Generating various waveforms with resistive DAC, how to alter pitch?

[schu4647]

I have one of these. If you are interested I can program it with your wav files and it will be ready to go. Go to my site and buy 3 of my diaper checks and send me a note that you want the ISD3800 board instead. www.thediapercheck.com. I am really just giving you the board for what it cost me. It can be difficult to program.

A manual delay should be as fast as asm if you have
defined no clear watchdogs to be inserted in code,
and configure the chip with watchdog off.

delay = 20

...

for count = 0 to delay
next count

For something quicker you could set up a number of delays
