KL82Z - PORTD interrupt in PEX

nickbedbury — Tue, 16 Apr 2019 17:58:17 GMT

I am trying to figure out where to enable the PORTD interrupt via Processor Expert. I inherited a project (originating from the SDK demos) where only PORTA and PORTC are enabled currently.

As shown in the attached screenshots, everywhere I've located so far has the option disabled and it cannot be modified.

Surely PORTD can be utilized for interrupts on the KL82Z? Is this a bug with the "Kinetis SDK 1.3.0 Standalone for KL82Z" package possibly?

Hi Nick

KL82 supports interrupt and DMA requests on all of its 5 ports.

Mark

Hi Nick Bedbury,

Please select generate code for PORTD IRQ handler first.
Then you can see the PORTD Interrupt enabled.

Best Regards,

Robin

Thanks Robin. I think there was some glitch in the Linux KDS IDE. I re-opened the project in the IDE in Windows and was able to select "Generate Code" under the Events tab like you showed. In Linux, this was also a read-only setting.
