Hello,
I'm currently working on my motorcycle Dashboard project with a 3.2" Nextion HMI screen.
I can display my data on the screen without any problem but as I want to receive data from the screen (button pressed on the touchscreen), it doesn't work.
In my nextion editor in debug mode I can simulate the feedback as I press the button. But in the arduino IDE the serial monitor displays nothing and I can't interact with my program which is widely based on this example (doing something after recieving a specific HEX message).
However I can see the message from the Nextion in the serial monitor using the code given here
As a noob, there is probably something I didn't get.
Is the feedback from my screen supposed to be in the serial monitor ? What exactly displays that serial monitor ?
Thanks
