#85 Nextion Display - connected to Arduino in debug mode - Nextion tutorial

[initiald]

I managed to get it working with simulated debug but not with my actual nextion. However, my nextion works given parser is zero and my pins are blue wire to tx0 and yellow wire to rx1 on arduino mega, through keyboard typing in values.

However, this doesn’t work for me when I use the ide code, and I don’t know why. What am I missing?

Hi,
Is there a way to control the hardware control flow lines of the USB to serial adapter from the debug window? I looking at trying to use the Nextion editor as a remote monitoring terminal for my microcontroller in a project and was hoping to use the RTS line to trigger the reset pin on my micro in the event I need to reset my micro for some reason.

Thanks

Thanks a lot for your tutorial !, I recently started using Nextion I have problem in the display of data in Debug of Nextion, and I did not understand the role of Serial.write here in this program.I will be very grateful to you if you can answer me

What version of Nextion did you use here? It seems that they removed the option to debug with a serial cable in the latest version - v1.63.3

it doesn't works for me
I have a USB-TTL cable.
RX to TX and TX to RX and power connected to the Arduino.
No reaction.
So I can't upload a sketch to the Arduino, it won't be found.
If I connect the Arduino with a USB cable then I can upload the skatch.
But nothing happens in the Nextion Editor when I start in debug mode.
can you help me?

Does anyone know why I don't get the option "USER MCU INPUT"? And how can I solve it?

Thanks for your tutorial! I have a problem: no information is coming from the Arduino to the Nextion display. Just an empty line in Debug mode. I connected the Arduino to the COM5 port with a separate cable and connected the Nextion display through the TTL adapter to the COM4 port. How can this problem be solved?

Have you ever tried conecting the arduino to the PC so you can use Nextion Editor Debug and to a physical Nextion at the same time, so you simulate having two screens?

Greetings! how can you fix the "access to com7(my arduino port) is denied
? Thanks <3

Hey i have a little problem while sending value with arduino, when i click on every button in the debug mode that send a return error 04 FF FF FF Parse Invalid Pic ID so when i want a "if (datareceive == "Anything") that doesn't work if you have time to respond i appreciate
