Hi all,
I'm using a simple circuit to read led pulses from my electricity meter
and am now using simple C code to poll the parallel port to detect a
high/low change on pin 12. (see http://offog.org/code/electricity.html)
My new server probably won't have a parallel port anymore. So the question
is: is there a simple manner to read 1-pin high/low from USB under FBSD?
Any examples anywhere?
Thanks!
Sven
