  • uLCD-70DT-AR Head-Up-Display

    Dear all,

    im currently working on an Arduino-Project, where I want to display some Values via the uLCD, but as a Head-Up-Display. Therefore I need to flip/mirror all the values. I´m currently working with the Visi-Genie.

    Is there any chance to do such operations on the screen?

    Many Thanks

    Hi Jonas,

    Welcome to the forum!

    If you're using ViSi Genie on the free version of the Workshop4 IDE, I'm not sure if there is a way to do this other than to generate customized images that looked flipped.

    To describe this in more detail, if you want a flipped gauge, you can create a GIF of a flipped gauge and store it in a video or User image widget.

    You can then write to that widget as you would with a regular gauge.

    Another suggestion would be to use ViSi instead. In ViSi, you may use this snippet to mirror/flip your display.

    disp_WriteControl(SSD1963_SET_ADDRESS_MODE);  // write a control byte to the display
    disp_WriteWord(0x000A);     // write a word to the display
    In my case, disp_WriteWord(0x0009) flips the display vertically and disp_WriteWord(0x000A) flips the display horizontally.

    You may find more information about this on the Diablo16 Internal functions Reference Manual.

    The uLCD-70DT uses the SSD1963 LCD Display Controller, you may also check its datasheet for further reference.


    This is also achievable with ViSi-Genie through the use of Magic codes, however, that would require a PRO License.

    If you are interested in using Magic Codes, this application Note might be helpful.

    I hope this was helpful.

      Hi Michael,

      many thanks for the answer! I purchased the PRO-Licence and inserted the Magic-Code, it works perfect!
      Best regards
