[Question] Trigger Variable Data input by Serial Terminal

MartinDuarte

Hello, I want to show 2 numbers in a text box "Data variable" using "Return key code". If the case would be 1 digit, it's ok because the previous number gets overwritten. I verified in DWIN debbuger.So, correct me if I am wrong, in case of more than 1 digit it must be implemented with "Variable input" button, isn't it?
How's the way to trigger this button, without being touched?
I mean, how can I send over Serial Terminal this action?
Is there any example of this? PDF; Images...

I give my example:
Variable data input : (Xs, Ys ) (Xe,Ye)  => (0,0) (30,30)
PIC_ID = 0x00 0x00
PIC_NEX = 0xFF 0xFF
PIC_ON  = 0x00 0x00
TP_CODE = 0xFE00
VP = 0x20 0x00

How can I arrange previous data in Serial frame?

Any "serial frame" or graphic example will be appreciated.

Hello, you have to realize this problem through C51 program.

Each "Data ariable"box can only store and show 1  data( 2-digit number,tens' digit,or hundreds' digit,etc).
Yes,the"Variable input"can input data into the "Data ariable"box,also,u can just send Communication command through the Serial Terminal
for example:
Dwin Standard communication protocol command: 5A A5 05 82 1000 0002
5A A5  start of frame
05       length of frame
82       data write(if it is 83,that means read )
1000   VP
0002   data (in hexadecimal)

As you can see,the "return key code"has its value that can be set,the Working principle is : once the "return key code"botton is clicked,
the value u have set will put into the VP,then clear it .You can just input data into the VP of the "return key code"by the command just mentioned,
sending in the data equal to the value, in that case,you can trigger the "return key code" without touching it.

Thank you for your kindy reponse Dora and 帅到爆 .

Hello, you have to realize this problem through C51 program.

It would take more time, I know that loading C51 program overwrites 8283 native DWIN protocol, so I can't use it anymore.

I still think that I didn't express myself correctly.
Suppose I've already done my entire GUI program, and placed Data input variable with these data:

I give my example:
Variable data input : (Xs, Ys ) (Xe,Ye)  => (0,0) (30,30)
PIC_ID = 0x00 0x00
PIC_NEX = 0xFF 0xFF
PIC_ON  = 0x00 0x00
TP_CODE = 0xFE00
VP = 0x20 0x00

How can I use Serial Commands to trigger Data variable input? Is is possible? I mean, the action of touching Variable-Input-Button but through Serial Communication - Terminal. I leave some image caps of DWIN Application development guide.

The analog touch variable 00d4 can trigger the touch effect without clicking on the screen. Follow up the coordinate position to simulate touch control. See the screenshot for the specific use method.
