i ve an Router from Buffalo WHR-HP-G300N.
I need an free GPIO (output) to drive an input for an external board with microcontroller.
My problem is i found no unused gpio (pin from the ic).
How can i find an free gpio?
There are two ics from Atheros:
AR7240-AH1A and the AR9283-AL1A
I search for the datasheet, but i found no datasheet for both ics.
Thx a lot for your help!
