Trouble with interrupts

Hi Leela,

Thanks for your post.

Please keep breakpoint on the interrupt and check whether the control goes there and comes out of the sane.

If the code breaks & comes out, it means the interrupt is activated.

Also, try to check the interrupt control registers of dsk6713 using datasheet specifications and please read the register values, there by we shall ensure the particular interrupt got activated or not.

hi,

i kept a break-point on the interrupt too but still the yellow marker is at 'while(1);' statement itself

Hi Leela,

Thanks for your post.

Please make sure, your interrupt control register are set properly in the code with the help of datasheet specifications.

We shall control interrups using its control & status registers.

Hi,

There are include provided along with the software.

In that there is a function 'comm_intr()' which activates the board along with enabling global interrupts and activating 'INT_11'. Hence i guess they are activated properly. Its also explained in the book of 'rulph chassaing', which is a suggested book by your website, that the code would work.

Whats the issue here then?

Thank you,

Hi Leela,

Thanks for your post.

If your interrupt is properly activated, as per routine mentioned in the above code, the LED is supposed to turn OFF.

But in your case, the LED is ON and this shows, the interrupt is not activated,  I guess.

Please make sure your interrupt is activated.

Thanks & regards,

Hi Leela,

Thanks for your post.

Inorder to check whether the interrupt is activated or not shall be done only by accessing Interrrupt control and status registers and check the status on the same.
