C language is used in this design, which has the characteristics of being able to implement structured programming language, high readability and easy to transplant to other devices, and also has detailed hardware control instructions with bit operation function. You can also use structures and arrays to process complex data.The software programming of this system uses the software development system of Keil C51 C language. The software has very practical library functions and powerful The main program design part mainly completes the initialization of the system, data collection and the task of calling each subroutine module as needed, and forms an organic and unified whole.
