[Question]How to change my page by the serial command ?

jhpark

Hi, I'm trying to change my page to another one by the serial command,
and tried a few ways to change my page

Before asking about my trouble, as far as I know, I think 'page' is the number of 'location' value on DGUS2,
is it correct ? I need to change my location 0 to another like 1, 2, 3....

First trial was announced at the document, T5L_DGUSII-Application-Development-Guide-V2.5.pdf.

    5.1 System Variable Interface
    System variable address range: 0x0000-0x0FFF.

        0x84 PIC_Set R/W 2
        D3: 0x5A = enable page operation once, The CPU is clearedafter
        processing. D2: Processing Mode. 0x01=page switch (Display the image specified in the image storageareatothe current background page). 0x02=This mode is reserved and not supported.
        Instruction example:
        5A A5 07 82 0084 5A01 0001, display the 01 serial number pictureunderthe background picture ICL file (if the serial number pictureIDof thesentinstruction does not exist, the instruction operation judgment will not takeeffect.)

I tried to send : 5A A5 07 82 0084 5A01 0001
And nothing changed in my screen. It's still on the 0 page. '0002' and '0003' also are no way..

So, I tried to find another way and found a library.

https://github.com/dwinhmi/DWIN_DGUS_HMI/blob/master/src/DWIN.cpp

// Change Page

1. void DWIN::setPage(byte page){
   
2.     //5A A5 07 82 00 84 5a 01 00 02
   
3.     byte sendBuffer[] = {CMD_HEAD1, CMD_HEAD2, 0x07, CMD_WRITE, 0x00, 0x84, 0x5A, 0x01, 0x00, page};
   
4.     _dwinSerial->write(sendBuffer, sizeof(sendBuffer));
   
5.     readDWIN();
   
6. }

复制代码

It's same one with the document. So I guess above my first trial should be work as expected even it's failed..


But, I found another method on Youtube.

DWIN K600+ Tutorial: Directly change page or via command---from DWIN Technology

    5a a5 04 80 03 0001

I tried to send "5a a5 04 80 03 0001" but nothing changed in this time too.


Could you let me know how to change my page to another ?

Dear, what is your complete screen model?
5A A5 07 82 0084 5A01 0001 this command for page switching is suitable for T5L
5a a5 04 80 03 0001 this command for page switching is suitable for K600+

Ah, K600+ has different type of commands. I see !
I have "DMG10600F101_01WTC"
and I thought "5A A5 07 82 0084 5A01 0001" should be work but it wouldn't.
So I'm tryin to find why and new way to do...

You can check whether the communication of the screen is normal, send 5AA5 04 83 000F 01 to see if there is a return, if there is a return, the communication is normal, and the page cutting instruction (5AA5 07 82 0084 5A01 0001) can cut the page normally.
