基于CH341A的USB串口通訊設(shè)計(jì)

為解決當(dāng)前計(jì)算機(jī)串行通訊接口只有USB，難以滿足舊型號(hào)設(shè)備或某些單片機(jī)要求RS232通訊的問(wèn)題，設(shè)計(jì)出兩款RS232/USB電路。采用CH341A與MAX223集成電路芯片構(gòu)建標(biāo)準(zhǔn)9線RS232/USB通用接口轉(zhuǎn)換器，無(wú)需編程。采用CH341A與PIC16F877A構(gòu)建單片機(jī)與計(jì)算機(jī)之間的USB通訊電路，軟件遵循RS232通訊協(xié)議，硬件進(jìn)行電平轉(zhuǎn)換。實(shí)際使用表明，這兩款產(chǎn)品與計(jì)算機(jī)端Windows 操作系統(tǒng)下的串口應(yīng)用程序完全兼容，且通訊過(guò)程中無(wú)握手失敗現(xiàn)象。 Abstract:  To solve the problem that current computer serial communication only with USB interface can not satisfy with the old type equipments or MCU to communicate with RS232， two kinds of RS232/USB circuit were designed.CH341A and MAX223 integrated circuit chips were used to create a standard 9-line RS232/USB universal interface convertor without programme. CH341A and PIC16F877A chips were adopted to build the USB communication circuit between computers and MCU. The software follows RS232 communication protocol， and the hardware converts electrical levels. Actual practices indicate that the two manufactures are compatible with serial application program of Windows operation system completely，and get avoid of handshake lost.

基于C8051F020的通用串口適配器的設(shè)計(jì)

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.
