Synchronized Acquisition

[bhclowers]

This is surely an interesting project and it will surely serve as a learning experience. Two questions that come to mind are:

1.) Based upon the examples shown there appears to be some variability in the data acquisition rate. Is this correct or just the transfer speed? What I'm getting at is how to accuractly assign spacing between the points?

2.) Is there a way, from your perspective, to synchronize the data acquisition with an external trigger or is this best accomplished using multiple input channels on the Teensy and then align through post-processing?

Cheers

1. I have mostly fixed the jitter issue, previously there was a lot of variability in the data acquisition rate.
2. You could use a Teensy interrupt to trigger the data acquisition start/stop, this would be pretty closely synced.
