I have read all posts on this topic, but can't find the answer to my problem which is that raduino output does not fill the entire area of the nextion display.
I have a 3.5 inch enhanced nextion.
I copied ubtix_35_E.tft to a 16 GB microSD card.? No other files were on this card. I put the microSD card into the card holder of the nextion.? I powered up the nextion, which then uploaded the .tft file successfully.
I powered down the nextion and removed the microSD card.? I used Xloader to upload the hex file UBITX_CEC_V1.200_NX_S.hex to the raduino.? It uploaded OK.? (I made sure the upload speeds in Xloader and in the com port properties were identical).
I connected the nextion to the raduino and powered it on.? Up came Ian's uBITX screen, but it only occupied the top left corner of the display.
I am obviously doing something wrong.? Can someone please put me on the right path?
Thanks, Kevin VK3DAP / ZL2DAP

I have not tried this file from Ted in the following link, but it did work for someone else:
/g/BITX20/message/67572

The issue is the .tft file is just a quick change to a compile option and not a true resize of the screen.

There may be conversions that you like better than the one from Ted.? I would search through the messages and files on the board.

kevin -- I had the same problem with my 4.3 screen.? It is a bit of the wild west out there, so you just have to search, try and hope to find a TFT file that works for your screen. Sharpen your google search skills, and search like mad.? All of this is true because I wasn't willing to dive into nextion file editing and had no interest in rolling my own, so I had to depend on the good efforts of others.? So thank you all the "others" out there. You rock, as they say.?

For the 4.3, I finally found this file?unitx_43B7_pd5dj.tft? out there that worked perfectly.

I love the 4.3 screen size by the way.? It seems a great compromise for good readability and has enough screen room for my stupid fingers. haahah.

Hi Kevin,

The hmi/tft files over 2.8 are meant for you to resize yourself. It's not an easy task. I have several clean iterations for the 3.5". There are also a few floating around...you have to search for them. Rich Neese has a few that look totally different than what CEC gives as a template. The functionality is the same...just a different layout. All of my files are for the basic Nextion. I believe Rich has some for the enhanced. If you join the facebook group, you'll find many discussions. Evan's suggestions will also get you started.

Anyway, if you get stuck, please let us know...

I know I had to search high and low for a 3.2 tft. And now I have a 5” and I had to redesign my own hmi file using CEC original 2.8 hmi. Some photoshopping and learning the nextion display editor and figuring out how the layouts are configured were required. Oh boy.?

Thanks for all replies. At least the small display I have responds to touch!
