pigpio?

[knute]

Is it possible to run two programs using the pigpio libraries at the same time? I'm getting an error that leads me to think that isn't possible.

Thanks!

Only one version of the library can be running at a time.

If you create a C program and link with -lpigpio that program will become the pigpio daemon when run. Other programs will have to talk via the daemon interface.

For Python that is handled by importing the pigpio module. A C program needs to use the pigpiod_if2 interface.
