i have multiple projects going on
one idea is to really use it for audio
and the other is similar to what has asked.. (found it just a minute ago
)
i think that bit banging is to slow to get really nice smooth fades... (and that is the key requirement)
so that was the source for the idea to use the i2s lines...
i will read some more about this hole thing.. but i have the feeling it will get complicated..
