Learning SCM is of great help to society

51 SCM is compatible with all Intel 8031 The general designation of the single chip microcomputer of the instruction system . The ancestor of this series of single chip computers is Intel Of 8004 Single chip microcomputer , Later, along with Flash rom Development of technology ,8004 MCU has made great progress , Become the most widely used 8 One of the single chip computers , Its representative model is ATMEL The company's AT89 series , It is widely used in industrial measurement and control system . Many companies have 51 Series of compatible models launched , In the future, it will occupy a large number of markets for a long time .51 SCM is a basic SCM , Or the most widely used one . It should be noted that 51 Series of microcontrollers generally do not have self programming ability .

It's been a while since the company left , At present, I am still resting and thinking at home , Before, because I was leading the team , It's not very convenient to answer the salary question positively , Here is a brief discussion with you .

The current employment situation in the embedded industry is not bad , In addition to the slightly declining mobile phone industry , Large screen of cars and electric bicycles 、 Charging pile 、AIoT、 All kinds of learning machines 、 Intelligent Watch 、 Intelligent speakers 、 Video surveillance 、 Sweeping robot 、 Chip development 、 Cloud computing, virtualization and other fields all need  Linux Classmate .
