RepRapdiscount full graphics smart controller won't work in Repetier
I built an adapter for my Melzi board so I could use the RepRapdiscount graphics smart controller with Repetier firmware but I can't get it to compile without an error about dio49. It works ok with Marlin firmware flashed but I can't get all the parameters correct in Marlin. I tried to change the eeprom parameters in Repetier-host but all I get is a blank window. What am I doing wrong?
