3. 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. -
4. 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.
