README
|
||||
^^^^^
|
||||
|
||||
This is the README file for the port of NuttX to the Arduino Mega 2560 Rev3.
|
||||
|
||||
https://www.arduino.cc/en/Main/ArduinoBoardMega2560
|
||||
|
||||
The board is based on ATMega2560 chip from Atmel
|
||||
|
||||
http://www.atmel.com/devices/atmega2560.aspx
|
||||
|
||||
|
||||
Toolchain
|
||||
^^^^^^^^^
|
||||
|
||||
Right now only Atmel's AVR8 Toolchain is supported. You can get it from
|
||||
|
||||
http://www.atmel.com/tools/atmelavrtoolchainforwindows.aspx
|
||||
|
||||
It is basically WinAVR compatible so sub-projects may define WinAVR as a
|
||||
tool-chain but specify path to the Atmel AVR8 in path. See
|
||||
arduino-mega2560/hello for example.
