+/* This program outputs the voltage to a DA converter 
+and inputs it into AD converter and displays it to LCD. 
+The voltage changes it to 3.3V by a 0.033 volts step 
+from 0 volts and displays it every 0.5 seconds. 
+DA port is p18. AD port is p20. It is necessary to 
+short-circuit with a wire in p18 and p20 before 
+executing a program. The voltage that output to a 
+DA converter is displayed by the first line of the LCD. 
+The voltage that read with AD converter is displayed 
+by the second line of the LCD.
