1. What is an embedded microcontroller?
An embedded microcontroller is a device that integrates an entire computer system into a single chip. It usually includes functional modules such as a central processing unit, memory, input and output ports, and timers, all of which are integrated on a single chip. This design enables embedded microcontrollers to perform specific tasks with high flexibility and efficiency.
The main features of embedded microcontrollers include:
Highly integrated: multiple functions such as CPU, memory, and I/O interface are integrated on a single chip, reducing the number of components and system volume.
Strong specialization: Optimized for specific application scenarios, providing a specific combination of processing power, memory, and input and output interfaces.
Efficient and reliable: The integrated design makes the system more stable and reliable, reducing the connection of external components and signal interference.
High flexibility: According to different application requirements, embedded microcontrollers can have multiple derivative products, each with the same processor core, but different memory and peripheral configurations to adapt to different application scenarios. -

4. 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.
