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. See: http://blogs.yahoo.co.jp/jf1vrr_station/19783647.html (Japanese)
