Even if you solve this problem today, you will have to re-solve it
again and again over the life of the project. Better to re-code it
in C. In the past one could get better performance with hand written
assembly but today the uP chip has 100X more space than needed.
In fact I, and I think most others have moved on to using small uP
development boards rather then bare uP chips because the little boards
come with USB programmers, chock crystals and everything you need and
might cost something under $5. They are dramatically easier to use
as most have a row of 0.1" headers so you can connect your custom
electronics. This is not the way to go if you want to build 1,000
units but for a few tens of units it saves quite a to of work.
Especially if a software update has to be done after shipping. The
board's USB connection saves end users much hassle.
