Hello, please help me.
i'm beginner with Nextion HMI. My Nextion HMI work normaly for 2 month.
but, suddently my HMI Display not getting on. I use nextion with type : NX8048T050_011R. when I upload with SD card my nextion "ON". after upload success, I restart my nextion. But my nextion LCD is black screen.
Please help me, I use this for my final project one week ahead.
When you upload by microSD card
- are you able to see the firmware upload?
Yes of course, I try to upload with SD card to ensure that my nextion get power supply about 5v. and I have check with Voltage Meter that the supply is 5V. But after upload success, my nextion still black screen.
Which version of the Nextion Editor have you been using?
Nextion Editor V0.47.
FYI, I used this version an hour ago and my nextion working normally.
Please upload HMI
this is my HMI file for my project.
while I download HMI file - did you check power supply
that it is as recommended in 5" Basic Model DataSheet
I try to connect with 5V from my PC and I've checked and ensure the voltage that according to the datasheet 5" Basic Model DataSheet.
and how about the current?
I think the current is OK and suitable, because before I get this trouble, my nextion working normally
wrong ... current consumption is not constant .... growing hmi, possibly growing current ...
Well the good news for you first
- you wont be needing to purchase a new 5" Nextion display.
So at least in that you wont need to see Vendor
Good news for me
Problem is in code, and not a BUG.
oke i use power supply in my campus, when my nextion in mode upload with SD card, ampere meter show 0.36 A and when I unplug my SD card the ampere meter show 0.16A.
So order of operation
Page Preinitialize Event
- occurs before page is loaded
- statically, with variables set as per the HMI Design
Page Postinitialize Event
- occurs after the page has been loaded
So what do you suppose should happen with
In a preinitialization event of first page?
page 0's preinitialize
page 0 command - go back to the very beginning
Now the bad news ....
you need to order fresh pizza for Gerry and I ...
