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
