GPIO Toggle Script for JS8Call

ptt.sh

#!/bin/bash

STATE=$1
PIN=12
if [  $# -le 0 ]; then 
    echo -e "\nUsage:\n$0 state \n" 
    exit 1
fi 

if [ "$STATE" = "on" ]; then
    echo "toggling gpio $PIN on";
    gpio write $PIN 1
else
    echo "toggling gpio $PIN off";
    gpio write $PIN 0
fi

How to use:

1. Copy this script to a location on your machine
2. Edit the PIN variable if you need it to be a different GPIO pin than number 12
3. Make the script executable: chmod +x /path/to/ptt.sh
4. Test that it works: /path/to/ptt.sh on and /path/to/ptt.sh off
5. Configure JS8Call to use it as a PTT Command: /path/to/ptt.sh %1
