      Hi,
      is there any chance to get the other types of 12864 displays working with a Maestro?
      It would be so nice to be able to use the MKS Mini LCD or the type made/sold by FYSETC.
      If Marlin and Klipper (also with a Maestro) can do that, Reprap should always be able 😉

        Any 12864 LCD that uses a ST7920 chip should be usable with the Maestro. Unfortunately, some of them have different pinouts, so you may need to use a different cable.

          MKS Mini LCD or the type made/sold by FYSETC

          both seem to use UC1701 or ST7567

          It works configuration wise like the ST920 in controller 11 but you need to define U8GLIB_MINI12864_2X_SW_SPI instead to use that driver.

            The ST7567 needs an additional pin to control it, which the Maestro does not provide on the 12864 display connector. So you would need to connect it separately to one of the expansion pins, Also the chip expects this to have a 5V signal level (minimum input high logic level when run from a 5V supply is 3.5V). So for reliable operation you would need to level-shift this signal from 3.3V to 5V too.

            I am not familiar with the UC1701.

              Thank you for the information.

              Do you know less "bulky" LCDs than the typical reprapdiscount type?

                The bigtreetech tft24 works with maestro in it's 12864 simulation mode. See my recent post in My Duet Controlled Machine for an example.

                The creality minipanel also works, but lacks a physical reset button. It just needs the cable turned 180 degrees. The Duet wiki covers setting it up in the ender 3 conversion guide.

                  I'm sorry, I am not familiar with all the different 12864 displays on the market. We chose to support the RepRapDiscount because it has been widely cloned and is in widespread use.

                  When we revise the design of the Maestro, we'll look at providing another level-shifted output so we can support these other types of 12864 display.
