I get busy as soon as I arrive at the office every day. I need to wash my cup, choose the tea I brewed today, then go get hot water, tidy up my desk, charge my phone, turn on the computer, check today’s work tasks, browse the work group, and then I feel tired. I … Read more
When debugging with RTOS, CLion provides views for FreeRTOS, Azure RTOS, and Zephyr tasks (threads). For FreeRTOS, you can also explore objects and the heap. Some gdb servers have built-in support for different RTOS. To ensure proper integration with CLion, make sure to disable built-in support on the gdb server side. To enable the RTOS … Read more
In the previous article, we used FreeRTOS to light up an LED, which essentially got FreeRTOS running. To effectively use an RTOS, it is necessary to understand how the scheduler works from a black-box perspective. Of course, if you want to study its internal implementation, you can read the source code. However, I feel that … Read more
Abstract：We encounter many operating systems, such as Windows, Android, iOS, and Linux, which are all types of operating systems. Microcontrollers also have their own operating systems, known as real-time operating systems. So what are the differences between these real-time operating systems and the systems we use? The operating systems we commonly use are actually non-real-time … Read more
1. Concept Introduction 1.1 What is the Boot Process of a Microcontroller? The boot process of a microcontroller refers to a series of initialization steps that occur from the moment power is applied or the device is reset until the user code begins execution. Different microcontrollers have specific details in their boot processes, but most … Read more
Enable the multi-core functionality of the ESP32 to execute tasks in parallel while setting the chip’s clock frequency and the FreeRTOS real-time system. The effect achieved in this article is shown in the GIF, where two displays execute in parallel, each using one of the ESP32’s two cores. The display of the two screens, if … Read more

What is an Embedded System? An embedded system is a dedicated computer system designed for specific applications, based on computer technology, and customizable in both hardware and software. It is typically embedded within other devices or products to control, monitor, or perform specific tasks. Examples of applications for embedded systems include controllers in smartphones, automotive … Read more
1 FreeRTOS Since RTOS requires a certain amount of system resources (especially RAM), only a few real-time operating systems such as μC/OS-II, embOS, salvo, and FreeRTOS can run on small RAM microcontrollers. Compared to commercial operating systems like μC/OS-II and embOS, FreeRTOS is a completely free operating system, featuring open source code, portability, scalability, and … Read more
