Hi Guys,

I am afraids these postings get too long for me te keep up :(

Please consider:

- Determine the quality of a pseudo random sequence is mathematics.
I've choosen a pretty good algorithm (according to the info I found on
the net) and would suggest to use it or switch to a weaker on if you
need to save time or flash space. Or of course a better algorithm, but
i've not seen any valid arguments for this.
- It would be good to have - in addition to the algorithm at hand - a
way to generate a seed that is non-deterministic, even when this is
low-quality like using unconnected adc registers or memory value. This
generator should works on any pic (or at least most pics) and is
independent of external components.
- The suggested methodes could give such a seed, but will provide much
less quality (pseudo) random than the algorithm at hand. So please
don't consider it a replacement.
- Real random (opposed to pseudo random) requires some external source
like atmospheric noise (see http://www.random.org/). The avalanche
effect of a semiconductur might be a local alternative
