While here is vvvv likers I hope this will be interesting to you.
Our small team is developing an open-sourced visual language for microcontrollers for about a year. It’s called XOD. The idea came from vvvv, as it’s quite popular, so why programming electronics couln’t be like making vvvv projects.
And now the alpha version of XOD is comming.
We are looking for the first testers to provide them with private access.
Looking for enthusiasts =)
