When we talk about video games on an oscilloscope, you’d be pardoned for assuming the project involved an analog CRT scope in X-Y mode, with vector graphics for something like …read more Continue reading Tetris on an Oscilloscope, the Software Way
Most of the computers we interact with on a day-to-day basis use an operating system designed for flexibility. While these are great tools for getting work done or scrolling your …read more Continue reading Tiny Microcontroller Uses Real-Time Operating System
When debugging something as involved as kernel scheduler timings, you would typically use one of the software-based debugging mechanisms available. However, in cases when software is close to bare metal, …read more Continue reading How Realtime Is Your Kernel? Scope A GPIO To Find Out
Researchers have unearthed 13 vulnerabilities affecting the Nucleus NET TCP/IP stack and have demonstrated how attackers could exploit them to cause serious real-world damage. The good news is that Siemens – the current owner of the stack –… Continue reading Vulnerabilities in Nucleus NET TCP/IP stack could lead to real-world damage
When do you need to use a real-time operating system (RTOS) for an embedded project? What does it bring to the table, and what are the costs? Fortunately there are strict technical definitions, which can also help one figure out …read more

One of the goals of programming languages back in the 1950s was to create a way to write assembly language concepts in an abstract, high-level manner. This would allow the same code to be used across the wildly different system architectures of that era and subsequent decades, requiring only a …read more
