Ok, u do have a point and that must be the issue here.. BUT..
could it be so that the LCDout-command is causing this RMW behaviour and not the other way around?
I mean without LCDout everything works fine.. o:-)
what can I do about that build-in LCDout-command?
I don't have time and energy to write my own LCDout-command..
o:-)
