I'm looking for some help with two simple 56k dsp programming tasks:
1. sit in a loop til an external voltage level goes high
2. delay a host-specified number of milliseconds, and then
produce a short tone.
For the first task, I imagine that I should use one of the SCI pins.
Since I'm doing this on a NeXT, the second task should probably
play the short tone to the NeXT sound hardware.
I've pored over the sample programs NeXT provides, but either they
don't do what I need, or I missed it. I think that I *do* understand
how to use the SND functions to load and run a program on the dsp.
I've made some progress from reading the DSP User's Manual, but I've
only moved from a state of total blindness to one of partial vision
in one eye on a moonless night...
I'll be grateful for any help, especially short dsp programs. Thanks.
