Python on a chip on Arduino Mega
1. Install tools:
- A. Cygwin
- http://www.cygwin.com/
- Remember to select GCC and python packages.
- http://cygwin.com/faq.html
- B. Install WinAVR:
- C. Download PyMite 8 http://www.pythononachip.org:... 150px
2. Download our arduino mega port and place under trunk$\src\platform
3. Under trunk$, do
- make PLATFORM=arduinomega
- If it shows pmfeatures.h is missing, please check that you are using the make from WinAVR. Correct the PATH to make sure you are using that make.
- The following is the command to check:
$ make --version

This program built for i386-pc-mingw32
4. The next step is to program the generated main.hex to the Arduino mega board.
- You need STK500, and install AVR studio. Choose Device type ATMEGA1280, and fuse setting is shown as...300px
5. Find a serial port and see what comes out from the serial port of Arduino Mega:300px
The following is main.py, the Python script that got running:

print "Expect a NameError (0xEA) after this."
