ALDL stream recycle time

[Dave Zug]

You mean that the stream is not simply 'completely' populated and THEN spat
out, that it reads each location just before spitting it?

I see. so theres hope. all that other stuff the 730 spits out decreases the
number of samples per second compared to the good ol '165.

Putting the good stuff in the first 10 bytes and shortening the quantity
transmitted to 10 would do it if I could have my way.. but the 63 thing
works if like you say it changes a few times during the 63 byte transmission
time.

Thanks John!  Food for thought.
