Hi Charlie thanks you so much for your help. Got the schematic and wired the keypad accordingly with pins 22? to 27. Still no joy, the LCD? shows the splash screen and then to feed but the keypad doesn't work.? I am wondering if the? schematic is applicable for Version 5 ? Anyway I can revert to V2 and as said before works OK but I have to refigure the keypad back . Meanwhile best regards
