+** ChibiOS/RT port for Atmel AVR ATmega1280. **
+*****************************************************************************
+
+** TARGET **
+
+The demo runs on an Arduino Mega board.
+
+** The Demo **
+
+This demo uses ICP3 (ICU3 input) which is located on pin PE7 to measure signal
+width and period. The signal is output on pin PD4 using standard PAL calls and
+thread sleep functions. PD4 must be wired to PE7. It outputs three different
+waveforms with aproximately 1s duration using 50%, 25% and 75% respective duty
+cycles. After that it just turns on ICU3 and waits for it to overflow. The values
+read on each of these operations is output to SERIAL1.
+
+** Build Procedure **
+
+The demo was built using the GCC AVR toolchain. It should build with WinAVR too!
+
+** 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.
