Thread: Fire IRQ, triggered from Source Code...

  1. #11

    Thanks for Support, but I have no SKit2Go here...

    BUT, In the meantime, I find out, that my DAVE-APP solution is working...


    I define in "Manual Ressource Assignment / INTERRUPT / NVIC-Node: XXX"

    Otherwise I get a Hard-Fault.

    I can define the node numbers betwwen 2 and 31...
    Some are working, some results in Hard-Fault...
    e.g. Number 10 is working, I am using that now...

    Please, May somebody can give me more backround Information, why and which Node-Numbers I can use, or use for best case ???

    Best Thanks.

    So the previous problem is due to unassigned NVIC node?

    In the XMC1100, most of the NVIC nodes are assigned to specific service request lines of the peripherals:

    The interrupt handler is not implemented in DAVE for the NC (not connected) lines, though an exception is IRQ2.
    These are the ones causing the default handler (from startup file) to be entered.

    For your purpose, I would suggest to use IRQ2 or whichever nodes (IRQ10 is USIC0.SR1) that are not used in your application, for the SW interrupt.

    Hope this helps.

    By the way, the code that I provided can also be used for XMC1100 boot kit but probably you don't need it anymore.

    OK, I understood.

    2 is already used...
    So I am using 6, and it's working fine.

    Best Thanks for help!
