nextion display flowcode 10

[bdjbuster]

Hello, I am using Flowcode 10 with a Nextion display, but I can’t get the program to work. It does work with Flowcode 8, but that version doesn’t support the Nextion display, so I created something myself using UART1. Can someone tell me what I am doing wrong in Flowcode 10? Both programs are available to download.

Hello,

There's a demo here that should be useful for you.

Hello, I watched the demo, but it uses the display in a completely different way than I do. I use the display so that when you press a button, it sends a number to the Arduino, and then I handle that in the code. I’ve programmed both parts like that, but it doesn’t work. Could you take a look at my program?

Hi I looked at your program and it looks like you're not making use of the returned value.

I think the example in the wiki is useful and should be the same way you are trying to achieve.

Thank you for your response, but unfortunately it doesn’t solve the issue. I have programmed the Nextion display in such a way that it works correctly with Flowcode 8. I achieved this by making the display send a number as a string whenever I press a button on it.

So when the Nextion sends a message, how can I receive it in Flowcode 10? And if that’s not possible, I would have to reprogram all my displays, which I would prefer to avoid.

I completely changed my program to match your example program. It is working now, but the display and Arduino only respond when I press the same button a second time.

I attached the program. Could you please check what is going wrong?

Hello,

Sorry to hear you've had to rework your code. I've hopefully spotted what's causing the issue and it should be resolved for you now via the library updates.
