Nextion display does not work

[wa8lbz]

I have the VS1053 module (MP3/ACC decoder), VS1338B module (IR), KCX_BT_EMITTER module (Bluetooth transmitter), BUT not the Nextion NX4024T032_011 display is not working. Other than the display the radio works fine.

I connected a oscilloscope to the RX2 in on the ESP32 module and see the signal displayed in the attached picture. The signsl stays the same after switching to another signal. I don't know what the signal should look like at the RX2 pin but this is what I see.

Is there anyone who built this project using a Nextion display and got the display working. I have tried everything I know but can't fix the problem. The display is brand new. I will greatly appreciated any help I can get.

[Edzelf]

Connect your RIGOL to the TX2 pin of the ESP32 and check if there is a signal. Remember that lines should be crossed: TX2 to the Nextion RX and RX2 to the Nextion TX.

[wa8lbz]

The blue lead on the display is TX and it connected to the RX2 pin on the ESP32. The yellow lead on the display is RX and it is connecte to the TX2 pin on the ESP32. Yes there is a signal on the ESP32 TX2 pin.

[Edzelf]

I will test this set-up again.

[wa8lbz]

Here is a new picture showing both the Nextion display RX anf TX. The yellow trace is the RX signal and the blue trace is the TX signal. I changed the sweep range to get both signals on the scope at the same time. I hope this helps.

[Edzelf]

I fixed the NEXTION display.

[wa8lbz]

When I tried to compile the new information, I got these error message when compiling: Compile Failure.txt

[Edzelf]

Show me your config.h

[Edzelf]

It looks like you have defined both NEXTION and DUMMYTFT. Just define one type of display.

[wa8lbz]

Config dot h.txt

[wa8lbz]

After making some changes, I got the pio run -t upload and uploads to upload without problems. However, not only does the Nextion display still not work but the radio no longer plays. This happened after down loading and installing the new zip files.

[Edzelf]

Just download the project. Compiles without errors, Radio plays, tested with DEC_HELIX_INT and NEXTION. I found that the NEXTION did not update program info. Fixed that in NEXTION.h and NEXCTION.cpp.

This is what I did: What I Did.txt

Hi, I've been following this for a while and decided to give it a try. I did the test with a pcm5102A and Nextion NX4832T035_011 this is my log, can't connect to wifi also not with web interface. keeps rebooting.

[wa8lbz]

Here is another clue. This the Serial Monitor printout when power is applied to the radio. And as far as I can tell the VS1053 is properly installed and it is defined in config.h. Serial Monitor 1.txt

[Edzelf]

What is wrong with GPIO18. This should be the SPI clock, but it is pulled LOW.

[Jefke1]

I used a new Esp32, radio plays well, in serial monitor Nextion text is visible but the display remains blank. I have used a standard and an enhanced display.

About GPIO18 == ??

[Edzelf]

Have you uploaded the nextion program to the nextion? Is the nextion baudrate correct?

[Jefke1]

uploaded with SD card and TTL, baud rate 115200. Set GPIO18 ==>> HIGH Settings or OK but no result. Radio plays well, volume control works fine but not visible in the serial monitor.

[Edzelf]

I don't understand how you get this JSON info and what it means.

[Jefke1]

it's very weird, when I open src main.cpp in pio I get 42 JSON errors. all related to Display or TFT.

[Edzelf]

Are you sure you have defined one display type in config.h?

[Jefke1]

very sure, here's a screen shot.

[Edzelf]

If it compiles without an error, the problem is in intelli-sense. Sometimes a clean-up will help. There is a button for this, looks like a garbage can.

[wa8lbz]

I performed a clean up as you suggested and got the serial monitor printout during pio run -t upload: pio run -t upload 1.txt

[wa8lbz]

Could this be a problem? The last serial monitor printout for pio run -t upload shows Python to be version 3.1. The command Python --version show it to be 3.9.10.

Maybe there is a problem with preferences. When issuing the command pio run -t uploadfs, specifically what is being uploaded? defaultprefs.txt, ESP32_Radio_init.ino or something else. Both of these have been changed for my setup.

[Edzelf]

It looks there is something wrong with COM7. Usually exit Platformio will help, otherwise power cycle your PC.

[Edzelf]

-t uploadfs uploads the files in the data directory to the SPIFFS. -t upload uploads the sketch.

[Jefke1]

I did a clean up. Everything uploaded, compiled without errors. Nextion doesn't work, only flickers on startup. No signal on Pin 16 - 17. Serial.txt

[Edzelf]

Check these lines in NEXTION.h:

// Various macro's to mimic the ST7735 version of display functions
#define dsp_setRotation()                                          // Use standard landscape format
#define dsp_print(a)        NEXTION_dsp_print(a)                   // Print a string
#define dsp_println(b)      NEXTION_dsp_println(b)                 // Print a string followed by newline 

[Jefke1]

Identical to yours.

[wa8lbz]

I hope this information helps resolve the problem. My Stuff.odt

[Jefke1]

Problem solved. In the Nextion Lib. ==>> Nextion.cpp change nxtserial->begin ==>> from (115200) to ( 9600 ) That solved my problem.

Ed thanks a lot for your time.

[Jefke1]

Still a problem. Prev and Next do not work with the Nextion or in the web interface. Prev-Next.txt

[Edzelf]

I will look at that later.

[Edzelf]

You can set the NEXTION baudrate by placing the command "bauds=115200" in the Preinitialize event of page0. I have added this instruction in both ESP32-Radio.HMI and ESP32-Radio.tft now.

[Jefke1]

Everything adjusted. Result remains the same.

[wa8lbz]

Changing the statement from nxtserial-> (115200) to 9600 in the nextion.cpp file brought my Nextion display to life. This fix was brought to my attention by Jefke1. Now the remaining problem is shown here: Power Up Serial Monitor.txt

[wa8lbz]

A test of Port 80 reveals this:

[Edzelf]

What does it mean? You try to connect to port 80 of your Windows machine? This has nothing to do with your Nextion nor the ESP radio.
