I don't know why, but my pin 12 does not work well.Using another digital pin all works very well.
but my pin 12 does not work well.
PLEASE NOTE THAT ON THE LCD'S DB0,1,2 MUST BE CONNECTED TO GROUND AND DB3 TO VDD.BY THIS WAY THE LCD IS PROPERLY SETTED TO 4 BIT 2 ROWS.LET DB0,1,2,3 DISCONNETED DOES NOT ALLOW PROPER INIZIALIZATION
