This embedded system specifically refers to those based on the Linux platform; microcontrollers and other RTOS are not discussed. I have been engaged in embedded software development for 6 or 7 years, involving BSP, drivers, application software, Android HAL, frameworks, etc. Besides focusing on the development of the embedded industry, I also pay some attention … Read more
Embedded systems are divided into four layers: hardware layer, driver layer, operating system layer, and application layer. 1. Hardware Layer The hardware layer is fundamental to the entire embedded system. If you are familiar with microcontrollers and interfaces, and can program in C and assembly language, starting from the hardware layer of embedded systems is … Read more
1. Introduction Embedded systems are a branch of software design, and their various characteristics determine the choices of system architects. At the same time, some of their issues have considerable universality and can be extended to other fields. When it comes to embedded software design, the traditional impression is microcontrollers, assembly language, and a high … Read more
