介紹了基于單片機(jī)C8051f020的通用串口適配器的設(shè)計(jì)與實(shí)現(xiàn)方法，即由單片機(jī)控制的智能化一對(duì)多口收發(fā)信號(hào)轉(zhuǎn)換器。通過(guò)采用C51對(duì)單片機(jī)進(jìn)行編程，控制與RS-232（標(biāo)準(zhǔn)RS-232電平）、RS232(TTL電平)、RS-422接口的數(shù)據(jù)通信；采用C++ Builder作為開(kāi)發(fā)平臺(tái)，通過(guò)RS-232接口實(shí)現(xiàn)上位機(jī)對(duì)適配器各個(gè)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.
