biopac networking
I'm trying to modify the code in the reference manual to import biopac data channels into a common data file that Vizard records.
The first problem is that Vizard running on computer1 doesn't recognize the AcqKnowledge software running on the networked computer2 (I get an error that there's no module named acqserver). When I try to 'manually' connect to computer2 from the Vizard computer: Code:
viznet.client.connect('192.168.10.1') I appreciate any suggestions. Code:
# test to write biopac data to file import viz import viznet if viznet.client.connect('192.168.10.6'): print 'Connected' viz.addNetwork('192.168.10.6') viznet.server.start(port_in=9999) import acqserver viz.go() ###### NETORK SETUP ####### acqServer = None useAcqServer = False ###### NETORK SETUP ####### def useAcqServer(): # setup network connection global acqServer, useAcqServer try: acqServer = acqServer.ACQServer() acqServerList = acqServer.findAcqKnowledgeServer() if not len(acqServerList): useAcqServer = False return # set ip and port (ip,port) = acqServerList[0] acqServer.setAcknowledgeServerInfo(ip,port) #work around for acqserver problems acqServer.changeDataConnectionMethod("multiple") acqServer.changeTransportType("udp") acqServer.changeMostRecentSampleValueDeliveryEnabled("calc",0,True) except Exception: useAcqServer = False return useAcqServer = True ################################# MAIN CODE ################################# useAcqServer() ################################# END MAIN CODE ############################# ################################# Callback functions ######################## def onKeyDown(key): print acqServer.getMostRecentSampleValue("calc",0) # Print the incoming data point print "Z(t) Raw: " , acqServer.getMostRecentSampleValue("calc",1) print "ECG: " , acqServer.getMostRecentSampleValue("calc",2) print "Blood Pressure: " , acqServer.getMostRecentSampleValue("calc",4) print "dZ/dt: " , acqServer.getMostRecentSampleValue("calc", 41) viz.callback(viz.KEYDOWN_EVENT,onKeyDown) |
