Correlating and visualizing data sampling, current consumption, and program execution via Ozone’s Timeline Window

SEGGER’s J-Trace PRO streaming trace probe and Ozone debugger make a great team. One highlight of this symbiotic relationship is the Timeline window. It allows users to correlate and visualize data sampling, current consumption, and program execution in one combined signal plot. This article takes a closer look at this functionality.

Code size: Closing the gap between RISC-V and Arm for embedded applications

One of the issues faced by RISC-V developers is that the code density of the RISC-V instruction set for deeply embedded processors does not match that of Cortex-M with existing tools. That is changing with the product innovations SEGGER have developed, such as the recently-announced SEGGER Linker, capable of reducing code size by up to […]

Every byte counts – Floating-point in less than 1 KB

How expensive in terms of code size are floating-point operations if the CPU does not have an floating-point unit (FPU)? In this article, I will investigate, based on Embedded Studio for ARM and a generic Cortex-M3 device, how big (or small) an entire application using basic float operations, add, sub, mul, and div, can be. […]

Every byte counts – Smallest “Hello world”

When searching on-line for small C-programs, there seems to be a lot of confusion about what is doable and what is not. There are a lot of posts wondering why even for  minimal programs such as “Hello world” applications are so big, but not many explanations or fixes. I will show how to make a […]

Debugging the dual-core NXP i.MX RT600 with the one and only SEGGER J-Link

The i.MX RT600 MCU family from NXP is an interesting one. Not only do the i.MX RT600 devices feature a 300-MHz Arm Cortex-M33 processor core, but they also include a 600-MHz Cadence Tensilica HiFi4 DSP processor core. This makes the i.MX RT600 devices very suitable for audio playback and voice user interface applications. However, having […]

Extending AppWizard-generated GUIs with emWin Widgets

AppWizard is a great tool for designing GUIs with our emWin embedded graphics library. Features like the intuitive editor, the integrated resource management, and the ability to add behavior to the screen objects by adding interactions make it easy to get started with emWin. But you can create even more advanced graphics solutions by extending […]
