Using "consumer" to describe the current state of the line

[o-alquimista]

Is it ok to use "--consumer" to hold variable information on the current state of the line? e.g. --consumer="my-script-current-power-50%"

# gpioinfo -c gpiochip0 GPIO18      # my script would parse this
gpiochip0 18	"GPIO18"        	output consumer="my-script-current-power-50%"

This is assuming the line can have more than two states, so you cannot rely on the active/inactive description. In my case, I'm doing software-timed PWM.

I believe it should be ok to do that — it's just a string after all — but who knows, there could be a better way. My alternative would be managing a text file in /var/run/.

You can put whatever you want into the consumer string. How are you managing PWM with libgpiod is a mistery to me though. :)

I'm using something like --toggle 50ms,10ms to get a slower fan speed.

just a reminder that GPIO_MAX_NAME_SIZE=32
