BioPac - acquisition problems
Hi,
I'm using BIOPAC's MP150 system to acquire some physiological data. To do this I'm using some methods from "acqserver.py ". On one of the acquisitions (That includes 6 channels - 2 analog and 4 calculated) I'm reading one of the clculated channel using this command : bpm = myAcqServer.getMostRecentSampleValue("calc",0). It works just fine. When trying to apply the same method to another acquisition (2 analog channels solely), changing the channel type and ID to this method : bpm = myAcqServer.getMostRecentSampleValue("analog",13) I'm getting an exception : " raise ACQServerException(str(exobject)) acqserver.ACQServerException: <Fault 0: 'Unable to get most recent value for channel'>". In both tries the acquisitions itself (on another computer LAN connected) runs smoothly. Any idea how should I start troubleshooting? Thanks! Ohad |

Forgot to mention (as this should be the first thing to check) -
before using : bpm = myAcqServer.getMostRecentSampleValue("analog",13) I remembered to enable the channel with : "myAcqServer.changeMostRecentSampleValueDeliveryEn abled("analog",13,True) Any other idea? Thanks again, Ohad |
