Problem with integrating Qsys system in Quartus with created Qsys PWM module

Thanks for your feedback, I think I'm starting to understand it now, I'll try this tomorrow when I have the DE2-115 board available.

I'm wondering how I can make use of the header (.h) and source file of altera_avalon_pwm_routines to use the following functions for a cleaner code:

altera_avalon_pwm_init();

altera_avalon_pwm_enable();

altera_avalon_pwm_disable();

altera_avalon_pwm_change_duty_cycle();

I now have placed the header file under HAL/inc and the c file under HAL/src, in the main I included the header file:

# include "altera_avalon_pwm_routines.h"

But the header files includes "altera_avalon_pwm_regs.h" so I place it at the same place?
