介紹了基于單片機C8051F020的通用串口適配器的設計與實現方法，即由單片機控制的智能化一對多口收發信號轉換器。通過采用C51對單片機進行編程，控制與RS-232（標準RS-232電平）、RS232(TTL電平)、RS-422接口的數據通信；采用C++ Builder作為開發平臺，通過RS-232接口實現上位機對適配器各個通信端口的控制。
Abstract:
Design and realization of a universal serial port adapter based on the MCU C8051F020 are introduced.The adapter is an intelligent one-to-more receiving and transmitting signal converter controlled by the MCU. By programming the MCU with the language C51,MCU control data communication between the MCU and RS-232(RS-232 level),RS-232(TTL level),RS-422 port; Using C++ Builder as the development plane, by one RS232 port, the upper PC can control each of the communication port of the adapter.
