HMI file there are words in some exotic language I would like to change them. So I ask colleagues with more experience whether it can be done in Nextion Editor, or do I have to design the HMI file from scratch.

    best regards

    I don't see any exotics in the display design itself. Paste the screen where you can see it.

    Hello

    On "page 1" upper left corner.
    On "page 2 and 3" everything in some language I don't know, probably Italian.

    Hello
    I took pictures in the right resolution and I had no problem with pasting them to the "picture" on the bottom left in Nextion Editor, so I have no problem with pasting them to the "page" on the right at the top.
    What am I doing wrong?

    Good morning
    I need help. Someone could open the hmi file at home. There is one TextSelect element in the project and it causes NextionEditor to hang during compilation.
    I wanted to check if this only happens on my PC.

    I will go classic, I can see that you are combining with the new display

    Well, if I change the drag attribute to yes, it hangs when compiling.
    I am using version V1.61.2 on Win7

    Hello.
    I have the screen as you can see.
    At the bottom I have a numeric field n7, a text field t7 and a button that changes the type of timer with the code:
    Code: text Expand Select all Copy to clipboard
    
n7.val+=1
if(n7.val>4)
{
  n7.val=1
}
if(n7.val==1)
{
  t7.txt="monostab: 0 na 1"
}
if(n7.val==2)
{
  t7.txt="monostab: 1 na 0"
}
if(n7.val==3)
{
  t7.txt="generator od 0"
}
if(n7.val==4)
{
  t7.txt="generator od 1"
}



    There is also a timer on the page which after loading the page updates the string t7 according to the value of the numeric field n7 after loading the page
    Code:
    Code: text Expand Select all Copy to clipboard
    
// ładuje opisy
if(n7.val==1)
{
  t7.txt="monostab: 0 na 1"
}
if(n7.val==2)
{
  t7.txt="monostab: 1 na 0"
}
if(n7.val==3)
{
  t7.txt="generator od 0"
}
if(n7.val==4)
{
  t7.txt="generator od 1"
}
//////////////////////////////////
if(n6.val==1)
{
  t6.txt="tranzystor"
}
if(n6.val==2)
{
  t6.txt="triak"
}
if(n6.val==3)
{
  t6.txt="przekaŸnik"
}
if(n6.val==4)
{
  t6.txt="beep"
}

    As I change the value in the first two X-type fields using any keyboard, the value of the generator type is reset to zero. (this also applies to the type of output)
    The question is where is the cause.

    Thanks for the fix, but what was the error?

    I showed it in one of the films (local vs global, I think).
    The keyboard is the next screen and on returning from it all local variables are cleared and the global ones remain unchanged

    Thanks, I'm only sitting in it for the 3rd day but it's still cool because the previous screen was 1000 lines on the UTF library.
    Sometimes, as always, he writes faster than I think and read.

    Hi,
    I have a nextion display from the intelligent and arduino mega series, I would like to use gps to display the current speed and distance traveled on the display. Could someone explain how to do this?

Topic summary

A new video tutorial series for NEXTION displays is being developed, focusing on various functionalities and programming techniques. Users discuss the capabilities of NEXTION displays, including sending commands, managing timers, and handling multiple pages. Key topics include using buttons to control outputs, sending data from Arduino to NEXTION, and managing display states across different pages. Users share code snippets for specific tasks, such as updating text fields based on variable values and implementing timers. There are also discussions about troubleshooting issues related to memory usage on Arduino, interfacing with GPS modules, and optimizing communication between Arduino and NEXTION displays.
