Why not to use one of the PWM outputs?

It all depends on the interface you have for your DAC chip. Either one could
work.

Hi
I am using the TI DSP eZdspf2812 DSP as a waveform generator. It is
interfaced with a microcontroller. Basically the DSP acts as an encoder,
ie it accepts a finite number of bits (1s & 0s) from the microcontroller
and generates a waveform corresponding to the bits. Is the GPIO good for
this interface between the DSP & microcontroller?
Also the waveform goes to a D/A converter. Is it better to use the McBSP
or the SPI for outputting the waveform?
Thanks.
