Espressif Systems It is said that shareholders of 688018 are paying attention Kanazawa Institute of Technology in Japan has introduced the micro-drone development platform StampFly, launched by M5Stack (a subsidiary of Espressif), into its control technology and programming courses. This device is based on the Espressif ESP32-S3 chip and combines ESP-NOW wireless communication technology, providing … Read more
Recently, I came across an open-source project called meshtastic. It primarily builds a decentralized network using LoRa spread spectrum communication. In China, it is likely more suitable for mountainous areas and rescue communication scenarios, as we can make phone calls as long as we are not deep in the mountains. This project mainly uses the … Read more

On March 10, according to EEnews Europe, researchers in Spain discovered hidden instructions in a low-cost microcontroller from Espressif, making it vulnerable to attacks. This microcontroller has been widely used in the Internet of Things (IoT). The team from Tarlogic Innovation in Madrid demonstrated a study showing that the Espressif ESP32 integrated Bluetooth microcontroller (MCU) … Read more
In the embedded field, embedded real-time operating systems are becoming increasingly widely used. Using an embedded real-time operating system (RTOS) can more reasonably and effectively utilize CPU resources, simplify application software design, shorten system development time, and better ensure the system’s real-time performance and reliability. FreeRTOS is a mini real-time operating system kernel. As a … Read more
Recently, a reader asked the following question: Why is the default configuration for the RTOS system tick (Tick) set to 1000? Can I configure it to 100, 10000, or 2000? Many beginners have this question, including myself when I first learned about RTOS. I was confused about what the different tick configurations meant and their … Read more
