The development of embedded systems requires profound knowledge of hardware and software, because they need to control equipment under strict resource constraints. Hardware engineers need to design circuit boards and components, while software engineers need to write the code of embedded systems. The software of embedded system usually needs to be efficient, reliable and safe, because they must run on the device for a long time.
The successful development of embedded systems requires system-level thinking because they represent a complete system. This means that developers need to consider all aspects of the system, such as power consumption, performance, reliability and security. The development of embedded system needs to follow a certain development process, including requirements analysis, design, implementation, testing and deployment.
The development of embedded system also needs a deep understanding of the underlying hardware and software, such as processor, operating system, programming language, compiler and so on. In addition, developers need to understand various communication protocols and standards, such as UART, SPI, I2C, TCP/IP, etc. For some applications, you need to know the specific processor architecture and instruction set.
In a word, embedded is an interdisciplinary subject involving hardware and software, which requires developers to have deep knowledge of software and hardware and system-level thinking. The development of embedded system needs to follow a certain development process and deeply understand the underlying hardware and software in order to realize an efficient, reliable and safe embedded system.
