20*log(a/b) caculation
I have a application of calulating LOG function, I know PAK-2 math co-processor
can do this, How
do I connect this PAK 2 with BS2 ? After calulation I need send out to 16*1 LCD
. Is there anyone
help me out ? I have some experience of BS2, but how the BS2 know floating
point math when I
connect PAK2 ?
Sorry ! I have no idea of PAK2 .
TIA
Baker

how to interface to a stamp or pic, both look very easy and straight
forward.

page that shows some ways to do logs within the restraints of the stamp's
integer math:

Best, Duncan
provide a small library that allows you make calls like:
gosub floadx
gosub flog
To do the work. Sending the data out to the LCD could be done using the
fdump command (changing debug to serout -- assuming a serial LCD) or you
could convert it to an integer (FInt).
You can find the manual and many examples in the document library at
http://www.al-williams.com/awce/doclib.htm
