Great Question Bhouston.. 

I would recommend getting it working in MRL - then getting it to work in InMoov

Assuming you have the latest MRL...

Try the following script ..

 

sr04 = Runtime.start("sr04", "UltrasonicSensor")

 

# there are 2 ways to get range data

# 1 is a blocking call - the other is event driven

# we are going to use even driven because it's preferrable

 

# tell the sr04 range finder to send its range to python

sr04.addPublishRangeListener(python)

 

# here is the "callback" 

def publishRange(distance):

  print distance

 

# attach the sr04 to the Arduino and connect MRL to the

# Arduino - input is (input port, trigger pin, echo pin) - 

# but it sounds as if the trigger and echo pin are tied together ?

# sr04.attach("COM4", 8, 7)

 

# try this way trigger & echo pin the same

sr04.attach("COM4", 7, 7)

 

# start the process of ranging

sr04.startRanging()

 

# get a bunch of ranges and print them in the publishRange function

# for 10 seconds

sleep(10)

 

# done

sr04.stopRanging()
