Problems solved by technology

Due to the single function of the traditional single-chip microcomputer, it often cannot meet the requirements, or even if it can be realized, it needs to use a large number of MCUs to work together, and it will encounter considerable difficulties in signal connection, programming and volume reduction.
It is very difficult to develop, maintain and expand the front-end and back-end systems directly on the bare metal, and such a system is essentially a program hypercycle, which cannot guarantee the real-time requirements of the measurement and control system.
