Introduction to Environment Variables

19/03/2018 by

Environment variables are used to communicate between different t programs or with a PC using CANlib. Figure 1 shows three scripts that are currently running on a Kvaser device. When Script 1 sets an environment variable, the new value will be available for reading in the other scripts, as well as from a PC using CANlib. In addition to this, a script may also declare a hook that is run whenever a specific environment variable value is set.
