I read that someone had used a 8 pin PIC to generate White Noise (similar to the discontinued National MM5437 or AMS S2688 chips. I know I can do it with a Zener diode or a 3-4 chip shift register circuit (which is how I am doing it now.) Can anyone help me with this? If I could do it in the PIC, I have some other things I would like to use the PIC for as well. tks Mike Mike Montaigne Neutron Program for Materials Research Steacie Institute for Molecular Sciences National Research Council c/o Atomic Energy of Canada Ltd.
