[arm-allstar] Radioless Node - push button switch to run connect to hub/node script

[larry]

Rob,

Did you get this all working?

To me it would not be much different than the Shutdown function example 
as pointed out by others.

The main difference is to create different macros for each function and 
instead of running the shutdown function point it to a script that runs 
the proper macro for the function you want it to perform, The push and 
hold time can be lowered to your preference

Referring to 
<https://www.crompton.com/hamradio/hamvoip-howto/GPIO_how-to.pdf>

Example Script to read a bit
Another very useful 'gpio' command is 'wfi'This command waits for an 
interrupt based on a rising or falling
level at a pin. It takes no processor time unlike polling. The command 
syntax is:
gpio wfi 1 falling|rising
This example is from the shutdown monitor code I written for the RPi2
#!/bin/bash
# Required button hold down seconds
HOLDTIME=6
# set mode to in and pullup pin 0 (Physical pin 11, GPIO17)
gpio mode 0 in
gpio mode 0 up
TIME1=1
while [ 1=1 ]
# wait in interrupt for pin to go low
gpio wfi $PIN falling
do
# Got the low now poll to see if it stays low for holdtime
while [ `gpio read $PIN` -eq "0" ];
do
sleep 1
let TIME1+=1
if [ $TIME1 -gt $HOLDTIME ]; then
# if greater than holdtime then exit past done
break 3;
fi
done
TIME1=1
continue
done
# code to execute when holdtime is exceeded goes here
