Since January 15, NVIDIA released the upgraded Jetson NANO development kit, we finally got the physical product today, four days later. I’m sure some users are asking: How do I know if I bought the first or second generation? Look at the outer packaging: Let’s take a look at the physical product: The second generation … Read more
iNature Intense noise can damage the spiral ganglion neurons (SGN) in the inner ear, affecting axonal regeneration and leading to noise-induced hearing loss (NIHL). On November 19, 2024, researchers from Fudan University, Bu Wenbo, Ren Dongdong, and Liu Yanyan published a paper titled“Ultrasound-Triggered NO Release to Promote Axonal Regeneration for Noise-Induced Hearing Loss Therapy” in … Read more
Click on the arrow“blue text”, follow us! Californium (Cf): Java’s CoAP Protocol Library! Hello everyone, I am Niu Ge. Today we will talk about a “chemical element” in the Java IoT world— the Californium framework. Don’t be scared by its name; this is not a chemistry experiment, but a powerful and practical CoAP protocol framework. … Read more
Introduction RAM is the component in a computer system that stores temporary results, and its size also determines the scale of data processing by the computer. In embedded computers (microcontrollers), due to factors like cost and power consumption, the internal RAM capacity is often quite small, typically ranging from a few hundred bytes to several … Read more
dATa: Fixed to the first 128 RAM addresses from 0x00 to 0x7F, can be directly read and written using ACC, fastest speed, and generates the smallest code. iDATa: Fixed to the first 256 RAM addresses from 0x00 to 0xFF, where the first 128 are identical to dATa, but accessed in a different way. iDATa is … Read more
Previously shared the article “What Features Were Updated in FreeRTOS V10.4.0?” and today we will elaborate on one of the knowledge points: FreeRTOS’s direct task (message) notification, aimed at reducing RAM usage and speeding up execution. 1. Introduction Almost all RTOS operating systems provide queue and semaphore functionalities, which are essential skills for most beginners. … Read more
You must be curious: mobile phone memory (RAM) often reaches 8G or 12G, but why do microcontrollers have less than 1M of RAM? To understand, the classic AT89C51 microcontroller has only 128 bytes of RAM (memory). Similarly, the classic MSP430F149 also has only 2K of RAM space. Even the STM32F1 series, which is commonly used … Read more
Previously, I wrote a few examples of how to use C# to write STM32 programs. Similarly, we can also use C# under ESP32, relying on the ever-growing .Net nanoFramework. Currently, it supports more and more development boards and chip types, and the related libraries are also increasing. The supported devices can fully support conventional application … Read more
This article will introduce how to create a wake-on-LAN device using ESP32 hardware and implement the WOL (Wake-on-LAN) function through .Net nanoFramework, sending WOL packets to wake up remote computers. 1. Background In previous articles, we introduced how to use libraries related to .Net nanoFramework to achieve various functions, such as reading sensor data, controlling … Read more
