Hi

I am using the TI DSP eZdspf2812 DSP as a waveform generator. It i
interfaced with a microcontroller. Basically the DSP acts as an encoder
ie it accepts a finite number of bits (1s & 0s) from the microcontrolle
and generates a waveform corresponding to the bits. Is the GPIO good fo
this interface between the DSP & microcontroller?

Also the waveform goes to a D/A converter. Is it better to use the McBS
or the SPI for outputting the waveform?

Thanks.

Vikram

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.
