Re: TI-H: IR detecter
Definitely. Either an 82 or 92. I will soon know 82asm so this would be
the best. I am planning on using it with a slotcar track for test times.
Will it work in a lit room, over a distance of about 5"? What parts do
I need? Are the scematics posted somewhere?
Once I study asm this next week, it should be easy to write a program
that gives me an interval for how much "time" it took to do a lap. (Time
is not real time, but merely a relative number from a loop, so time is
more like "Cycle", but the lap loop numbers would still all corespond
relative to each other, which is all that time would be used for anyway.)
