Hi there bowcoastie,
haven't checked this thread in a while so it's great to find a post here!. Yep, I've been watching the progress for the last couple of months and V7 sounds like a great improvement. Still fighting with Google translate to make sense of it all but I'm getting there. Haven't really done anymore since I downloaded V 6c and installed on the Mega. Had a bit of a play with switches and stepper connected, without much luck then got busy with harvest( I'm a farmer) and haven't really got back to it.
I would love a copy of your translated docs and commented code if I could. Started to do the same myself until harvest started. Nice to see that there are a couple of circuit board layouts now for the interface with the Arduino Mega, though I don't know why they are trying to fit everything on such small boards? Just make them 25-50% bigger and there's plenty of room for everything. Not really an electronics buff myself but if I have a board layout with component placement then I can get it done.
Anyway, great that there's someone else interested in this.
I think this is a great project and look forward to having a play again with it . ( though you might need to give me a bit of help
)
