How to use the niosii interrupt service program

please tell a little bit more,

what version of quartus, nios, hardware are you using

can you start the proram in debugger ?

can you set a breakpoint in the interrupt ?

does it enter the interrupt routine ?

static void handle_button_press(alt_u8 type, FILE *lcd)

{

/* Button press actions while counting. */

if (type == &#39;c&#39;) // <-- set breakpoint here
