Yes! That was the thread! I've read so much stuff I forget where I see certain things. The explanation of the state machine was very easy to understand and it made perfect sense to me. Now I may not be able to write code for one just yet but I think the concept you provided in the manner you did takes the mystery and mainly fear out of working with these wonderful little devices. Like I said, it sounded very interesting and may have a place in what I'm trying to do but I need to work on easier stuff first.If it was this thread: ....

This also sounds useful. I'll file it away and take a look at it when the time comes. I think I have more than enough on my plate now to keep me busy for a little while. You've given me some things to seek out and gain more knowledge on and I'll do just that. Right now my modified "Blinky" code code contains about 15 lines of DELAY using 1 microsecond each. I know that is not much but as you said, the machine is not doing anything else during that time. That may hurt me farther down the line as the code gets more complex.We have people here in the Forum who know all about timers and interrupts if/when you want to learn them.
Too funny! Almost like.... here, hold my beer and watch this! (not that I know anything about that)...OBTW, where's the fire extinguisher?
