Sorry, I move to a new place and for a couple of days I didn't have
Internet.

Yes and not, as I didn't have internet to upload the asm to my repo I send
a asm with macros and a little try to instruction schedule. I need to debug
it.

Well, this is something interesting. I think that this apply specially for
the first half of the summer, because the project begining was specially
hard due I didn't have a lot of the needed knowledge, at this point maybe a
task check list would be fine with deadlines. Now I have deeper knowledge
than before but I feel that I spend to much time to get it. Any way as I
said before this was a good sperience because I have gained experience in a
bigger project than my university assignments.

Thank you I will move to it after I debug the asm code.
