Lightweight Embedded System Framework: mr-library Overview

Introduction to mr-library

mr-library is a lightweight framework for embedded systems that provides a unified low-level driver device model and basic service functions. It features modular design, configurability, and extensibility, helping developers quickly build embedded applications.

The mr-library framework supports basic kernel functions such as mutexes and object management. It integrates asynchronous event-driven frameworks (events), multi-timer software timers (soft-timer), and other services. It provides driver device models for common peripherals such as serial ports, SPI, I2C, ADC/DAC, allowing access to underlying hardware

Custom Communication Protocol for Intelligent LCD Display Module HMI

1. HMI and Communication Protocol
With the development of industrial technology, the application field of HMI (Human-Machine Interface) is becoming increasingly broad. The custom communication protocol implemented by Topway's intelligent LCD display module can maintain the confidentiality of enterprise data to a certain extent, enhance the diversity of product functions, and solve the problem of incompatible communication protocols.
The serial communication rules for HMI, except for standard Modbus protocol products, are mostly based on the protocol rules set by the original manufacturer.

Why is the ESP32 So Popular?

❝
The ESP32 is something many people may have heard of or used. If you have previously used an Arduino development board, you might have come across it as well. The ESP32 refers to a series of chips and modules produced by Shanghai Espressif Systems, rather than a specific chip, which is something to note. Today, I will introduce Espressif's chips.
Espressif's Chip Family
Espressif has five system products, namely: ESP32S series, ESP32C series, ESP32H series,ESP32, and ESP8266 (Yes, except for the ESP8266,
