plz help me
thank you Mr.Erik Malund I tried in your way and it work's.but i have a question. When the line
bdata unsigned char ON_REG;
is wrote in the define.h file it not working can you explain me why it happens the file define.h is included properly. itworking nice for the other code
"... in the define.h file it not working"
In what way, exactly, is it "not working"?!
How do you expect anybody to help to fix your problem if you don't actually say what the problem is?!
If you phoned a mechanic, and just told him that your car was "not working", do you think he would be able to do anything based on that??
Anyhow, as we're talking header files, what normally happens if you put a variable definition in a header file and then include that in multiple places...?
thankking you for the advice form this post i will take care of all these thingputting a variable definition in a header file and then include that in multiple places...? but this file is only included in this project only so what is the problem.
"but this file is only included in this project only"
How many source files in the Project?
"so what is the problem."
I have no idea - you need to clearly describe what problem you are seeing!
