Thread: Dropping from a ucCount to a while loop

In embedded programming it is very common to have an endless loop most often in the main function.

Likely your program is ending because I see nothing the stops it from ending.

Edit: In your code, I would try adding an endless loop after the line below.

Code:

bSecondTest = TRUE;

Edit2: Please try to use spaces instead of tabs in your code; mixing both of them makes your code look bad.

I'm guessing the OP is programming a "free standing" environment, in which case any so long as main (or whatever the documented entry point) is defined correctly for that environment, it's all good.

@OP

Code:

void interrupt high_priority High_isr(void)
{
     while(bSecondTest == TRUE)

This is flat out wrong.
An ISR needs to execute as little code as possible, then "get the hell out of Dodge(tm)".
A while loop that loops forever will prevent your mainline code from ever running again.

What happens if you fall off the end of main()?

That seems about right.
> while(TRUE) //Loop once
Erm, no, that's loop forever.
Which in the absence of any break statements inside the loop, it really means forever.

Most of the comments don't really agree with what the code is doing.
It's hard to figure out your real intent.
