1, Basic storage unit bit: A digit in a binary number, which can be 0 or 1. It is the smallest unit of data in a computer. Byte s: The basic unit of data in a computer. Every 8 bits form a byte. All kinds of information need at least one byte to be stored and processed in the computer. For example, an ASCII code is represented by one byt ...

In the "message queue" article, we once buried a foreshadowing, that is, the message delivery and synchronization of tasks in FreeRTOS are all through message queue. Can't it be through global variables? The answer is yes, but this will cause delayed response. If you use global variables, you can only poll, which will inevitably lose ...

0. Write in front The main purpose of this article is to describe how to make the ESP32 chip run JavaScript and let the web front-end developers play with the hardware. The author was a web front-end development engineer before, so the article will try to stand in the perspective of Web front-end development engineer, put aside the underlyin ...

1. Preface FATFS tutorials and processes are common, and its platforms cover from 8051 core MCU to Cortex-M7 core high-performance MCU and even higher performance application processors. However, most STM32 tutorials and routines bypass this mode using D-Cache writeback mode and DMA. For example, the processes of punctual atoms and wildfire ...

Hello, everyone. I'm surprised. Let's talk about string today. There are many scenarios for using strings, which are used in human-computer interaction and dual computer communication. For example: Send instructions to MCU through serial port to perform operation or configure parameters.MCU reads sensor data, and the data format is string. Gen ...

This article is based on the wildfire guider F103 onboard LCD screen control, if there are any inaccuracies, welcome to refer to the orthogonal flow! Preface This article first briefly introduces the principle and initialization of STM32 external interrupt EXTI and LDV5 voice module, then uses external interrupt EXTI to control the on-b ...

1, W5500 module 1. Introduction to w5500 Ethernet module (1)D-W5500 EVB Ethernet module is an Ethernet module based on WIZnet W5500 chip with high cost performance. W5500 is a full hardware TCP/IP embedded Ethernet controller, which provides a more recommended Internet connection scheme for embedded systems. (2)W5500 solidifies the TCP/IP ...
