Spin Semiconductor

Hi,
I've created a basic tremolo algorithm but want to be able to alter the sine wave shape. This would be much easier on a general purpose processor, but how can this be accomplished with the FV-1?
Thanks.

Where can I find Application Note AN-0001 and any other app notes?

Thanks again. Finding a book that is neither too basic nor too far over your head is a personal thing indeed.

Thanks for the help. I don't have a scope, so it may be time to invest in one. Apparently another part of my algorithm is suspect. I appreciate the help on constants also. So if I understand this correctly, the following is true when loading the ACC with constants: $7FFFFF = .999... $100000 = smalle...

To help the new guy on his journey, do ya'll have any recommedations for books on DSP? I have programming experience and understand the concepts of how chorus, delay, reverb, etc. work, but how these effects are created with a multiply-accumulate instruction is a mystery. Thanks.

I new at this, so please excuse my basic question. I want to toggle a variable between two states. The following code doesn't seem to work. What gives?

clr
or 1
wrax toggle, 0 ; toggle = 1
.
.
.
ldax toggle ; flip toggle
xor 1
wrax toggle, 0
