So far, China's single-chip microcomputer application and embedded system development have gone through more than 20 years. With the embedded system gradually going deep into all aspects of social life, the teaching of single-chip microcomputer scheme course also tends to change from the traditional 8-bit processor platform to the 32-bit Advanced RISC processor platform, but the 8-bit processor is still difficult to be replaced. National economic construction, military and household appliances and other fields, especially mobile phones, auto navigation equipment, PDA, smart toys, smart appliances, medical equipment and other industries, are industries in urgent need of MCU talents in China. At present, there are more than 100000 engineers engaged in the development and application of single chip microcomputer in the high-end industry. However, facing the trend of embedded system industrialization and the opportunity of vigorously promoting the construction of "embedded software factory" in China, China's embedded products will be in urgent need of a large number of single chip microcomputer application talents in order to integrate into the international market and form an industry, This provides a great opportunity for higher vocational students to engage in this kind of high-tech industry.
