實(shí)現(xiàn)pc機(jī)鍵盤(pán)(p/s2接口)與8位單片機(jī)連接使用 原理:鍵盤(pán)時(shí)鐘接在p3.2口,既8051的外部中斷int0上,鍵盤(pán)數(shù)據(jù)接到p1.0上 每次按鍵,鍵盤(pán)會(huì)向單片機(jī)發(fā)脈沖使單片機(jī)發(fā)生外部中斷,數(shù)據(jù)有p1.0口一位一位傳進(jìn)來(lái) 傳回的數(shù)據(jù)格式為:1位開(kāi)始位(0),8位數(shù)據(jù)位(所按按鍵的通碼,用來(lái)識(shí)別按鍵),1位校驗(yàn)位(奇校驗(yàn)) 1位結(jié)束位(1) 實(shí)現(xiàn):將鍵盤(pán)發(fā)回的數(shù)據(jù)放到一個(gè)緩沖區(qū)里(數(shù)組),當(dāng)按鍵結(jié)束后發(fā)生內(nèi)部中斷來(lái)處理所按的按鍵 缺點(diǎn):由于51單片機(jī)的容量有限所以緩沖區(qū)不可以開(kāi)的太大,這就導(dǎo)致可以記錄鍵盤(pán)的按鍵次數(shù)過(guò)少, 也就是容錯(cuò)性一般。不過(guò)如果正常使用鍵盤(pán)是不會(huì)出錯(cuò)的

This code detects memory leaks in embedded VC++ almost the same way crtdbg does in VC++. At the end of program execution it will display in the debug window if there were any memory leaks and how the memory looks so you can identify where your memory leak occurred. It will display in the debug window a message saying no memory leaks detected if there are no memory leaks. Similar to what crtdbg.h does in VC++. The code detects memory leaks generated with calls to new and delete operators in C++. The code doesn t detect memory leaks generated with C functions: malloc, calloc, free, but that can be done in the future. Let me know and I will program it.
