Cli() & delayMicroseconds() & nop()

What a weird topic name isn’t it ::slight_smile:

I’m trying to do a quick and dirty port of a timing critical code (guess from which platform ;))

  1. I have critical section I would like to protect from interrupts, any interrupts, any disturbance.
    While the code has a single thread, there is still timer and serial interrupt that could break my code flow.
    So I am looking for an equivalent of cli()

  2. I also need to do fine tuning delays in the microsecond domain (from 10 to 1000), so Thread.Sleep() is not an option.
    If there is no existing function, can I use a timer ?
    Reading timer counter until it reaches a value would work.
    How ?

If you are about to say RLP, cross the street to the other side.
I said quick_and_dirty ;D

Thanks

I would tell you the solution, but you would not be able to hear me from the other side of the street.

It’s nice over here on this side of the street, isn’t it, Mike?

Quick = writing native code in notepad
Dirty = doing so while drinking a martini

How is that not RLP? :wink:

Sometimes in correct answer is not the one you want to hear.
