1. What is the difference between Arduino and Embedded C?
The main differences between Arduino and Embedded C are their application scenarios, development difficulty and hardware design. Arduino is more suitable for rapid prototyping and teaching, while Embedded C is suitable for scenarios that require high performance and professional applications.
Arduino is an open source hardware platform mainly used for rapid prototyping and teaching. It uses high-level programming languages such as C++ and provides an easy-to-use development environment, allowing beginners to quickly get started and implement projects. In contrast, embedded C is often used in high-performance and professional application scenarios, such as industrial control, automotive electronics and other fields. Embedded C programming usually involves low-level hardware knowledge and more complex programming skills. The language used may be C or C++, but memory and hardware resources need to be managed manually. -
2. Is Raspberry Pi a microcontroller?
Raspberry Pi is not a microcontroller in the traditional sense. Raspberry Pi is a microcomputer, often called a single-board computer, which has more powerful computing power and more functions, including writing code directly on the device and running multiple programming languages.
Raspberry Pi has some features of a microcontroller, such as it also has GPIO (general input and output) pins, which can control external devices through these pins. In addition, Raspberry Pi can also be used for the development of embedded systems, especially in application scenarios that require higher computing power. -
3. What is STM32 embedded?
STM32 is a microcontroller suitable for control applications. It comes with various commonly used communication interfaces, such as USART, I2C, SPI, etc., and can control a variety of devices. In real life, many electrical products we come into contact with have STM32, such as smart bracelets, micro quadcopters, balance cars, mobile POS machines, smart rice cookers, 3D printers, etc.
An embedded system is a special computer system centered on applications, based on computer technology, and with customizable software and hardware. It requires small size, high reliability, low power consumption, and stable performance. The embedded system is divided into hardware layer, driver layer, operating system layer, and application layer. The hardware layer is the foundation of the entire system. The driver layer needs to write a driver program to enable the hardware to communicate with the operating system. The operating system layer is responsible for task scheduling and management, and the application layer is the interface and function implementation for direct user interaction. -
4. What language is used for embedded microcontroller programming?
The main languages used for embedded microcontroller programming include C, C++, assembly language, Python and Rust. These languages have their own characteristics and are suitable for different development needs and scenarios.
C is one of the most commonly used languages in embedded development. It has the advantages of high efficiency, flexibility, and strong portability. It can directly operate hardware and is suitable for low-level driver development, kernel programming, etc. C++ is used in complex embedded systems and adds object-oriented features, which is suitable for the development of large applications. Although assembly language is difficult to learn and write, it is indispensable in scenarios that require high optimization and direct control of hardware. Python is easy to learn and use, and is often used in data processing, prototype development, and rapid testing. Rust is gradually gaining attention in the embedded field due to its memory safety and high performance, especially in applications with high security requirements.
