3rd Party Lua Control Drivers

Cognio lets you control and integrate third-party devices using drivers written in Lua. A driver runs on the Cognio device and can open network connections, send and receive messages, react to control changes, and drive controls in your design.

The Lua API is extended with a set of libraries specific to Cognio. Use these to read and write controls, talk to the device, open sockets, run timers, and work with JSON.
