MrDEB , how about trying to make all the needed changes & corrections to your schematics before posting them, rather than adding some and apparently saving others for later? Once again, you have so many different versions posted ain't nobody can keep track of what's what, including you.
In post #45, the latch circuit is drawn correctly.
In post #50, you screwed up the latch circuit. In post #54, I pointed that out. Yet your latest schematic hasn't corrected that error.
In post #52,
Pommie pointed out the wiring error on your switches. Not corrected in your latest schematic.
I also suggested adding a two pin header to bypass the latch circuit during programming and dev, which hasn't been implemented or acknowledged. If you don't understand something, rather than blowing it off, ask why it's important.
Yes, you have made some of the suggested changes (ICSP V+ connection and LCD control lines). Do you expect a gold star for doing so?
I don't mean to be harsh, but I just spent an hour comparing schematics to figure out what changes have been made, fixed or broken. It would be useful to say exactly what you've changed in each schematic. You'll keep track and commenters will know w/o searching.
