Serial debug screen - passive device

I have two nextion screen and now I want turn one as serial debug screen.

The idea is that nextion screen is a passive screen that receive strings by serial port of other microcontrolor and display them. This ideia is like a putty or other terminal debuger. 

But with nextion we need programing the microcontroler of our embedded system  with command for the nextion.


It's possible create this idea for a nextion screen?


Thank you,

I am now reviewing all of the Feature Requests, this will take some time, patience please.

Please post questions that are not feature requests in the Free Chat Section


A serial pass thru with a minimal MCU can be created

Text received from one side to be passed to the Nextion would need encapsulated and terminated.
