ABSTRACT
Nowadays, with the rapid development of electronic science and technology, a lot of
scientific equipment has been thoroughly modernized, and it is more and more widely used in
real life. What's more, it can be seen everywhere is the support in serial communication. This is
why the use of serial servers is also very widespread, so industrial domain versatility must be
considered as much as possible when developing and researching industrial domains.
This thesis is based on the design and implementation of ARM serial communication, is to
follow up the development of design needs, to study the serial communication, to ensure the
communication needs of all walks of life. In this paper, the serial communication data query, and
then designed a serial communication circuit based on STM32 series monolithic, in the
communication circuit added LED, communication will be flipped flicker. In the process of
communication, the flow lamp circuit and buzzer circuit are added to make the whole design
more intuitive to see and hear the communication process. Finally, the design of the whole serial
communication is completed through the connection of the circuit, the preparation of the program
and the debugging of the circuit, and the debugging results are displayed by the serial debugging
assistant.
This thesis is based on the design and implementation of ARM serial communication. The
first chapter describes the research background, research significance, communication structure,
STM32 serial communication principle.
The second chapter describes the design and implementation of the ARM based serial
communication program analysis, the system function design and draw the system design block
diagram.
The third chapter describes the design and implementation of the ARM based serial
communication hardware design, first of all, the STM32 minimum system is introduced, reset
circuit, crystal oscillator circuit, BOOT selection, power circuit, filter circuit; Communication
circuit USB TO UART; And functional circuit LED&BEE circuit.
The fourth chapter mainly describes the design and implementation of ARM - based serial
communication software design. Design the software for LED, BEE and communication module.
