Added support for HC-SR04

ks156 commented 9 years ago

Added a function in IoTPy
Added the support in weioLib (weioIO.py and weioGpio.py). Usage :

HCSR04Read(trigger_pin, echo_pin)

New version of the firmware that support this sensor
Changed the DHTxx SFP id from 200 to 100 to leave some room for other devices

Example code:

from weioLib.weio import *

def setup():
    attach.process(myProcess)

def myProcess():
    while True:
        print HCSR04Read(0, 1) # trigger pin, echo pin
        delay(200)

This function return the distance in centimeters.
