-// Function
-//      5 channeles ADC data records into a file which is located in SD-Card
-//      If USE_LCD = 1, data shows on a Text LCD
-//      If USE_RTC = 1, time stamp also writes in the file
-// Connection
-//      Analog input    PIN 15,16,17,19,20
-//      LCD             PIN 22,21,8,7,6,5
-//       -> CAUTION!! pin assignment is different
-//          with " http://mbed.org/projects/cookbook/wiki/TextLCD "
-//      RTC             PIN 3 needs to connect 3V Battery
-//       -> Please refer my program " RTC_w_COM" for time adjustment
-//          at " http://mbed.org/users/kenjiArai/programs/RTC_w_COM/5yi9a/ "
