emPower OS Object Code

emPower OS is a high-performance software platform for embedded systems and Internet of Things (IoT) devices. It is optimized for a small memory footprint and easily fits onto typical microcontrollers without requiring external memory. It includes RTOS, GUI, file system, TCP/IP, USB host/device, Modbus, IoT tools, encryption, SSH, TLS, and compression.

Its free for non-commercial-use form is made available within Embedded Studio PRO.

Embedded Studio

The leading cross platform IDE Embedded Studio is the complete all-in-one solution that provides a continuous workflow for managing, building, testing, and deploying embedded applications.

This includes project manager, source code editor, an integrated debugger, J-Link integration, and version control.


SystemView is a tool for real-time recording and visualization of events and interrupts while the system is running. The recorded data is analyzed and the system behavior is visualized in different views.

SystemView can ensure a system performs as designed, can track down inefficiencies, and show unintended interactions.

Ozone – J-Link Debugger

Ozone is the debugger for J-Link and J-Trace. It includes all well-known debug controls and information windows and makes use of the best performance of J-Link and J-Trace debug probes.

Ozone provides full system insight, to track down inefficiencies and bugs, and to make your products even better.
