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?

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...

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 ...

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 availa...

Hello, I have written a program using a Nextion display with an RXINT. However, when I use this, I get an error code. Does anyone know how I can solve this? I want to use the RXINT for controlling the display. I have done this in the past with older Flowcode versions using a Nextion display, but bac...

Hi Martin, I found the problem. There was a fault in the PCB of my DAC: a 10 kΩ resistor was placed between the SDA and SCL lines. Because of that, the DAC was able to receive communication but not send any. Apparently, Flowcode 10 requires feedback (return communication) to function correctly, wher...

Hi Martin, Thanks for your response. It's still not working on my end with the four DACs I'm using. However, if I use a ready-made DAC, it does work with Flowcode 10. Also, when I use the I2C address scanner from the Arduino IDE, I don't get any response from the four DACs to indicate their addresse...

Hello Martin, I have some additional information for you. I am using an MCP4725 in Flowcode 8, but there wasn't a separate component for it, so I used the MCP47X6, and that worked fine. When I open the program in Flowcode 10, it takes over. However, Flowcode 10 also includes the MCP4725. So I just t...

Hi, I tried it with one DAC, but it still doesn't work. When I check the SDA with the oscilloscope, the communication looks very different compared to when I create the same program with Flowcode 8. With the oscilloscope, I can also see that the microcontroller is not freezing

Hello Martin, thank you for your response. Could you give me an indication of when you might be able to get to it? That way, I’ll know whether I should wait for it or try another way to get it working.
