Hi, Mounted a Midas LCD on my MB6582 and I remember that I encountered the same problem... I first made the "standard" wiring and burned the backlight... Figured it out (after having bought a second LCD :/ ) by simply following this little scheme in the spec : ... and made some rewiring around P2 trimmer : Finally, check the wiring on LCD side. Pins 15 and 16 should be inverted, but double check with the LCD pinout. Hope that will help you. Cheers!

Hm, I vaguely recall being confused by the pin numbering as well. In any case, the guide you linked to should be correct, as J15 has the same pinout on MB6582 as it does on a normal core (where the pins aren’t labeled, fwiw).

The LCD wont show anything (except maybe a series of squares where the characters are supposed to be) without the PIC. Or did you mean that the backlight wont turn on? I would just go ahead and burn the PICs. You will be able to tell if it worked when you connect to mios on your PC via MIDI.
