[arm-allstar] How to use Raspberry Pi GPIO pins to connect and disconnect a node

[Steve Sedgwick]

Hi,

Has anyone created a way to use two GPIO pins on a Raspberry pi node to 
connect and disconnect that node to another node or hub? What I want to 
be able to do is on my node I want to be able to press a pushbutton that 
is connected to a GPIO pin on my node and that press causes my node to 
connect to a predetermined node, for example connecting node 12345 to 
node 54321.  I would also like to be able to press a second pushbutton 
and disconnect my node from a predetermined node, for example disconnect 
node 54321 from node 12345.  I want this for my mobile node so I don't 
have to dial the normal node connection/disconnection sequences.  It's a 
lot easier for me to press one button on my node than it is to press 7 
or eight touch tone keys on a microphone or HT while drive down the road 
a 70 mph.

Thanks, 73
