C4 SDK

The C4 Software Development Kit (SDK) is an advanced and exclusive development platform designed specifically for RAONTECH’s C4 controllers. Built to support high-performance augmented reality systems, the C4 SDK offers comprehensive tools for both flash memory management and real-time display control, tightly integrated with RAONTECH’s hardware ecosystem.

To ensure stable and accurate operation, the C4 SDK provides an efficient process for managing and updating the required flash image components. These include:
• Internal MCU firmware
• RDC/RDP initialization data
• LUT (Look-Up Table) configuration

These image components can be programmed into internal or external flash memory, enabling developers to maintain consistent system behavior throughout the product lifecycle.

The SDK includes:
• Core source code optimized for C4 hardware
• Example software for quick prototyping and integration
• Multi-platform support for stand-alone MCU firmware, Android, and Windows

RAONTECH also provides practical porting guides and integration documentation through its official blog, supporting rapid adoption and development.
