Timer Interrupts on Due

ivanseidel:
Hi,
Apparently you have only included the header file... no implementation is made to the class DueTimer.
Why did you added the header to the code, instead of including the library? Did it compiled? Did you installed the library correcly, and examples are on the examples menu of arduino IDE?

Dear Ivan,

Let me explain you what exactly I do. I go to the Simple Timer and copy and paste it in a new Arduino page and save on my desktop. (It has the header #include <DueTimer.h>)

Thereafter, I go to the header file and save it on the desktop as well beside the Simple Timer.

But when I run it has the following error:

fatal error: DueTimer.h: No such file or directory compilation terminated.

Can you please kindly advise me about this?

Thanks.
