[@avrphreak9121]

Can't believe you got so few views. This stuff is golden, it is so hard to find decent tutorials on Nextion displays! I am really happy to find this! Thank you.

To make it easier to search through my videos I am add them to www.cheapcontrols.com and I will include a search feature which I hope will make it easier to find the video you want. I am doing this for myself also. I sometimes forget things and I want an easy way to find them.

Bro, loving your way of describeing all this issues and solutions along with some of your little jokes.

[@CheapControls]

Thanks for the kind words and thanks for watching.

[@aksel_brawlstars]

[@CheapControls]

Thanks

Love your tutorial(s)!! You might want to put in a comment to say that the pageX does not work any more - syntax needs to be p[x] got stumped on this for a while. I know this vid is a few years old though thanks for all your wonderful work!! Couldn't do this without you.

[@CheapControls]

Thanks for the tip. I was not aware of the change. Thanks for watching and I am glad you like them

[@CheapControls]

I went back to that video and using the complete name of the page still appears to work for me. page0 and page1. What version of the IDE are you using? I appreciate the feedback.

[@TheDefpom]

On arduino if you use”readUntil” it can check for an ending char which makes it faster, otherwise it waits for the serial timeout.

[@CheapControls]

Thanks for the tip. I have not used "readUntil" but I will definitely look into it. It is funny how you can use something for years and still learn something new almost every day. Thanks again.

Hook up the page change to the release event of the object and there is no problem.

[@CheapControls]

That is a great observation.

I am having troubles with the cov h0.val,page0.t0.txt,0 I get Invalid Variables, am I missing something? I have set both to global

[@CheapControls]

I think cov needs to be covx. or leave the comma zero off the end

[@alirezatooghi7720]

@@CheapControls I have a same problem and I used the covx with mo zero at the end, but still the same error

[@CheapControls]

@@alirezatooghi7720 Make sure you have the periods and commas correct. If you have a comma instead of a period or a period instead of a comma the ide will interpret variables wrong

Excuse me, I don’t use any mediation library. How to display page1 t1.txt="ON" text page0 t0.txt="ON" ....? Thanks

[@CheapControls]

It depends on if t1.txt is global or local. Please reply with your situation and I will supply a little code.

Serial.print("page1.t1.txt=\"ON\""); Serial.write(0xff); Serial.write(0xff); Serial.write(0xff); Serial.print("page0.t1.txt=\"ON\""); Serial.write(0xff); Serial.write(0xff); Serial.write(0xff); Notice the backslash and qoutes \" You need the backslash so the arduino knows to send the quote in the string. if you are sending a value you dont use the /" Serial.print("page1.n1.val=356"); Serial.write(0xff); Serial.write(0xff); Serial.write(0xff); Let me know if I answered your question or if I got your question wrong please rephrase it so I get you the answer you need. As always thanks for watching.
