I am looking for someone to tell how to put this firmware into the Arduino IDE? I have not unzipped it yet....
I have followed KD8CEC this, far and do I need Xloader to do it? or how? I tried to download Xloader and it said it was a bad site to go to?
Could I use Balena Etcher?

I used the arduino program to put on the firmware, but...i had some problems until i switched the arduino program to "old Boodloder"

Jon,
Before you try to flash the KD8CEC firmware, do you have the Nextion screen and the correct program for it?? The KD8CEC firmware will not work with the stock uBITX screen.

Since Xloader is free, the author did not register the program with Microsoft or any other program verification site.? As such it will trip the warning when you go to download it.? I have bypassed the warning and not had issues.? I cannot vouch for the site that you are using but would think that it is OK.

If you do not want to trust the Xloader site/program, then you have two options:
1 - download the source code, set the correct #defines in the ubitx.h tab in the Arduino IDE.? The zip file contains only hex files that need a hex loader.? Balena Etcher would not work as far as I know.
or
2 - follow the instructions in this link to use the Arduino uploader without compiling the source:



To make sure all know how to help you, can you tell us what you want to accomplish by switching to the KD8CEC firmware??

I do not have the Nextion yet, but it is on order. You answered what I wanted to know you cannot use the stock uBitx screen. I thought that!
As for the Xloader, and as you say it is just my Firefox that is trying to stop it.
Thanks for the information, that helps a lot. I am to old for this (87), but I like playing!
Happy New Year stay safe.

One other thing you said about having the correct program for the Nextion? where does that come from??

Jon,
That depends on which Nextion you have purchased.? Also on what features you may want to add.? A good source is ubitx.net in the download section for larger screen sizes.? For the 2.8" Nextion that can be forced into the stock case you can try this location:


In the above are also the wiring instructions for the screen.

One last point, some of the screen programs were built using the older LTS Nextion editor, and will not fit into the 2.8" display using the newest Nextion editor.? You need to worry about this only if you want to make changes.? Just be sure to get the correct size and model (Basic or Enhanced) tft file that matches your display.? Be sure to load the screen files before you install the Nextion into the uBITX, as the default orientation puts the microSD card slot on the bottom (this can be changed if you take the source and modify it with the editor).? All you need is a 5volt supply to power the Nextion screen.? Some of the screens come with a microUSB power tap that can be used for the setup.

Have fun and Happy New Year!

The site uBitx.net does not show the 2.8" screen software? So you can use the basic Nextion?? and also the Enhanced would be better??
I do know the wiring for it I found it online.
Happy New Year
Evan

Try this link for the tft files:


I have not seen a difference in performance, and had problems finding a tft file for the enhanced.? I would go with what is available, though the enhanced may give more options if you want to modify the file.

I downloaded Xloader that's OK. But I am still confused with the Nextion firmware I still cannot find it,or I do not know what I am looking for?
Thanks
Jon

Evan
Bye the way if I did not tell I ordered a 2.8" Nextion .

Jon,
The prior link will get you to a zip file with the tft file that you need (at least one variant).? To transfer the tft file to the Nextion display you format a 32gb or smaller microSD card and transfer only the file that you want loaded onto it in the root directory.? Then plug the microSD card into the Nextion with the power off, Turn on the Nextion by connecting 5volts, the file should load, and give an OK.? Remove power from the Nextion. Remove the microSD card. Then verify that the home screen comes on when you apply power without the microSD card.

Anytime you want to change the Nextion screen program, just repeat the above with the new tft file loaded on the microSD card.

I thank you, but which one of the 5 files do I download? HEX1.1.zip
?????????????????????????????????????????????????????????????????????????????????????? MM1.1.zip
?????????????????????????????????????????????????????????????????????????????????????? UBITX_Nextion_GUI_V3.zip
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?? UBITX_Nextion_Temp_V1.zip
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?? UBITX_TJC_GUI_V3.zip
Is it the HEX1.1.zip, just a guess!
I have also looked at videos on how to connect it up, but none that I have found tell you how to download the software.
I thank you Evan for all your help with this matter.

Jon?

Jon,
It is the UBITX_Netion_GUI_V3.ZIP

download and unzip the archive.? There is both a 2.8" Basic and 2.8" Enhanced tft and HMI files.? The tft are the already compiled files to transfer with a microSD card.

there is a filenaminfo.txt file in the archive that explains the naming convention:

I thank you! I will followup if OK. I have formatted the SD card fat32.

Jon

Evan
Just a follow up. I did it and and put it on the SD card ubitx_28_E.tft . This is just atrial run and it seems to have work OK!
I will play with it some more.
Thanks.
