Hi Vince
Thanks for the suggestion. Issue was solved long ago but I didn't update the
post. But you are right with the use of inductors and you also need to change
the mode selection to out the port into host mode.
Kind Regards

Hi Brandon
Thanks for the reply.
I will summarize here what i found about controlling a GPIO and about using
interrupts.
1. Using sysfs one can easily control the gpio and using threading can
re-create pseudo-interrupt from user space. Found a useful project called

Everything else.
Technically, as what is in the reference material, the rPI is supposed to
use less power too. However, according to the documents I've read, this
does not include the power used by the graphics. Which can be quite
substantial.
I should mention that the rPI's graphics are nearly or exactly impossible
to disable the graphics chip. SO that additional power that is not counted
in the power usage benchmarks will always be used.
