+*****************************************************************************
+** ChibiOS/RT and NIL PWM demos for Atmel AVR ATmega1280.                  **
+*****************************************************************************
+
+** TARGET **
+
+The demo runs on an Arduino Mega board.
+
+** The Demo **
+
+This demo creates three PWM channels on pins PB5, PB6 and PB7. Each channel uses
+a different duty cycle with PB7 having a duty cycle of 50%, PB6 a duty cycle of
+25% and PB5 a duty cycle of 75%. Since the LED is connected to PB7 on the Arduino
+Mega, it can be seen flashing in high speed.
+
+** Build Procedure **
+
+The demo was built using the GCC AVR toolchain.
+To build linking with ChibiOS:
+
+$ make -f Makefile.ch
+
+To build linking with NIL:
+
+$ make -f Makefile.nil
+
+** Notes **
+
+This demo runs natively so the Arduino bootloader must be removed and the FUSEs
+reprogrammed. The values used for fuses are LFUSE=0xe7 and HFUSE=0x99.
