Extended data;

Embedded system is application-centered, based on computer technology, and its software and hardware can be tailored, which is suitable for special computer systems with strict requirements on function, reliability, cost, volume and power consumption. It is generally composed of embedded microprocessor, peripheral hardware devices, embedded operating system and user applications, and is used to control, monitor or manage other devices.

An embedded software engineer is an engineer who writes embedded systems.

Requirements;

1. The most important thing is C language programming and C++, which has a lot to do with your study, application, development projects and system transplantation.

2. Operating system: LINUX, WINCE, etc. I have studied at least one and need to know a lot of basic knowledge;

3. Familiar with hardware such as ARM, FPGA and DSP.
