To learn embedded development, you need to master the following knowledge and skills:
1. C/C++ programming language: Embedded systems usually use C/C++ as the main programming language, and you need to be familiar with the syntax, data structures, and algorithms of these languages.
2. Hardware knowledge: Understanding electronic components, circuit design, and digital circuitry fundamentals is the foundation of embedded development. You need to learn how to read and understand circuit diagrams, and master basic circuit design principles.
3. Microprocessors and microcontrollers: Understand the architecture, characteristics, and programming styles of various microprocessors and microcontrollers. Familiarize yourself with common processor architectures such as ARM, AVR, etc.
4. Embedded System Architecture and Operating Systems: Learn the basic architecture and working principles of embedded systems, and understand the use and management of real-time operating systems (RTOS).
5. Interfaces and communication protocols: Familiarize yourself with various common interfaces and communication protocols, such as UART, SPI, I2C, Ethernet, etc., as well as related communication protocol stacks.
6. Embedded development tools and debugging skills: master the use of embedded development tools and debuggers, such as compilers, debuggers, emulators, etc., as well as related debugging skills and methods.
7. Internet of Things (IoT) and wireless communication: understanding of IoT technologies and wireless communication protocols such as Wi-Fi, Bluetooth, LoRa, etc. for embedded system connectivity and communication.
In addition to the core knowledge and skills listed above, it is recommended that you gain an in-depth understanding of the application areas of embedded systems, such as automotive electronics, industrial controls, medical devices, etc., in order to better understand the specific needs and challenges of embedded development.
