CCS/TM4C1294NCPDT: Creating individual ISRs on GPIO Port P and/or Q?

Part Number: TM4C1294NCPDT
Other Parts Discussed in Thread: EK-TM4C1294XL

Tool/software: Code Composer Studio

Hi

I am still a bit new around this, but...

I want to use an EK-TM4C1294XL to, among other things, control two parallel data streams with individual handshakes. (HP-1000 like, Jurassic era, I know)

In the processor manual, I can see, that for ports P and Q each pin should have individual interrupt vectors, which is exactly what I an aiming at.

But is it as simple as that? Simply write two ISRs and connect them to two of those pins?

I have not yet found any example code digging into that little individual vector feature. Maybe because it actually IS easy?

    Yes it is! :)

    Have a look at our 'interrupts' example for the EK-TM4C1294XL LaunchPad in TivaWare found at:
