You're a trooper. Thanks for letting me know. I think I will get some boards
and sleep better at night knowing they have a better chance of working.
After that, I'm hitting the code.
FYI, I have access to a Pro XC-8 compiler; if you need me to compile anything
let me know.
What are your plans on sharing the source development? If you plan to keep it internal,
that is fine. Would just like to know to avoid reinventing the wheel.
I just tried with 4x work queue, pre_calc 6 words, 8 nonce range words and 2x result queue in RAM (plus other core stuff like USB buffers, and status and cfg registers). I have more code to do but I think this is all the main data chunks required other than the odd temporary byte here or there. RAM usage is currently 805 bytes. I'm fairly comfortable that we're good for RAM.
I may take you up on that XC-8 Pro offer later. It may well be crucial to fitting the code in 8K. I can enable the trial 60 days but then why do that until absolutely required (or I'm curious if you can do that in a VM and then wipe it after expired?).
I'm going to release the firmware and driver code once it's working. I was thinking of all that stuff to protect it but to be honest that's just is a hassle. I'm going to just trust that people will choose to support the vendors that kick back a small fee. Or even better maybe they'll mine a few hours for me by their own choice. I'll put the mine-to address out there when it's time. I'm getting a lot of help/support from forum members here and I think it's better to respect that by not having locked code at all.
