Been following your Nextion tutorials and I like the way you present the videos leaving some parts unedited where you make typos or other minor or mayor mistakes and then correct these when running debug. Helps with methods of fault finding. Comments from the editor appreciated during the video. Makes me pause and go look what he has picked up and eventually I hope to pick up those items while watching and learning.

Thanks for the nice remarks. I started the channel because I had trouble remember things and wanted a way to go back and review topics. I thought KZbin would be a good way to store my ramblings for free. I noticed that a lot of videos on KZbin have the authors creating the projects without a single error or issue while I would spend a few hours trying to figure out why my version did not work. So I decided that if I was messing up then probably other people viewing it are probably also having issues so I left the errors in. I get some negative comments about the editor but I think it is a good way to point out errors with a little humor. I have been slow to put out videos. I don't like the way KZbin sorts my videos. I am trying to rework www.cheapcontrols.com so people can more easily find my content on certain topics. Thanks for watching.

Nice now I know that anything entered into the keypad has to be done in post initialises event, its a little annoying but works. Grateful for your videos.

[@CheapControls]

Glad it helped and thanks for taking the time to comment.

@@CheapControls Hi just wondering if there is a way for the keypad come up without the previous value ie blank.. as it seems a little annoying to delete the current value then enter in the new one, any advice would be welcomed.

[@CheapControls]

I cover that toward the end of this video kzbin.info/www/bejne/joS2h6eIaZKWm7c

Another timely solution for my project. Thanks.

[@CheapControls]

Thanks, This was just a short one. I have been rethinking how I want to do the videos. I am also reworking the cheap controls website to make it easier to find videos on certain topics.

[@tiptoucher3694]

Exactly what I was looking for and explained for simple folk like me, thanks!

I'm new to the Nextion and some of the features (quirks) are not very intuitive, these videos are super helpful. I was just thinking about how to limit the values entered into an n or x box using a keypad. Thanks

[@CheapControls]

When you enter data in a keypad the page refreshes. You can check the value on page load and adjust to an acceptable value. Like of the vale should be 10 - 50 and someone enters 55 have it check the box for value greater than 50 make equal to 50. Hope that helps and thanks for watching.

[@bentleyjarrard885]

@@CheapControls Thx, I was able to set up a number of "if" statements and they worked per your instructions. The automatic page refresh with the keypad entry is a big problem since it takes priority and happens before any other commands are executed. If I try and save a new keypad value for later using "wepo", the page refresh happens first and pulls in the existing value before the new one is saved. Basically means you cannot have a page level "repo" command so the .val is always sychronized with the last entry you made. Nextion really needs to add a TRUE .val field that can be changed and record the last user entry and actually call the existing .val and .txt fields what they really are. Default values.

Not only "post-initialize" is run, also "pre-initialize" for the page is run! so as if the page has been activated

[@CheapControls]

That is a good tip.

perfect might be a stretch but thanks for the compliment.

i was working on taking long string inputs from user using alpha numeric keypad but there were few limitation like max length of 32 and couldnt scroll the text part. but now i am able to write long texts by increasing the value and also scroll the text box by changing the text box to scrolling text box . but i want to set my cursor position by click on display or by few custom buttons like left right up down . Can you help me out with that. so that editing specific part in text box becomes easy and i dont have to delete and write that whole part again.

[@CheapControls]

I have not looked into anything like that. It sounds interesting. It might be to complicated to do through KZbin comments. You might want to put in a help request at the Cheap Controls website.

[@vp.8181]

@@CheapControls yes sir sure.

[@Jacek380]

Hello, can you make your own numeric keyboard in the nextion editor and replace it with the one in the nextion editor, best regards Jacek.

[@CheapControls]

Yes you can, the built in keypads are just alternate pages, that are called when you click on a field. It is not trivial but it can be done. Good luck

[@Jacek380]

@@CheapControls Thank you for the answer, can you show how such a keyboard is made in the nextion editor so that it works like the build-in and how to replace it Regards Jacek.

[@CheapControls]

I will add it to my list of videos to make.

@@CheapControls thank you, I am waiting impatiently, best regards Jacek.

Im sorry for bumping here i was wondering if you can help me with a video. I need to send a numeric value with the nextion to an arduino and the arduino will turn of or on an led based on the value

[@CheapControls]

Have you look at my other videos. I am sure there is one that can help. Check out this one. kzbin.info/www/bejne/jKDZdXt9qJates0
