【正文】 摘要 本文通過單片機(jī)的串口并經(jīng)過 MAX202 電平轉(zhuǎn)換，可 實(shí)現(xiàn)兩個單片機(jī)之間實(shí)時會話，半雙工工作模式 ；程序中設(shè)有發(fā)送接收允許、 自行校驗(yàn)， 提高了通信的準(zhǔn)確度； 可以 將接收數(shù)據(jù)儲存并 將儲存數(shù)據(jù)進(jìn)行讀取，可儲存 99 個數(shù)據(jù) ； 設(shè)有軟件復(fù)位功能，防止程序走死。 關(guān)鍵字： 實(shí)時會話 自行校驗(yàn) 軟件復(fù)位 Abstract Through and through the MAX202 chip serial level converter, enabling realtime conversation, halfduplex mode between two microcontrollers。 program features allow sending and receiving, self check and improve the accuracy of munication。 may be receiving data storage and store data read, can store 99 data。 has a software reset function to prevent the program go to die. Key words: live Session selfcalibration software reset session 1 目錄 摘要 ................................................................................................................................ 0 Abstract ........................................................................................................................... 0 目錄 ................................................................................................................................ 1 第 1 章 課題概述 ............................................................................................................ 2 第 2 章 總體設(shè)計方案 ..................................................................................................... 2 第 3 章 硬件設(shè)計 ............................................................................................................ 2 單片機(jī) .................................................................................................................. 2 UT62256CPCL 芯片 .............................................................................................. 2 單片機(jī)間串行通訊 ................................................................................................ 3 按鍵與顯示 ........................................................................................................... 3 軟件復(fù)位 ............................................................................................................... 3 讀取儲存數(shù)據(jù) ....................................................................................................... 3 第 4 章 軟件設(shè)計與調(diào)試 ................................................................................................. 4 待機(jī)界面 ............................................................................................................... 4 通信協(xié)議 ............................................................................................................... 4 發(fā)送接收允許 ................................................................................................. 4 自行校驗(yàn) ........................................................................................................ 4 軟件復(fù)位 ................................................................................................................ 5 儲存接收數(shù)據(jù) ....................................................................................................... 5 讀取接收數(shù)據(jù) ....................................................................................................... 5 總程序框圖 ........................................................................................................... 5 第
