Hi, I made a wireless oximeter (wireless sensor to hardware) with a pic16f877 with connection USB (hardware to PC)and I would like to know how can I use the LabVIEW to show the wave, digital saturation of SpO2 and heart beat?
Since it is your own device and would be familiar with the USB-RAW protocol for it, you could use the VISA Driver Development Wizard as detailed at http://zone.ni.com/devzone/conceptd.nsf/webmain/6792bab18242082786256dd7006b6416?OpenDocument. If you have created any other type of software (i.e. dll or ActiveX) to communicate with the device, you could use the Call Library Function Node or the ActiveX functions in LabVIEW.
