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 .
Overall treatment of Embedded Industry , Put aside those special cases ( Cash out of listed stocks 、 Excessive profits, dividend bonus 、 Start your own business and be the boss 、 Dr. Huawei et al ), It is understood and observed , The general situation of the industry is as follows ( There will be certain differences in the industry , The following is just a reference bandwidth , Not absolute ; In addition to the basic monthly salary , Generally, there will be supporting five insurances and one fund , Pay attention to the difference in points ,1 The year-end bonus from three months ):
Just graduated , There is a certain Linux Basics , Undergraduate and graduate students in 8~ 10k rise .
graduation 1~3 year , Basically, you should be able to undertake a certain work independently ,9k~20k rise .
graduation 3~5 year , Being the backbone of a certain field also has the ability to guide new people ,15k~30k rise .
graduation 5~10 In the above , Acquire the , Become an expert in one or more fields , Be able to establish a technical system , It has a certain industry influence , Be able to lead the organization to solve major and difficult problems ,20k~50k, Some enterprises may be 20~30k The above adopts the way of annual salary package , With a low monthly salary + Performance year end (2~ Several months ~ Dozens of months ) How to pack , So that everyone can continue to take the initiative 996 Go to “ Beyond oneself ”, Achieve better performance .
Here are some important contents :
1. About working status . Insist on working with the mentality of entrepreneurs , Don't feel like a wage earner . It's not just about doing the tasks assigned in the project , Actively seek to make products , At the same time, exercise yourself .
2. About salary adjustment . A well-defined enterprise , If it's good enough , Willing to take the initiative to help others , Willing to share and participate , And have basic EQ , Get 10%,20%, Even outstanding and the enterprise is not in a dead and dying state , Get 30%,50% There are opportunities for the above increase . however , Most of the students may be 5%~20% About . therefore , If you want to get a good salary increase , Beyond the efforts of ordinary people is the first , Another is that enterprises must have supporting measures . If you try , Enterprises do not have a good supporting environment ( For example, there is no new business , Products can't sell well , It's hard to change in the short term , Or the personnel and salary system is terrible ),2~3 Please consider job hopping around the year .
3. About career planning . There must be planning , What state do you want to achieve in a few years after graduation , What company , what title/ Rank , What salary , Every year, we will move forward towards the preset goal , Go all out .
4. About skill improvement . Participate in enterprise induction training , Participating in the actual combat of the project is basic , Good companies will have supporting induction training programs , Including corporate culture and skill training , There will also be instructors , Or invite external lecturers to teach , Or organize external lectures and training , Another is that there are enough challenging projects to practice . If none of this , And there is no business to do , Doing nothing all day long , Then consider changing the company , Don't wait to die .
5. Personal promotion plan . besides , You must have your own clear promotion plan , Expertise ( The basic principle of vertical depth 、 A broad and systematic knowledge map 、 Practical tools and skills 、 Industry development trend ), Speaking ability , Ability to collaborate , The ability to guide others , Project organization and management ability , Industry exchanges , Technology frontier , You can actively seek opportunities in the project , Self study , You can also participate in various technical salons , Industry Summit , Or training organized by enterprises and third parties .
While thinking at home recently , On the one hand, do open source projects , On the other hand , I'm also thinking about how to present some personal growth experiences and industry observations in some way , In order to help more students in the confused period take fewer detours .
