C2 SDK

C2 SDK(VistaCube™) supports two essential functions: Flash memory programming (burning) and display control via host software, such as firmware or operating systems. It is designed to work seamlessly with RAONTECH’s RDCx00 and RDCP340X series, which require the latest flash memory image for proper operation. This includes internal MCU firmware, RDC/RDP initialization data, LUTs, and Gamma correction data.

VistaCube™ provides a streamlined and reliable way to manage and update these flash image components, whether stored in internal or external Flash memory. It simplifies what is typically a complex process, making it easier for developers to maintain firmware consistency across different platforms.

The VistaCube SDK includes not only the core source code but also practical example software tailored for various platforms — including stand-alone firmware for microcontrollers, Android, and Windows. Additionally, RAONTECH provides porting guides and integration tips on its official blog, covering the following environments:
• Stand-alone firmware for MCU
• Linux, Android, and Windows OS

With VistaCube™, developers gain both flexibility and control across the full development lifecycle — from initial firmware flashing to real-time display management.
