[sdiy] AVR/ARDUINO psuedo random noise?

[dan snazelle]

I am looking for advice or example code on how one might use the Arduino/AVR32 as really long shift register for digital noise.? 

i would think it could be done, using one input for clock and another input for data and using software XORS?

it seems like this would be one REALLY great use for a micro would be creating interesting shift registers.


anyway, thanks for any links or help
