*****************************************************************************
** 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.
