Python Code:- ============= # # # Arduino test for Python 1.4.x under WinUAE only, NOT classic AMIGAs. # This is an experimental idea only to test the Arduino Diecimila # development board under Python 1.4.x and WinUAE. # (It is assumed that the Python 1.4.x install is in the default drawers.) # NOTE:- This code also works to Python 2.0.x inside WinUAE. # This working idea is copyright, (C)2008, B.Walker, G0LCU. # Copy this '' file into the 'PYTHON:Lib/' drawer # and you will be ready to roll... ;-) # Press ~Ctrl C~ to QUIT, OR, set the input to maximum of 5V, i.e. 255. # # It is assumed that you have WinUAE 1.5.3 or greater installed and running a # minimum of EMULATED classic AMIGA OS 3.0x, 68EC020, 2MB RAM, HDD; that is emulating # a stock A1200HD and Workbench 3.0x. # It is assumed that the SER: device is set up in the AMIGA mode. # See here for the correct parameters:- # # It is assumed that you know how to allocate the Windows COMx: device to WinUAE. # It is assumed that you know how to connect and set up the USB Arduino Diecimila # board inside Windows, (32 bit installs)... # There may be other forgotten assumptions too, not listed here! # # To run type:- # >>> execfile("PYTHON:Lib/") # NOW issued as Public Domain, you may do with it as you please. # # IMPORTANT NOTE:- With a piece of simple home built hardware add-on this WILL work # on a classic AMIGA A1200 with a standard Serial Port also.
