well, with the firmware V1, we have two free GPIO pins, and one of these is for a PIR, so in reality it does not matter very much if you make it from the basis of V1 or V2 firmware. In the next few days I intend to also put the PIR code into the V1 4 digit, and that will work with all clock versions.
Hi Ian, sorry you feel this way, and posting someone's name on the internet before contacting but the all in one pcb was designed by a colleague of mine, I ordered a couple and sold them non profit to my colleagues. I had a couple left and sold them. Same goes for the modular. I looked up the definition open source and fork and came up with:
Free and open-source software is that which, by definition, may be forked from the original development team without prior permission
If you were interested you would have found that the license is CC-BY-NC, that means that you are not allowed to take it for commercial purposes. I'm not going to get involved in arguing about what open source means.
I'm also not going to get involved with discussing with you if the hardware or software is different. It's close enough that I can help your customer without any detailed information.
You are also required by the license to publish your source code, so please do that, so we can all judge how derivative your code is.
You have just admitted responsibiltiy for what has happened. How or why it happened is irrelevant. Relevant is only the fact that you did it, and have admitted responsibility for it.
