Documentation

Examples

Library contains several examples of usage but please note, that this code is just for educational purpose and not production ready. Examples are from several contributors and they are not tested and it is also not known, if they really work or can compile at all.

The core library itself is well tested and has more then 93% of the code covered by unit tests and integration tests and tries to be SCPI-99 compliant as much as possible.
