1*****************************************************************************
2** ChibiOS/NIL port for Atmel AVR ATmega2560. **
3*****************************************************************************
4
5** TARGET **
6
7The demo runs on an Arduino Mega board.
8
9** The Demo **
10
11One thread prints a message to the serial console, which is available on
12the board USB connector (FT232 converter).
13
14Another thread toggles the LED on PB7 (pin 13 on Arduino IDE) every 500ms.
15
16** Build Procedure **
17
18The demo was built using the GCC AVR toolchain. It should build with WinAVR too!
19
20** Notes **
21
22This demo runs natively so the Arduino bootloader must be removed and the FUSEs
23reprogrammed. The values used for fuses are LFUSE=0xe7 and HFUSE=0x99.
