Adjusting communication for specific screen ?

[pavelsplavel]

I want to connect specific screen to duet 2 wifi.
Here is instruction how to implement it with Marlin:
Marlin code is written in C and C++, the developer can add translation code to Marlin so when it receives instructions starting with 5AA5, it can translate those instructions into G-code language to identify. Then it will convert the content that needs to be fed back to the screen into the instructions starting with 5AA5, and send it to the screen for communication interaction.

How to implement it using ReaRap for duet? Thanx!

Ad a start the Firmware for the PanelDue is here:
https://github.com/Duet3D/PanelDueFirmware

The connection to the Duet is over a standard UART

@T3P3Tony Thank you for sharing firmware!
Do you know to which file i can add "5AA5" instruction ?

@pavelsplavel said in Adjusting communication for specific screen ?:

Do you know to which file

Can you describe what you are trying to do?

This is not as simple as "Add the 5AA5" instruction.

@alankilian so i want to provide communication between DWIN screen and duet 2 wifi board.

Here is tech doc for screen:
Development Guide of T5L ASIC_20200624 .pdf

So i have two options=)

1. Add some instructions to firmware(need just find location in code)
2. Get DUET communication protocol and address to drive the serial port.
