Applications for direct DAC mode
Posted: Sun 2017-07-02 9:05
What are some applications for the direct DAC mode of the VS23? Some that I can think of are:
- Using the DAC by itself. Set the clock divider to its lowest value and the buffer length to 1; write to the start pointer position
- Arbitrary waveform generation. At lower divider rates, the 10 vclk gap at the end of a "line" shouldn't be significant
- Audio playback. Instead of looping a single wave, set the start pointer to successive segments of a longer waveform. There doesn't seem to be a way to determine the position within the buffer so knowing when to move the start pointer again requires keeping track of time another way.
