Running Once?

Where can I put my code so that it will execute itself completely only one time. So, if I turn the bot off and on, it will run again. There was a section in the UserRoutines.c FUNCTION NAME: User_Initialization that says it only runs once, but this doesn't seem like the right place for my code.

Re: Running Once?

Make a function somewhere in user_routines.c, put your code in there, and call that function from User_Initialization.

At least if you are trying what I think you are trying to do.

Re: Running Once?

What is stopping the program from going down the program and calling it, then it hits it again later and runs it? Is this programming language run-by-call-only and not run down the program. Right now I went into the users initialization and just pasted in my code snipet after where it says */Add you own...*/. Looks kind of messy, but only the robot will know :).

At least it's supposed to... ;)

Re: Running Once?

Once I call my function, does the function need to link back to the user initialization part just before it left off. I am assuming that it will automatically go back to right after where it was called upon completetion.

(If you didn't put in a return than the compiler will insert one for you at the end of the functions definition)

Re: Running Once?

There is a simpler way of having something only run once...

Code:

int counter = 0;

if (counter == 0)

{

do whatever you want once;

counter++;

}

It will never be executed again unless you set counter = to 0... you can change the variable name too and name it whatever the function is supposed to do such as camera_settings, etc...

That will be called every time unless counter is declared as a static int
