Newbie needs help adding nextion screen to ZUMspot

Post by KB4NC »

Just received my Nextion NX4835K035_011 screen and attaching it to my ZUMspot. Someone pointed me to the Nextion facebook page to get a file for that model -- which I found from PD0DIB. I dowloaded the file, compiled it using the Nextion Editor (v.053), and copied it to the microSD card. Next I connected the screen to the TX & RCV leads on the ZUMSpot and and the power leads to a separate 5v source. I am running Pi-star v3.4.16 and changed the MMDVM display to Nextion, the port to Modem and the Nextion Layout to ON7LDS 3. I also had other layouts (G4KLX, ON7LDS 2 and ON7LDS 3 HS to choose from). I tried them all, but nothing displays. When the Nextion screen powers up, it displays:

Baud: 9600
SD Card Update ...
Size 2625222
Copy SD...
0% -- 100%
Check Data... 100%
Update Successed!

And then sits there on the white screen.

Does anyone have any guidance with this screen and hotspot?

Thank you in advance!

Are the TX and RX reversed?

Screen TX to board RX, and Screen RX to board TX?

Actually - I would greatly appreciate if anyone has a working TFT file for the NX4832K035 screen for DMR & D-STAR for me to get started with and make sure things are working correctly.

The Nextion Editor can be downloaded from Itead:
https://nextion.itead.cc/resources/down ... on-editor/

For a basic selection of Nextion screen layouts as well as the more detailed readme explanations of the differences between the layouts, see the Nextion subfolders of the g4klx/MMDVMHost GitHub page:
https://github.com/g4klx/MMDVMHost

Rob, PDØDIB, also shares his screens via GitHub: PD0DIB/Nextion_HAM-radio-screens:
https://github.com/PD0DIB/Nextion_HAM-radio-screens

Ryan, WA6HXG, also shares some nice screens and good explanations on his GitHub project page: WA6HXG/MMDVM-Nextion-Screen-Layouts:

Well then I would guess the CR1220 battery needs to be in the battery slot! Without one in there, it displays "Resource filebinver is error! 99 1" No one around has those batteries and I'm waiting on a shipment from Amazon. Hopefully this is the last obstacle!

Thanks,

That is good to hear Gene. Thank you. I was just on TGIF and heard that another ham couldn’t get his to work using the SD card but it worked with the USB to TTL converter. I have one of those and going to try it

Cheers!
