Simplifying software development for connected applications has become more important as the Internet of Things (IoT) continues to encompass a greater range of everyday products. Texas Instruments (TI) announced key updates to its complete real-time operating system (RTOS), which brings the ease-of-use associated with power management operations in high-level operating systems, such as Android and Windows, to embedded microcontroller (MCU) – based applications. As a result, using TI-RTOS 2.12, developers can easily leverage the power management features built into TI devices to create IoT applications with a longer battery life. Intended for use across TI’s entire embedded processing portfolio, TI-RTOS 2.12 is free and enables developers to focus on application differentiation and faster time-to-market with pre-built and tested connectivity stacks and drivers, eliminating the need to write low-level code. This new version of RTOS is a major update to the platform that was first introduced in 2012 and leverages more than 20 years of TI’s experience in delivering production-quality OS solutions for real-time applications.

TI-RTOS 2.12 provides a standard set of multitasking, power management and peripheral driver APIs across all supported devices. This allows developers to easily port applications between different TI MCUs running TI-RTOS, reducing development time of next-generation products. The updated platform also benefits TI Design Network software members by providing a free, widely used software platform without proprietary constraints.

TI-RTOS 2.12 is now integrated with the Energia development environment. Energia and Arduino are based on the Wiring framework and allow developers to rapidly prototype applications without having extensive embedded experience. This integration of TI-RTOS 2.12 combines Energia’s familiar and easy-to-use APIs with new unique features, such as multi-threading. This is an easy way to start making multi-threaded applications on TI’s low-cost LaunchPad development kits, while leveraging the familiar hardware abstraction layer.

TI-RTOS 2.12 features and benefits

  • Enables longer battery life through TI-RTOS’ power management features, which allows developers to achieve aggressive power savings for their applications with minimal effort.
  • Broad range of wireless connectivity options, including Wi-Fi®, Bluetooth® Smart and ZigBee through integration with on-chip stacks available using TI’s SimpleLink™ Wi-Fi CC3100/CC3200 solutions and SimpleLink CC26xx/CC13xx ultra-low power wireless MCUs.
  • Open-source (BSD) licensing for OS components and drivers, which enable easy and free deployment for any application.
  • Decreases development time by using an extensive base of preexisting software libraries to eliminate building software from the ground up.
  • Robust documentation and an extensive set of examples, which allow developers to quickly evaluate TI-RTOS capabilities and begin development.


TI-RTOS 2.12 is available today and supports all TI devices aimed at low-power IoT applications, including TI’s new 32-bit MSP432™ MCUs, TI’s SimpleLink Wi-Fi CC3100/CC3200 solutions and SimpleLink CC26xx/CC13xx wireless MCUs. It also supports the TM4C MCUs, C2000™ real-time control MCUs and Sitara™ processors. TI will continue to expand its RTOS offering to other MCU and processor families.

TI’s Design Network: What our partners are saying about TI-RTOS 


“We are excited to see what developers of all experience levels will make now that we have combined the ease-of-use of the Energia and Wiring framework with the power of TI-RTOS 2.12,” said Robert Wessels, founder of Energia. “With the introduction of multi-threading, developers will be able to solve new problems that were not possible in a traditional single-loop sketch.”


“We have supported TI-RTOS and its predecessors for many years with our embedded middleware solutions, including a comprehensive range of truly fail-safe file systems supplied with drivers and a validation test suite for NAND, NOR, eMMC and other popular flash technologies,” commented David Brook, director of marketing at HCCEmbedded. “Our networking software, developed using a verifiable process to minimize risk, provides another option for customers building secure network applications.”

InterNiche Technologies 

“Working with TI has enabled us to offer a pre-ported version of our NicheStack SNMP, which supports SNMP v1/2/3 for TI-RTOS 2.12 that saves development time and energy,” commented Larry Larder, president of InterNiche Technologies. “Our collaboration with TI through the years allows us to offer a broad range of embedded protocol modules, including NicheStack HTTP, SSL/TLS 1.2, IPSec and SNMP.”

Simma Software 

“The ease of integration, reliability and performance that we have been able to deliver to our customer base with our CAN solutions offerings in combination with the upgraded TI-RTOS 2.12 is just another reason why we recommend TI and their solutions to our customers,” said J.R. Simma, founder and director of engineering, Simma Software, Inc.
