      Does your screen support the display of QR codes, and if so, what do i need to do?

      Hi Cliffhanger
      This control converts a piece of text into a 2D code that can be displayed on the serial port. After writing the text corresponding to the 2D code into the variable address unit with the 0x82 instruction, the serial screen will generate the code according to the written text and display it at the specified position.
      When the text is less than or equal to 154 bytes, the size of the code is 45×45 cells; when the text is greater than 154 bytes, the size of the code is 73×73 cells. The actual number of physical pixels per cell is defined by Unit_Pixels in Figure 4-3-8.
      The screen will generate a QR code based on the written text and display it at the specified location.

      Could you please advise if you are doing an update of the dynamic QR code?
