Hi, I want to know is what we can use Json Format for Arduino communication with Display
Only if you can format JSON to replicate the Nextion Instruction Set
ok can you give link ( if available ) how to do this
Sorry. But the fact you ask for a link
perhaps indicates beyond your abilities and out of reach
This would be your duty as programmer to create
The Nextion Instruction Set is Text based input, binary mixed output.
What you use for your MCU, programming language etc is also your choice.
Programming of the MCU is user domain.
Iteadlib Arduino Nextion Library is free to use and modify
I would suggest using it as a quideline to assist you
But why build a text based interpreter (JSON) to interpret text commands?
On an MCU, such would deplete the MCU resources without work being done.
