That's fine, but it's of little help to an uninitiated amateur -- one needs at least a circuit diagram.......
If it will be of use, no problem.
I have a circuit diagram and board layout, I can also write some notes and add code snippets,
but I would not suggest that an uninitiated amateur try this except as a last resort.
I'll put it all together over the next few days and try to find somewhere to post it.
