-*****************************************************************************
-** ChibiOS/RT port for Atmel AVR ATmega2560.                               **
-*****************************************************************************
-
-** TARGET **
-
-The demo runs on an Arduino Mega2560 board.
-
-** The Demo **
-
-The demo currently just prints the number of External Interruption detected
-on the Serial0, which is available on the board USB connector
-(FT232 converter). The LED on PB7 (pin 13 on Arduino IDE) is also toggle on
-every interruption. A switch is connected to INT4, the D2 pin on the Arduino
-Mega2560 board.
-
-** Build Procedure **
-
-The demo was built using the GCC AVR toolchain.
