- Hi Mary,
Be sure you are linking to the rt library which implements that call (as well as including the time.h header). Use -lrt as a linker argument to do this. - MW 12:34 PM Software Development: RE: How to get system time?
- Did you include <time.h> in your code?

Tried clock_gettime() but got a linker error: "undefined reference to `clock_gettime' "
There was also no reference for CLOCK_REALTIME, or CLOCK_MONOTONIC.

The RS485 board has an enable that must be managed. I believe you need a newer version of the driver to control it.
Support for the RS-485 board was added in commit 3e1a3878bbe545b7d4a2ab65023a9938b0d5984e
