I was using the auxiliary voltage channel set to 100mV range, 125Hz, sample rate, I think a buffer depth of 4.
However I did some things manually that you don’t have access to in the app yet – you’ll notice that if you try to use those settings in graph mode, it will be quite hard to keep the graph zoomed in because the voltage will drift and the graph will scale to accommodate it. For that demo video I modified the source code of the app to keep the graph zoomed in, and added a derivative filter to make the differences between subsequent readings more clear. Both of these are on the “to do” list for the apps, so stay tuned to the updates. First on the priority list is providing support for the users who are hitting compatibility issues.
Thanks, let me know if you have more questions!
