I think I put in Uint16 not UInt16 yesterday when I tried this. I fixed it and it compiled but same result.

I put some print commands in so I can see what commands are being executed.

The results of running this is

Main listener rospy.subscriber() when I Ctrl-C it shows rospy.spin()

Looks like the callback function isn't being called.

#!/usr/bin/env python
import roslib; roslib.load_manifest('sensorcsv')
import rospy

from std_msgs.msg import UInt16
def callback(data):
    print "Callback"
    rospy.loginfo(rospy.get_name()+"I heard %s",data.data)
    print rospy.get_name()+"I heard %s"+data.data

def listener():
    print "listener"
    rospy.init_node('listener', anonymous=True)
    rospy.Subscriber("Adc", UInt16, callback)
    rospy.spin()
    print "rospy.spin()"

if __name__ == '__main__':
    print "Main"
    listener()
