Question: resolution 12/12 bit with AOUT_LC

[Janis1279]

I am building Midibox FM.

I have question about a AOUT_LC module.

AOUT_LC with 3*74HC595 chips on pcboard will be possible 12/12 bit resolution DAC's.

Will that configuration really workable 4*AOUT_LC with MBFM? Is it not so slow?

Sorry my question! I am not any expierence with DAC's.

Thanks!

Hi Janis,

No, this configuration isn't supported by the AOUT_LC driver.

Will that configuration really workable 4*AOUT_LC with MBFM? Is it not so slow?

Yes, it will be slower. There is a higher danger for MIDI IN buffer overruns.

The best solution to get 8x12 bit is the usage of a AOUT_NG module, since it doesn't require to update all channels if only the value of a single channel has changed. This improves the performance significantly.
