There is no problem with giving you the firmware code, I don't mind. But I just wanted to release the first version of the firmware (with code) when it will be fully functional (now it has some trouble with communication and I wasn't working on it for more than month).
Now I don't know what to do - should I give you that non (fully) working code or release the functional version, when I'll finish it.
I don't even mind if you would make any/lots of profit from this interface - it's a hobby for me, not a job.
