  • Which display to use for new RPi design?

    Hi there, if starting a new design for a Raspberry Pi (I'm using a zero) coding in Python, which display would be a good choice to use as I note some say "Not recommended for new design". In other words, what's the latest and greatest displays?

    Looking at a 3.2" or 4.0" display, not a primary display, but being able to program (or control) a GUI with Python. I like the look of the 4 options provided by the Workshop 4 IDE.

    Thanks!

    Hello Pat,

    Welcome to the forum.

    The best display's would be the gen4 displays which come in a choice of resistive or capacitive touch.

    https://www.4dsystems.com.au/product/gen4_uLCD_32D/
    https://www.4dsystems.com.au/product/gen4_uLCD_35D/
    https://www.4dsystems.com.au/product/gen4_uLCD_43D/

    All the above are suitable for new designs and can be controlled via your Pi Zero using serial and your python code.

    You will be able to use any of the programming environments. Designer and Visi allow to write the entire GUI code on the display and gives you the ability to write your own serial protocols to communicate with th Pi Zero. Visi has the drag & drop graphics ability.

    The 2 Serial environments have their own protocols with Visi-Genie being a very simple drag & drop GUI creation and then using the built in serial commands from your Pi Zero using your own python code.

    This is the link for the Visi-Genie reference manual

    And the Diablo internal functions manual for Designer & Visi

    We don't supply a 4" display but the gen4_uLCD_43D is just a little over 4" and worth a look.

    I hope this helps

    Best regards

      ok thanks. I notice there is another series specifically for the RPi, e.g. https://www.4dsystems.com.au/product/uLCD_35DT_PI/

      It has a library for RPi however looks like it is in C and not python.

        Hello Pat,

        Yes the above display's come with a useful adapter to connect to a RPi. The library is a C only library.

        Best regards

        Paul
