on BeagleBone Black, which isn't running any Slackware yet (at least here on my place) there is a fanciful eye caching feature present:
The hear-beat like pulse on a led.
it is most useful for an headless computer to quickly (at a single glance) discern it's load and simple works or is locked state.
Any more than that would need an monitor or a proper "
blinkenlichten" panel.
So i figured, why not have it working in Slackware too?
To my surprise i found none "easy way" writeup, so i figured i make one here?
Okay here goes (ready to paste in rc.local):
Code:
# hearbeat madule load for green led:
modprobe -av ledtrig-heartbeat
echo "heartbeat" > /sys/class/leds/orangepi\:green\:pwr/trigger
for my orange PI PC
or
Code:
# hearbeat madule load for green led:
modprobe -av ledtrig-heartbeat
echo "heartbeat" > /sys/class/leds/bananapi\:green\:usr/trigger
on my banana Pi M1
ammounting to:
Code:
# hearbeat madule load for green led:
modprobe -av ledtrig-heartbeat
echo "heartbeat" > /sys/class/leds/*\:green\:*/trigger
for any green LED to be triggered as heartbeat indicator.
I post this in hope someone finds this useful.
