Communicating between LabVIEW and Propeller

jime

I am trying to communicate between LabVIEW 2012 and a propeller Quickstart board using 'Exchange Int32 Values with Propeller.vi' and 'Exchange Long Values with LabVIEW.spin'. I am using the default setup values. I keep getting Lab VIEW ERROR 74. I have tried turning off the READ switch before startup and then turning it on after startup as suggested in another discussion, but I continue to get the error. Any suggestions?

Hope you can figure this out. I think that READ switch idea came from here:

I guess I'd double check those instructions. Maybe check the com port# is correct. Make sure the Prop is loaded with code in EEPROM in case it gets reset....

Can you step those VIs?

Thanks Rayman

I loaded the Propeller software into EEPROM instead of RAM. Everything works like a charm.
