Many of you may have heard of or used the tool SystemView. It is a tool for online debugging of embedded systems, capable of analyzing which interrupts and tasks are executed in an RTOS, as well as the sequence of these interrupts and tasks. It also allows you to view the timing of kernel object … Read more
In the era of big data, how do embedded systems cope with massive data streams? In embedded system development, we often face the dilemma:interrupt service routines need to quickly process input data, whileapplications need to reliably and stably consume this data. The mismatch in speed between the two often leads to data loss or system … Read more
From RT-Thread to FreeRTOS: Why I Decided to Start a New Learning Journey Hello everyone! Recently, many friends have asked me: “Haven’t you already learned RT-Thread? Why do you want to learn FreeRTOS?” Today, I want to discuss this topic and also announce that I will be updating my FreeRTOS learning notes from time to … Read more
Why Do MCUs Need an Operating System? Starting the RT-Thread Learning Series! Introduction If you are a microcontroller developer, you may have this question: Isn’t bare-metal development sufficient? Why should we install an operating system on a small MCU? Today, we will discuss this topic and embark on the journey of learning RT-Thread! 1. Why … Read more
The title of this project is: Rock-Paper-Scissors Gesture Recognition. This project implements basic gesture recognition for rock-paper-scissors, compares the recognized results with the gestures stored in the machine, controls the servo’s behavior based on the results, and synchronizes the recognized results to the host computer. Table of Contents Project Overview Hardware List Servo Control Pins … Read more
