Thanks for your interest in the Intel® Edison Platform.
I was thinking how you could display all the GPIO configuration before using the echo command to change them, and you could create a script that query all the GPIO configurations, for example:
- Create the script
- Make your script
echo <description> cat /sys/class/gpio cat /sys/class/gpio/gpio<pin#>/direction cat /sys/kernel/debug/gpio_debug/gpio<pin#>/current_pinmux …
- Set up permission on a Script
chmod u+x script.sh
This might give you an idea to create the script and customize it to meet your needs.
Hope this information helps, also, if you have any other question, don’t hesitate to contact us back.
Have a nice day!
