Could you provide the name of the LCD Display used with the Helix Display Interface? I am struggling to find one with the correct pin layout.

Hi @TnnsBeast that is just a regular 16x2 LCD display with the Hitachi driver. The pinout layout is not the most common one but that's the only thing I had laying around. You can find the pinout in the schematics

And the display is something similar to this, at least the pinout is the same https://www.digikey.com/en/products/detail/newhaven-display-intl/NHD-0216BZ-FL-YBW/1701195. https://newhavendisplay.com/content/specs/NHD-0216BZ-FL-YBW.pdf

The easiest thing you can do is probably build an adapter between the two pin layouts, they are exactly the same except for the arrangement. I just found the schematics here: https://www.cpmspectrepi.uk/raspberry_pi/MoinMoinExport/VariousDisplays.html image
