Hullo all!
I run a bioengineering research group in animal locomotion and we're having loads of fun building kit with the teensy 3.1 -- mostly using it do drive high speed video camera frame grabs and synchronize other digital triggers. We're at www.spencelab.com
But i'm increasingly frustrating with having to use LabView on Windows for data acquisition: i would love a solution for data acquisition i can run under Ubuntu. And cheap is always good. No GUI or a simple tk interface with Matplotlib graphics (e.g. written in Python) would be great.
I'm wondering, could you make a data acquisition system with the teensy 3.1 that does, at minimum, one analog input at at least 100 kS/s, and one analog output at at least 100 kS/s, over the USB? Great if it could just be done on the teensy; but an external ADC and DAC are certainly an option if needed, as would be FIFO memory; but at this point if you are creeping up towards $300 or $500 it could be time to just get a comedilib compatible data acq NI PCI board, or another vendor's Linux compatible data acq board.
But the fast USB and power of the teensy made me think it might not be crazy to think about using one to do high speed DAQ.
Thanks for your time and input!
