Labview not updating gui


of Physical Medicine and Rehabilitation, Bioengineering, University of Pittsburgh Developing BCIs is an active research area for direct communication between the brain and external devices.This communication pathway could greatly benefit people with physical or neurological disabilities by helping them control assistive devices such as computers, wheelchairs, and prosthetics.Developing BCI software can be quite time-consuming, which prevents researchers from investing time in developing new algorithms and investigating the scientific problems related to BCI technology.Craniux is a software suite developed to give researchers an extendable, modular framework for BCI research using Lab VIEW system design software.While the other two engines execute in parallel, the engine sends data to the data saving manager and synchronizes itself with its GUI before waiting on data again.Craniux's performance was first validated with simulated data sent from an NI PCI-6723 static and waveform analog output device through two NI SCB-68 blocks. USBamp amplifiers and processed in 40 sample (33.3 ms) blocks.In parallel, these packets are dequeued and sent to the stand-alone data saving manager, which streams the data to a file using the Lab VIEW TDMS format.



The Solution: Using the powerful visualization and processing tools provided by NI Lab VIEW software to create a modular framework capable of real-time operation that allows the user to distribute components across a network and interchange them during run time.
