RADDS (Due) with RADDS 20x4 display not working on 1.02

I have a RADDS board that I have used in the past and was working with .92 but I needed to reconfigure it for CNC use but for some reason all I get are two rows of blocks with v1. I have tried everything, even a shorter cable and added initialization delays. The encoder seems to be working because I can hear it click, just no display / menus. Anyone else have this happen before? Was anything changed in v1 like timing that I can look at?


  • Stupid me, it has been awhile since I used this board and I remembered that I rewired the RADDS LCD to use different pin groupings to cut down on signal noise so the cable can be longer. I finally remembered and found my old configuration.
