SSVEP qwerty speller

Hi,
I searched this and other forums in order to find some open-source ssvep keyboard that I could use for creating a working speller with my openBCI setup. Unfortunately, I did not find anything that could work, almost all of the research papers do not share the software that was used and the speller I have found on github work only with specific hardware. Is anyone in here familiar with something that I could use with my OpenBCi hardware and data preprocessing + feature extraction done by myself?
Best regards

Matthew, hi.
The following is not SSVEP, but it is much better, called cVEP (code based). Many times easier and faster to operate (for the subject) than SSVEP. An SSVEP speller would require a multi-layer choice tree, not a full typewriter keyboard (any letter/number can be chosen from top level).

They originally did a Kickstarter for a closed source version, running on a Raspberry Pi. But they announced later they are open sourcing the entire software. So it's probably at the Github above. Also see,

PS there is a recent post on the Community site, with an SSVEP system, but it uses the choice tree approach,
