    Touch screen advice

    I am looking for a touchscreen and a bluetooth solution to build a touchpad/controller

    Has anyone used the nextion screens ?

    Ideally a screen and enclosure solution

    Any suggestions greatly appreciated

    I have used the Nextion in the past, i used the 7 inch model with capacitive touch.

    1) I was not pleased with the editor, strange issues, sporadic loss of elements on the screen.
    2) The fonts look really bad, ugly spacing between char's, no antialising.

    @gadget999 - Not me,

    Might help to have an idea of which type ones you are looking at, I see some from banggood for maybe $21 and others from $200-$300 which are probably very different.

    I use the heck out of the 2.4" and 2.8" inch TFT's (ILI9341) and HX8357 (3.5 inch units). I use all aspects such as graphics, SD usage and touch. I wish there were larger more affordable units. I use a combimation of adafruit buttons, my own libs, pauls font libs, etc. Not sure how i can help other than i've had very good luck with these units

    Here are 2 examples of what I use these displays for

    Again not sure what all your requirements are. As mentioned we have done a lot of work on the ili9341 library and touch screen that PJRC sells.

    Also recently some of us have done some work on making sure the RA8875 displays work on the T3.x and T4...
    As you can see in the thread: https://forum.pjrc.com/threads/57280...rom-Buydisplay

    The 3D printer I use is a makerbot we have at work. There are several online printing services that are very affordable. The software I use is Solid Edge and you can get a free download (student edition) at https://www.plm.automation.siemens.c...ftware/student. Disclaimer I work at the company that develops this software.

    that looks like the same ones I use. drawing buttons is more dependent on the library and not the display. The library used is ili9341_t3. optimized for the teensy and supports Adafruit_GFX operations. Buttons are part of that lib. Using this lib I can create graphics, buttons, sliders, etc. jsut like what I show in my vids. I've also found a display that supports the getPixel function and I found a screen capture utility that will take a snapshot of the screen and save the image to an sd card.
