I'm sorry if it seemed like I was asking for your help. You've done quite a lot already.
This post was to hopefully help others who are in my situation, or convince those considering using ePaper for some project. I've made a number of similar posts, mostly in the Hubitat forum but some here as well. If I struggle with some device (usually the case) I try to summarize my findings to help those behind.
My Caution that there may be some mistakes was just that. It was not a cry for someone to correct those mistakes.
I will admit I was kinda asking for help with the different buffers, however I don't expect you to spend time teaching me. I will, once I get them figured out create a similar post on what I find hoping to pass on the knowledge I've found.
So I'm sorry if I made it feel like I was badgering you for information 
I only included your forum name because I was uncomfortable posting this code without folks understanding there was absolutely no unique code from me and all the posted code was written by you.
Regards
John
