ESP- radio with Nextion display

[middelbh]

I succeeded to use your program with my Wemos mini d1. Works great! Now I want to use a Nextion display as a user interface, allowing touch control. Whatever I try, the Nextion will not react.. if I use the program below separately it works, but including it in Esp-radio there is no reaction in my textbox (t0).

include

include

SoftwareSerial nextion(d3,d4);// Nextion TX to pin d3 and RX to pin d4 of Wemos d1 mini Nextion myNextion(nextion, 9600);

in Setup: myNextion.init(); myNextion.setComponentText("t0","4321");//symply to test if info is sent to the display

Hope anyone can help!

Did you remove the references to d3 and d4 in the radio software? Does SoftwareSerial work in combination with the normal Serial I/O?

[middelbh]

As far as I know I removed all references to d3 and d4, and normally SoftwareSerial works together with normal serial.. I will do a separate test for this lateron..

[middelbh]

By the way, what possibilities exist to change your system into a library? That would make programs more clear to debug...

[middelbh]

@Edzelf, I tested, Serial and SoftwareSerial do work in combination...

[Edzelf]

I ordered one, so I can test (in a couple of weeks). I'm not planning to turn the sketch into a library.

[Edzelf]

Which Nection library are you using?

[middelbh]

I use nextion library from: https://github.com/itead/ITEADLIB_Arduino_Nextion

[Edzelf]

The description of this library does not mention the ESP8266 as a supported board. Read issue 25 of the itead library github.

[middelbh]

Correct, but I used it in several other test situations without problems... just check the right GPIO’s and it works. What I will try tomorrow is attach another arduino to the serial ports that go to my nextion and see if teh softwareserial works...

[Edzelf]

Good idea.

[middelbh]

Tested, but looks like softwareserial does not work in Esp-radio. I will try to find the cause..

[middelbh]

Got it working now, I will have to cleanup my sketch, I will then show what has to be done to the program to get it working. Grtz, Hans

in the initialisation of the program I added: int d1=5; int d2=4; int d3=0; int d4=2; int d5=14; int d6=12; int d7=13; int d8=15; and

include

include

SoftwareSerial displayPort = SoftwareSerial(d4,d3);// Nextion RX to pin d3 and TX to pin d4 of Arduino Nextion myNextion(displayPort, 9600);

Change Pins for VS1053 module: as my wemos d1 with battery does not have a d0 but a d8

define VS1053_DCS d8

Delete:

define TFT_CS 15

define TFT_DC 2

and

define BUTTON1 2

define BUTTON2 0

define BUTTON3 15

In TIMER100 remove all regarding BUTTON1, BUTTON2 and BUTTON3

In SHOWSTREAMTITLE comment out: if ( ( p1 = strstr ( streamtitle, " - " ) ) ) // look for artist/title separator {

*p1++ = '  ' ; // Found: replace 3 characters by newline

p2 = p1 + 2 ;
if ( *p2 == ' ' )                           // Leading space in title?
{
  p2++ ;
}
strcpy ( p1, p2 ) ;                         // Shift 2nd part of title 2 or 3 places

}

displayinfo ( streamtitle, 20, 40, CYAN ) ; // Show title at position 20

And replace by:

myNextion.setComponentText("g0",streamtitle); //I've a scrolling text on g0 in Nextion myNextion.setComponentText("t0",String(vs1053player.getVolume()));//I've a text at t0 myNextion.setComponentValue("z0",vs1053player.getVolume()); //I've a dial at z0

In SETUP :

add in the beginning:

displayPort.begin(9600); myNextion.init();
myNextion.setComponentText("g0","Radio started");

change system_update_cpu_freq ( 160 ) ; to system_update_cpu_freq ( 80 ) ;

and delete the lines:

pinMode ( BUTTON2, INPUT_PULLUP ) ;
pinMode ( BUTTON1, INPUT_PULLUP ) ; // Input for control button 1 pinMode ( BUTTON3, INPUT_PULLUP ) ;// Input for control button 3

Hi @middelbh ,

I recently set up ESP Radio without display, but I have one Nextion display in storage. Is it possible for you to upload ino file and describe changes made in pin connections?

TIA - Mandar
