Neuron® C Developer Center

Develop more productively and reduce your time-to-market with the Neuron C programming language!

Neuron® C lets you create LonWorks® applications for Neuron processors and smart transceivers. Its extensions for network communication, hardware I/O, and event-handling, and its familiar ANSI C-based programming environment, offer power and ease.

Features

Based on ANSI C for a familiar programming environment
Provides a network communication model based on functional blocks and network variables to simplify and promote data sharing between like or disparate devices
Provides a network configuration based on functional blocks and configuration properties to facilitate interoperable network configuration tools
Includes a feature-rich type model based on standard and user resource files that expands the market for interoperable devices
Includes an extensive built-in set of I/O objects supporting the powerful I/O capabilities of Neuron processors and smart transceivers
Provides powerful event-driven programming extensions for easy handling of network, I/O, and timer events
