Oscat Basic

An Oscat basic library for RuSTy

A modified version of the Oscat Library that could be compiled using RuSTy.

In its current status, not every feature of the library compiles.

Build Oscat

StandardFunctions are needed to compile Oscat.
To avoid compile errors, stubs.st includes stubs for functions that are not part of StandardFunctions.

To build Oscat, plc.json can be used as the build description.

NOTE: Paths need to be adjusted in plc.json
for more info see RuSTy build with build configuration
