coldfire: why can't I use the sleep function?

Ivychacha — Thu, 12 Oct 2006 17:29:12 GMT

Hi all,

I'd like to use the sleep function in my code and I've found the definition of this function in the CW help:

#include
unsigned int sleep(unsigned int sleep);

But when I tried to use this function in my code i can't compile it, getting link error "undefine funtion: sleep".

Am I doing something wrong? why can't I use this function?

Any ideas? I'm confused :/

Hello

Which CPU are you targeting (HC08, HC12, Coldfire, ...)?

Are you using an OS on your target?

Hi crasycat,

sorry I forgot that information

I'm using the ColdWarrior 5.7 on a MCF5235BCC EVB.

Hello

In our embedded products, we usually do not provide source code for time management functions as

these functions are board and OS specific.

This leaves customer the choice of implementing their own time management functions.

If you are using an embedded OS, you may want to remap the sleep function to some OS

related function.
