Engineers across the world building industrial controls, medical devices, and aerospace systems know that they can rely on µC/OS for the foundation of exceptional products.
Real-Time Kernels
µC/OS-II and µC/OS-III
µC/OS-II and µC/OS-III are highly portable, scalable, preemptive, real-time, deterministic, multitasking kernels for microprocessors, microcontrollers and DSPs.
Offering unprecedented ease-of-use, Micrium kernels are delivered with complete 100% ANSI C source code and in-depth documentation. They run on the largest number of processor architectures, with ports available for download from the Micrium Web site.
µC/OS allows you to adjust your system's memory footprint based on your design requirements. And it can be configured to include only those network components necessary to the system, saving valuable memory space.
Communication Software
TCP/IP Networking
A compact, reliable, high-performance TCP/IP protocol stack.
Features dual IPv4 and IPv6 support, an SSL/TLS socket option,
and support for Ethernet, Wi-Fi, and PHY controllers.
USB Device
Real-time USB device software designed for embedded systems. Includes support for Audio, CDC ACM, CDC EEM, HID, MSC, and Vendor classes.
USB Host
Real-time USB host software stack for embedded systems equipped with a USB host or OTG controller. Includes many class drivers (MSC, HID and CDC ACM).
CAN Bus
A CAN protocol framework that enables easy and clean implementation of CAN communication paths. Optimized for speed, flexibility and size, and high portability.
Modbus
An industrial communications protocol used for connecting industrial electronic devices. Scalable, works with any CPU, and supports any number of communications channels.
Storage & Display Software
File System
A compact, reliable, high-performance and thread-safe embedded file system for microprocessors, microcontrollers and DSPs. An optional journaling component provides fail-safe operation, while maintaining FAT compatibility.
Graphical User Interface
A flexible graphical user interface for any embedded application that requires a graphical display. µC/OS allows you to produce fantastic user interfaces for your device using a graphical LCD display. It can be as simple as a 2D graphic with monochrome color up to smartphone like graphics with 32 bits per pixel color. With touch screen support activated, you can really provide products with state of the art user interfaces.
