Interrupts with KDS

JohnMusselman — Tue, 16 Dec 2014 20:23:00 GMT

HI,

I am moving some code from an MK20 part (written with Code Warrior 10.6) to the MK22FN512 and using KDS. Apparently KDS handles interrupts differently than CW and I am having trouble. KDS does not give me access to the NVICICPR and NVICISER registers. I need to know how to 1) enable an interrupt in the NVIC and 2) to point the interrupt vector to my interrupt routine.

Can anyone help? Sorry for such a simple question, but I'd rather just translate these two tiny bits of code and be on my way rather than spend a week figuring out processor expert or digging through the overwhelming documentation.

Thanks in advance!

John

Jorge,

Thanks. Yes, with KDS the definition of the NVIC registers has changed. NVICISER1 is now NVIC-->ISER[1], for example. The proper files are already included in the project. I'm still trying to get the board to work so can't verify that this and the interrupt vector actually work, but it does build now.
