Day 66: ABI Compatibility in C Language In the previous lecture, we analyzed the issues and best practices of dynamic loading libraries (such as dlopen), including the dynamic loading process, common pitfalls, and safe coding paradigms. 1. Step-by-step Explanation of the Theme Principles and Details ABI (Application Binary Interface) determines how different binary modules (such … Read more
The Awakening of the “Silent Giant”: The Quiet Comeback of the Windows ARM Ecosystem Once upon a time, when mentioning the Windows ARM platform, most users might associate it with tags like “poor compatibility” and “mediocre performance.” Even though Microsoft ambitiously launched devices like the Surface Pro X, this platform seemed to linger outside the … Read more
1. The wiring between RS-232 and TTL mainly involves voltage conversion, as RS-232 uses negative logic levels (+3V to +15V represents logic low, -3V to -15V represents logic high), while TTL uses positive logic levels (0V represents logic low, 3.3V or5V represents logic high).When no data is transmitted on the serial data line, it is … Read more
The Octal interface protocol typically refers to Octal SPI (Serial Peripheral Interface), which is an extension of the SPI standard used for high-speed data transmission between microcontrollers and external devices. Below is a detailed introduction: Basic Concept: Octal SPI, also known as “8-line serial interface” or “8-bit SPI,” uses eight data lines for parallel data … Read more

It aims to provide a simple, fast, and memory-efficient way to store and transmit data structures such as dictionaries, lists, integers, floating-point numbers, strings, etc., serving as a lightweight alternative … Read more
Dear friends, the Bluetooth in today’s smart cars has truly become a situation where “it takes a minute to connect after getting in the car, and your phone is slower than the car itself”. You get into a new car with excitement, but then you have to wait for the Bluetooth to connect to the … Read more
In the world of 3D printing, hardware varies greatly, with a wide range of motherboards and inconsistent protocol standards. Achieving harmonious coexistence among all devices is not an easy task.Compatibility differences and configuration complexity have become the biggest obstacles to the widespread adoption of 3D printing. The emergence of Marlin firmware has completely changed this … Read more
