gpio expanders ? We're having some issues here where toggling the last
gpio pin (gpio 15) on a PCF8575 device causes platform to hang and I
can't come up with any explanation of why would it hang...
I know.
I can try toggling I/O 15, but that will need to wait until next week as I'm
currently travelling without access to the hardware.
a board issue, or PCF8575 is a bit screwy ;-)
Thanks
