guten tag, ich bins wieder
ich hab ein problem mit meinem momentanen programm...
als "vorlage" habe mir das "testprogramm" für dieses board
heruntergeladen
da ich aber dieses ganze serverzeug nicht brauche, habe ich mir das für
mich wichtigste herauskopiert...
Hier mein momentanes programm^^

hier gehn die tastenbelegungen, also das relai, der buzzer und ein
signal auf port6
aber display is hier noch nicht beschrieben
wenn ich dann (WDTCTL = WDTPW + WDTHOLD; //Watchdog aus) im programm
weiter nach vorne gebe, um genau zu sein direkt unter die
Portinitialisierung, dann ist das display beschrieben, die
tastebelegungen funktionieren jedoch nicht mehr...
also entweder display oder taster^^
blick da nicht mehr durch
wisst ihr da weiter?!
