Hello All

Sorry for all the mess my previous email caused...I am reposting it here in Human Readable format :-)

>Yes, the question is on where the ports physically are. Thanks for the link...I thought that there were more pins on these two sockets on >the top of the waysmall...So these are the serial ports in those mini sockets right? This brings us to another question  :-) , Where are the >GPIO ports accessed in the waysmall?

(if your question was "where":)
About 15 free GPIOs are accessible on the back of the waysmall-board.We drilled a hole into the waysmall-case.)

OK, spotted the difference...So the slot on the side of the waysmall, is for an MMC?

>Thanks very much, i am allready taking a look at these libs</P>=0D

Is there a relatively accurate method of timing my current code (i mean an application i am considering bringing to the waysmall) in my development machine and then see if the processing power of the Waysmall is enough? (I mean a method to convert the perfomance benchmark of the current developing machine in waysmalls processing power)
I understand that the easiest thing to do, would be to find a slower machine and try it there, but believe it or not this is not an option for the time. 

For example, if i obtain a profile of the processing core (The part of the application that does all the intensive math) on the current machine that runs at 3GHz what do you think would be a realistic factor to multiply by to convert the profile so as it had been obtained from a run on waysmall? (I hope this makes sense somehow  :-)  )

Note that for the time all the processing is done on "double"s which i believe would produce "slow code" for the waysmall...I could convert it to Fixed Point but why bother if it is not necessary?

All the best.
