Hi,

I've implemented a Perl script using this page as a template: http://playground.arduino.cc/interfacing/PERL

The while(1) loop uses 100% of the CPU power available. Is there a way to do this without using so much processor load? In my case the Arduino spits out a line of telemetry once per second. The perl script reads this and inserts it into a db. Any suggestions about better ways to do this? Thanks,

David

put in a sleep of a few (10) milliseconds as the hardware will buffer several characters anyway ?

#include "all disclaimers"

Code:

#include "all disclaimers"

What operating system allows spaces in file names?

Windows seems to.

Try using "select" to wait for data with a timeout.  I think it's in IO::select.pm or something like that.

Thanks, sleeping fixed it up. Seemed silly that such simple code would chew so much. Thanks,

almost all?
and yes spaces are mainly for us mere mortals to help our associative brain
and yes they cause a lot of trouble (almost daily! )
