Hi,

Check that you have " int main(void) " in your program!

Dave.

Thanks, it is alright now :D

The reason that I am referring this lib is because I am trying to write a sample lib which inherits the Serial Class from mbed.h, I could manage to compile the code but there is no output at all when I run it.

I am thinking it might be a inheritance problem for OOP. I have no idea what's wrong and stuck by that now ...

Could anyone take a look of my sample class which is the only repository under my profile.

Thanks a lot !!

Terry
