Hello, friends! Today, I want to introduce you to a recent “black technology” that has been gaining popularity—MuditaOS. This name might sound a bit unfamiliar, but its capabilities should not be underestimated! If you appreciate simplicity and purity, and want to avoid being overwhelmed by notifications and ads, you definitely need to learn about this … Read more
Embedded systems are becoming smarter, more interconnected, and certainly more complex than ever before. To keep embedded systems robust and as error-free as possible, development teams need effective methods for testing and validating that the system works as intended. The most critical and often the most challenging aspect of testing is running software on microcontrollers. … Read more
Kunvar Chokshi is an embedded development engineer with over ten years of embedded experience. The Edian team provided the translation. Embedded developers typically start their projects in the bare metal domain—without an operating system, no multitasking, just raw code running directly on the hardware. This approach is all about direct register manipulation and peripheral control … Read more
One of the core tasks of an operating system is task scheduling. Tasks have different names in different operating systems, such as task, thread, or process, with processes typically associated with independent address spaces. The goals of scheduling are to ensure fairness, real-time performance (for real-time systems), maximize CPU utilization, and meet task priority requirements. … Read more
