ofxEmotiBit VS EmotiBit_Docs

Check out the latest release for EmotiBit Software!

We have created a shell script to leverage this functionality and "batch parse" multiple files in 1 go.

You may be referring to this issue we have been recently investigating. The oscilloscope does try to ping github/ofxEmotiBit to get the latest release available. We do this to inform the user if a more recent release is available for use.

While EmotiBit software, firmware and cases are open source, the EmotiBit hardware is still closed source and the design files are not available to public.

I created an issue in our github repository: https://github.com/EmotiBit/ofxEmotiBit/issues/189

Upgrade to the latest EmotiBit Oscilloscope. Version 1.7.1 and later use a combination of broadcast and moderated unicast messaging to detect advertising EmotiBits

Now you have a data stream to plot in your application. And you can do that through OSC or through the new UDP output channel available in the latest release.

Additionally, I created an issue in the repository to update the instruction to reflect install on 22.04. Feel free to add a comment on this thread relating to any issues you may be having.

Check out the release page for more details and information!

Users who want to customize their EmotiBits by attaching additional hardware can now refer the schematic available in our documentation to get more information about available GPIO options on the Feather!

Managed to solve by manually installing the firmware with the Arduino IDE following the instructions in this documentation: https://github.com/EmotiBit/EmotiBit_Docs/blob/master/Keep_emotibit_up_to_date.md

Also, please remember to use github issues to raise any concerns with the documentation as it helps us keep a short loop in document revisions.

I'd like to use EmotiBit in a project and I am struggling to get the LSL communication work. I found these minimal examples or marker tests (referred to by EmotiBit_Docs on github). I tested the demo (marker.py) and got no errors, but I no markers were sent either. Is there a significant modification that should made to the demo?

You can check out our documentation, which details steps to work with the EmotiBit data.

@u/Student_Unisa_08, you can find a list of data TypeTags for EmotiBit in the documention https://github.com/EmotiBit/EmotiBit_Docs/blob/master/Working_with_emotibit_data.md

A: Yes, you can drive one of the available digital output pins on the Feather with a small code change in the loop section of EmotiBit_stock_firmware.ino. Instructions to build EmotiBit firmware can be found in the documentation.
