Mark20

I just bought 4 pcs of DMG12720C050_03WT display and i can't find UART4 activation file for this display, this is the kernel version 5A A5 06 83 00 0F 01 41 10.
Please somebody help me to activate UART4.
Thank you

Hello,Mark20.
The default of this display is the DWIN protocol of UART2, and UART4 is the extended serial port. It is blank when it leaves the factory. You can use OS to define the protocol.
The attachment is the UART4 program written in the OS assembly of DWIN, and the baud rate is 115200. You can download the . bin file in the attachment to activate URAT4.

Hi
Thank you for help, UART4 works now, but now i have this problem, please see the picture
I have simple project. 10 buttons with return key function.
Pressing from 1 to 0 and sometimes getting double return code.
Looks like touch functionality is not working as we expected.
Is there any troubleshooting?



Thanks.

Hi, I just tested the return key code function on my screen, but only received one return code. Could you mind sending your project for checking?

Thank you for replay.
I damaged the .CFG on this display, and then i used the .CFG file from T5L factory demo_12720 demo code.
I thing maybe that's why this display is doing this.Please check the attachment for the dwin file.and when you using SSCOM touch the buttons little fast ( 7, 8, 9)

Hello,Mark20.
I also tested your project on my screen,but only received one return code as below.
I checked your project,and the variable address of return key function is 1012,1014,1016, but your serial port return code is 2012,2014,2016.It's a little strange.
