[Question] How to get unique screen device id?

本帖最后由 Hotter 于 2022-4-10 18:48 编辑

Hi, I have DMG85480C050_03WN and DMG80480C043_02WTC screens.
As I understand I can get unique screen device id with this command:
5AA5 04 83 0000 04
But I get the same screen id with both screens:
5AA5 0C 83 0000 04 5A00 001C 0000 0000




How do I get unique screen device id?

Hello! Does your screen use the 5AA5 frame header protocol that comes with DWIN or the MODBUS protocol?

It uses DWIN 5AA5 protocol and I communicate with screen through UART.

Your two screens are T5L series and cannot read the device ID
