Python Arduino Prototyping API v2

This is a project based on the original Python Arduino Prototyping API. I started a fork and after a while the whole thing was getting too different to make a pull request so I just put it here. The old project had wierd things going on to handle the communication, where I rely on parseInt() to do the work for me. There were also problems with analogWrite(), which is working in this version.

Major changes:

.pde is completely redone
Small changes in the arduino.py file
Added examples

Here follows the original README (with updated example):

The Python Arduino Prototyping API helps you to quickly prototype Arduino programs, without having to repeatedly load the program to the Arduino board.

Setup:

Load prototype.pde onto your Arduino dev board.
Import the arduino lib in your python script.

Methods

Arduino.output(list_of_output_pins) - set the output pins

Digital I/O

Arduino.setHigh(pin_number)
Arduino.setLow(pin_number)
Arduino.getState(pin_number)
Arduino.getState() - returns true if pin state is high, else it returns false.

Analog I/O

Arduino.analogRead(pin_number) - returns the analog value
Arduino.analogWrite(pin_number, value) - sets the analog value

Misc

1.) Arduino.turnOff() - sets all the pins to low state

2.) Arduino.close() - closes serial connection. Using this makes sure that you won't have to disconnect & reconnect the Arduino again to recover the serial port.

Usage example

from arduino import Arduino
import time

b = Arduino('/dev/ttyUSB0')
pin = 9

#declare output pins as a list/tuple
b.output([pin])

for xrange(10):
    b.setHigh(pin)
    time.sleep(1)
    print b.getState(pin)
    b.setLow(pin)
    print b.getState(pin)
    time.sleep(1)

b.close()
