Will there ever be a Tiva with I2S?

I've seen the app note for using dual SPI to emulate, but it's for the 1230 not the 1290, so it's taken some work to get it going on the 1290. I'm not too fond of taking up two SPIs for this, especially since it's a peripheral that used to exist natively in the old Stellaris series. Seems like kind of a hackjob to have to use two ports to do the same thing that one peripheral used to do. Will TI be making a Tiva with native I2S?

    Hello DWF,

    I would need to check with Mktg on any plans for a native I2S for TIVA. Will keep you posted on the same.

    Regards

    Kind of you to state, "kind of a hackjob!" (repetition by design)  Seems to fully meet "x-job" definition - to this reporter.

    Pity that baby (neat I2S feature) got tossed - along w/bath water - in the seamless (yet not quite stellar) transition...  Feel your pain, buddy... Many different sails/sterns afloat this ARM harbor - some need not await, Mktng...

    Well, in many years as a software guy, I've been known to have to throw together a hackjob or two, myself, in the face of otherwise insurmountable roadblocks. I wouldn't have the slightest clue what kinds of things get in your way when making an MCU. Figured I'd ask, on the off chance it was either an oversight, or an upcoming feature, rather than some kind of emergency forcing them to forego it. I can imagine some overworked engineer losing sleep and/or hair over an impending doom along the lines of "if we ship an I2S in this product at this time, some quantum computer at the warp drive research center will accidentally divide by 0 and turn the earth into a black hole". Hopefully it's nothing that severe, of course. :)
