Nextion Display and 2 Arduinos

Projects General Guidance
1

Hello to every one,

I am doing a project that consists of displaying and receiving some data from a Nextion display. The problem is that I have 2 Arduinos and each of them is getting data from different sensors. Is it possible to hook up both Arduino to the Nextion display and send data to it? In other words, can I connect the TX and RX ports of the first Arduino to the TX and RX port of the display and the TX and RX ports of the second Arduino to the same TX and RX port of the display?

Thanks for the help,

Enzo

No !

But you could use software serial to communicate between the Arduino's and use one UNO to connect to the display .

It seems to me highly unlikely that you need 2 Arduinos for your project. Why do you think you need 2?

It is a common mistake for people new to micro-controllers to think that 2 is better than 1, when it almost always is not.

The sensors are Hall effect sensors therefore I need to read pulses. I use attachInterrupt() however I am using Arduino Nano and there are only two ports dedicated for attachInterrupt().

What is the frequency of the pulses? It is not usually the case that you need interrupts to read pulses.
