PingMonitor with wiringpi (new drivers)
Forums:
Hi,
has anyone rewritten the PingMonitor-Script (https://www.piborg.org/pingmonitor) to work with wiringpi ?
Thanks in advance!

ok, I've tried it myself and this is what I could come up with. It's working for me, when wiringpi2 is installed:

Cool :)
Glad to see you managed to modify the script so it runs again.
Thanks for sharing :)
