How is it going with testing of last PCB version for 55nm Avalon?
Is anybody have assembled K16 Gen.2 version?

DHL called me like 2 hours ago, that the PCBs are in the country. Now the package has to go through the customs, so I'm expecting them delivered at the beginning of the next week.

 Grin That's great.


BTY, Can I ask something about klondike firmware?

In klondike.h, at define section. there is an constant "21.33uS" in the comment.

It is 0.00002133 sec.

what means that?

Where 0.00002133 is come from?

I would say it's based on a PIC freq. (48MHz) and some prescaler value, so basically something like 1/(48x106/some value). And it would be the time it takes the Timer0 in the PIC to do one click.
