【正文】 基于 USB接口的單片機(jī)與 PC機(jī)通信 摘 要 ： 安裝 USB設(shè)備不需要用戶自己設(shè)置硬件與軟件的選項(xiàng)， USB接口的傳輸速度要比計(jì)算機(jī)傳統(tǒng)的串行口和并口快的多，所以 USB設(shè)備已經(jīng)廣泛應(yīng)用。由于協(xié)議的復(fù)雜性，在系統(tǒng)中實(shí)現(xiàn) USB主機(jī)功能的實(shí)例還不是很多。因此本文沒(méi)有從復(fù)雜的 USB總線協(xié)議入手，而是選擇了南京沁恒公司出產(chǎn)的 USB接口芯片 CH375。 其具有內(nèi)置固件模式和可編程的 2311外部固件模式，可以根據(jù)需要任意選擇工作模式。 關(guān)鍵詞： 單片機(jī)； CH375； USB；協(xié)議 The Design of the munication between MCU and PC which is based on USB interface Abstract: USB device does not require users to install their own set of hardware and software options, and puter transmission speed faster than the traditional serial and parallel port , so USB devices have been widely used. Because of the plexity of the agreement, in the system of USB host function realization example is not a lot. Therefore this article does not starting with the plex USB agreement, but chose the USB interface chip CH375 which produced by Nanjing Qin Heng pany, their model has a builtin firmware and firmware programmable of 2311 external model, we can choose the mode of operation with a need for arbitrary. Key words: Single Chip Microcontroller。CH375。USB。Agreement 目 錄 1 前 言 .......................................................................................................................................1 題目的來(lái)源與開(kāi)發(fā)意義 ...................................................................................................1 系統(tǒng)功能概述 .................................................................................................................1 2 系統(tǒng)硬件設(shè)計(jì) ...........................................................................................................................2 方案論證 ........................................................................................................................2 系統(tǒng)硬件總體設(shè)計(jì)概述 ...................................................................................................2 系統(tǒng)功能概述 .................................................................................................................3 系統(tǒng)各模塊的設(shè)計(jì) ..........................................................................................................4 單片機(jī)控制系統(tǒng) ....................................................................................................4 USB 接口模塊 .......................................................................................................6 3 系統(tǒng)軟件設(shè)計(jì) ......................................................................................................................... 11 系統(tǒng)軟件總體設(shè)計(jì)思想 ................................................................................................. 11 各功能模塊軟件程序設(shè)計(jì) .............................................................................................. 11 4 系統(tǒng)調(diào)試 ................................................................................................................................ 16 硬件電路調(diào)試 ............................................................................................................... 16 各功能模塊軟件調(diào)試 ..................................................................................................... 16 5 結(jié)論 ....................................................................................................................................... 18 參考文獻(xiàn) ..................................................................................................................................... 19 致 謝 .......................................................................................................................................... 20 1 前 言 題目的來(lái)源與開(kāi)發(fā)意
