Our small team is developing an open-sourced visual language for microcontrollers for about a year. It’s called XOD. We decided to focus on Arduino platform from the start but it doesn’t locked on any vendor. And now the alfa version is comming.
So, we are looking for the first testers to provide them with private access.
Here is some more details about XOD: xod.io
The main feature of XOD in compare with other visual languages - XOD generates native code for controllers (including Arduino), so no firmata, no controlling PC needed.
Looking for enthusiasts =)
