Bidirectional IO #21

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Seems that BCM2835 does not support open-drain IO, but could it be possible to 
make sw emulation for it?

setup to opendrain

when output set to 1, configure as input and enable pullup (or allow pull-up 
configuration).
when output set to 0, configure as output and drive low.

Allow reading input state, when output set to 0, return 0, when set to 1 return 
true input value.
