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. Vikram
